• gdb: Cannot find new threads: generic error

  - by Alexander Gladysh

  When I run GDB against a program which loads a .so which is linked to pthreads, GDB reports error "Cannot find new threads: generic error".

• Cannot call DLL import entry in C# from C++ project. EntryPointNotFoundException

  - by kriau

  I'm trying to call from C# a function in a custom DLL written in C++. However I'm getting the warning during code analysis and the error at runtime: Warning: CA1400 : Microsoft.Interoperability : Correct the declaration of 'SafeNativeMethods.SetHook()' so that it correctly points to an existing entry point in 'wi.dll'. The unmanaged entry point name currently linked to is SetHook. Error: System.EntryPointNotFoundException was unhandled. Unable to find an entry point named 'SetHook' in DLL 'wi.dll'. Both projects wi.dll and C# exe has been compiled in to the same DEBUG folder, both files reside here. There is only one file with the name wi.dll in the whole file system. C++ function definition looks like: #define WI_API __declspec(dllexport) bool WI_API SetHook(); I can see exported function using Dependency Walker: as decorated: bool SetHook(void) as undecorated: ?SetHook@@YA_NXZ C# DLL import looks like (I've defined these lines using CLRInsideOut from MSDN magazine): [DllImport("wi.dll", EntryPoint = "SetHook", CallingConvention = CallingConvention.Cdecl)] [return: MarshalAsAttribute(UnmanagedType.I1)] internal static extern bool SetHook(); I've tried without EntryPoint and CallingConvention definitions as well. Both projects are 32-bits, I'm using W7 64 bits, VS 2010 RC. I believe that I simply have overlooked something.... Thanks in advance.

• Why ntp settle time toe long?

  - by fercis

  I simply try to set-up NTP to my system. Both server and clients will run on my computer which are linked together with local link. One of them will have the reference clock. Both the server and Client are linux Ubuntu. I install ntp daemon to both sides. In clients, I enter the ip address of the server to /etc/ntp.conf. Everything works fine. However, the setting of the time to correct time in client side takes too long time (around 17 minutes). Is it possible to gather correct time just at startup. I write some code that regularly calls "ntpdate " by system call and the problem is solved but there has to be something that allows me to decrease the poll time of the client to 1-2 minutes. There are some settings as maxpoll - minpoll in ntp.conf, but I couldn't manage to understand their function, because with the best configuration (minpoll 4? 16 seconds?) I also cannot see that client side corrects its time before 10 minutes. In addition, in some cases my client is an embedded system (ARM - IGEP board) and it always opens with an irrelevant date (2-3 years ago). So the time that takes to correct the time should not depend on the time difference also.

• Component based web project directory layout with git and symlinks

  - by karlthorwald

  I am planning my directory structure for a linux/apache/php web project like this: Only www.example.com/webroot/ will be exposed in apache www.example.com/ webroot/ index.php comp1/ comp2/ component/ comp1/ comp1.class.php comp1.js comp2/ comp2.class.php comp2.css lib/ lib1/ lib1.class.php the component/ and lib/ directory will only be in the php path. To make the css and js files visible in the webroot directory I am planning to use symlinks. webroot/ index.php comp1/ comp1.js (symlinked) comp2/ comp2.css (symlinked) I tried following these principles: layout by components and libraries, not by file type and not by "public' or 'non public', index.php is an exception. This is for easier development. symlinking files that need to be public for the components and libs to a public location, but still mirroring the layout. So the component and library structure is also visible in the resulting html code in the links, which might help development. git usage should be safe and always work. it would be ok to follow some procedure to add a symlink to git, but after that checking them out or changing branches should be handled safely and clean How will git handle the symlinking of the single files correctly, is there something to consider? When it comes to images I will need to link directories, how to handle that with git? component/ comp3/ comp3.class.php img/ img1.jpg img2.jpg img3.jpg They should be linked here: webroot/ comp3/ img/ (symlinked ?) If using symlinks for that has disadvantages maybe I could move images to the webroot/ tree directly, which would break the first principle for the third (git practicability). So this is a git and symlink question. But I would be interested to hear comments about the php layout, maybe you want to use the comment function for this.

• CEIL is one too high for exact integer divisions

  - by Synetech

  This morning I lost a bunch of files, but because the volume they were one was both internally and externally defragmented, all of the information necessary for a 100% recovery is available; I just need to fill in the FAT where required. I wrote a program to do this and tested it on a copy of the FAT that I dumped to a file and it works perfectly except that for a few of the files (17 out of 526), the FAT chain is one single cluster too long, and thus cross-linked with the next file. Fortunately I know exactly what the problem is. I used ceil in my EOF calculation because even a single byte over will require a whole extra cluster: //Cluster is the starting cluster of the file //Size is the size (in bytes) of the file //BPC is the number of bytes per cluster //NumClust is the number of clusters in the file //EOF is the last cluster of the file’s FAT chain DWORD NumClust = ceil( (float)(Size / BPC) ) DWORD EOF = Cluster + NumClust; This algorithm works fine for everything except files whose size happens to be exactly a multiple of the cluster size, in which case they end up being one cluster too much. I thought about it for a while but am at a loss as to a way to do this. It seems like it should be simple but somehow it is surprisingly tricky. What formula would work for files of any size?

• ASP: Assigning CSS to dynamically created Label in C#

  - by Tucker

  I'm trying to figure out how to apply CSS to a Label created in C#. Everything compiles and runs, it just doesn't seem to be applying the CSS. The CSS is in the file linked to in the site master page. Everything else in the CSS file is being applied as it should be. Codebehind: ... Label label = new Label(); SqlCommand command = new SqlCommand("SELECT Q_Text FROM HRA.dbo.Questions WHERE QID = 1"); command.Connection = connection; reader = command.ExecuteReader(); reader.Read(); label.Text = reader["Q_Text"].ToString(); label.ID = "rblabel"; label.CssClass = "rblabel"; reader.Close(); ... ASP: <asp:Content runat="server" ID="BodyContent" ContentPlaceHolderID="MainContent"> <asp:PlaceHolder ID="holder" runat="server"> </asp:PlaceHolder> </asp:Content> CSS: .rblabel { text-align:left; padding-left: 2em; font-size: 4em; }

• How is it legal to reference an undefined type inside a structure?

  - by paxdiablo

  As part of answering another question, I came across a piece of code like this, which gcc compiles without complaint. typedef struct { struct xyz *z; } xyz; int main (void) { return 0; } This is the means I've always used to construct types that point to themselves (e.g., linked lists) but I've always thought you had to name the struct so you could use self-reference. In other words, you couldn't use xyz *z within the structure because the typedef is not yet complete at that point. But this particular sample does not name the structure and it still compiles. I thought originally there was some black magic going on in the compiler that automatically translated the above code because the structure and typedef names were the same. But this little beauty works as well: typedef struct { struct NOTHING_LIKE_xyz *z; } xyz; What am I missing here? This seems a clear violation since there is no struct NOTHING_LIKE_xyz type defined anywhere. When I change it from a pointer to an actual type, I get the expected error: typedef struct { struct NOTHING_LIKE_xyz z; } xyz; qqq.c:2: error: field `z' has incomplete type Also, when I remove the struct, I get an error (parse error before "NOTHING ...). Is this allowed in ISO C?

• Redirecting users after destroy

  - by mathee

  I have 3 models: Questions, Answers, and Profiles (I know, it should be called "Users"). When you view a question Q, I query the database for the answers to Q. (They are linked by id.) In the view, the current user has the option to delete his answer by clicking on the destroy link displayed next to his answer: %table %tr %td Answers: - @answers.each do |a| %tr %td - @provider = Profile.find(a.provider) %i #{h @provider.username} said: %br #{h a.description} %td = link_to 'View full answer', a %td - if a.provider == @profile.id #{link_to 'Delete my answer', a, :confirm => 'Are you sure?', :method => :delete} The problem is that when the user clicks on the destroy link, it redirects to the /answers/index. I want it to redirect to /questions/Q. What's the best way to do this? I know that there's a redirect_to method, but I don't know how to implement it when I want to redirect to an action for a different controller. It also needs to remember the question from which the answer is being deleted. I tried passing something like :question_id in link_to as: #{link_to 'Delete my answer', a, :confirm => 'Are you sure?', :question_id => @question.id, :method => :delete} In AnswersController#destroy: def destroy @answer = Answer.find(params[:id]) @answer.destroy respond_to do |format| format.html { redirect_to(answers_url) } format.xml { head :ok } end @question = Question.find(params[:question_id]) redirect_to question_path(@question) end The :question_id information is not passed to the destroy method, so I get this error: Couldn't find Question without an ID To confirm, I added a puts call before Question.find, and it returned nil.

• Playing video and audio in iPhone not working...

  - by Scott

  So we have buttons linked up to display images/videos/audio on click depending on a check we do earlier. That part works fine. It knows which one to play, however, when we click the buttons for video and audio, nothing happens. The image one works fine. The video and audio are being taken for a URL online, they are not local, but everywhere said this was still possible. Here is a little snippet of the code where we play the two files: if ( [fName hasSuffix:@".png"]) { NSLog(@"PICTURE"); NSURL *url = [NSURL URLWithString: fName]; UIImage *image = [UIImage imageWithData: [NSData dataWithContentsOfURL:url]]; self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; // self.view.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"MainBG.jpg"]]; [self.view addSubview:[[UIImageView alloc] initWithImage:image]]; } if ( [fName hasSuffix:@".mp4"]) { NSLog(@"VIDEO"); //NSString *path = [[NSBundle mainBundle] pathForResource:fName ofType:@"mp4"]; //NSLog(path); NSURL *url = [NSURL fileURLWithPath:fName]; MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:url]; [player play]; } if ( [fName hasSuffix:@".mp3"]) { NSLog(@"AUDIO"); NSURL *url = [NSURL fileURLWithPath:fName]; NSData *soundData = [NSData dataWithContentsOfURL:url]; AVAudioPlayer *avPlayer = [[AVAudioPlayer alloc] initWithData:soundData error: nil]; [avPlayer play]; } See anything wrong? By the way it compiles and runs, but nothing happens when we hit the button that executes that code.

• Hashtable resizing leaks memory

  - by thpetrus

  I wrote a hashtable and it basically consists of these two structures: typedef struct dictEntry { void *key; void *value; struct dictEntry *next; } dictEntry; typedef struct dict { dictEntry **table; unsigned long size; unsigned long items; } dict; dict.table is a multidimensional array, which contains all the stored key/value pair, which again are a linked list. If half of the hashtable is full, I expand it by doubling the size and rehashing it: dict *_dictRehash(dict *d) { int i; dict *_d; dictEntry *dit; _d = dictCreate(d->size * 2); for (i = 0; i < d->size; i++) { for (dit = d->table[i]; dit != NULL; dit = dit->next) { _dictAddRaw(_d, dit); } } /* FIXME memory leak because the old dict can never be freed */ free(d); // seg fault return _d; } The function above uses the pointers from the old hash table and stores it in the newly created one. When freeing the old dict d a Segmentation Fault occurs. How am I able to free the old hashtable struct without having to allocate the memory for the key/value pairs again?

• Building a ctypes-"based" C library with distutils

  - by Robie Basak

  Following this recommendation, I have written a native C extension library to optimise part of a Python module via ctypes. I chose ctypes over writing a CPython-native library because it was quicker and easier (just a few functions with all tight loops inside). I've now hit a snag. If I want my work to be easily installable using distutils using python setup.py install, then distutils needs to be able to build my shared library and install it (presumably into /usr/lib/myproject). However, this not a Python extension module, and so as far as I can tell, distutils cannot do this. I've found a few references to people other people with this problem: Someone on numpy-discussion with a hack back in 2006. Somebody asking on distutils-sig and not getting an answer. Somebody asking on the main python list and being pointed to the innards of an existing project. I am aware that I can do something native and not use distutils for the shared library, or indeed use my distribution's packaging system. My concern is that this will limit usability as not everyone will be able to install it easily. So my question is: what is the current best way of distributing a shared library with distutils that will be used by ctypes but otherwise is OS-native and not a Python extension module? Feel free to answer with one of the hacks linked to above if you can expand on it and justify why that is the best way. If there is nothing better, at least all the information will be in one place.

• WordPress plugin to output a certain category on content page tweak help

  - by talkingD0G

  I'm using WordPress plugin Category Page to display the most recent 5 posts from a certain category on a regular content page (not the blog page) of a website. Right now the plugin is limited to display the post title linked to the post page. This is a video blog type site and I need the plugin to display the post title (as it does now) with the video as well. Probably just telling the script to show the content would work but I don't know how to tweak it. This is the section of the script that is outputting the post title: function page2cat_content_catlist($content){ global $post; if ( stristr( $content, '[catlist' )) { $search = "@(?:<p>)*\s*\[catlist\s*=\s*(\w+|^\+)\]\s*(?:</p>)*@i"; if (preg_match_all($search, $content, $matches)) { if (is_array($matches)) { $title = get_option('p2c_catlist_title'); if($title != "") $output = "<h4>".$title."</h4>"; else $output = ""; $output .= "<ul class='p2c_catlist'>"; $limit = get_option('p2c_catlist_limit'); foreach ($matches[1] as $key =>$v0) { $catposts = get_posts('category='.$v0."&numberposts=".$limit); foreach($catposts as $single): $output .= "<li><a href='".get_permalink($single->ID)." '>".$single->post_title."</a></li>"; endforeach; $search = $matches[0][$key]; $replace= $output; $content= str_replace ($search, $replace, $content); } $output .= "</ul>"; } } } return $content; } If anyone has any advice or knows how to help thanks in advance!

• Reversing a circular deque without a sentinel

  - by SDLFunTimes

  Hey Stackoverflow I'm working on my homework and I'm trying to reverse a circular-linked deque without a sentinel. Here are my data structures: struct DLink { TYPE value; struct DLink * next; struct DLink * prev; }; struct cirListDeque { int size; struct DLink *back; }; Here's my approach to reversing the deque: void reverseCirListDeque(struct cirListDeque* q) { struct DLink* current; struct DLink* temp; temp = q->back->next; q->back->next = q->back->prev; q->back->prev = temp; current = q->back->next; while(current != q->back->next) { temp = current->next; current->next = current->prev; current->prev = temp; current = current->next; } } However when I run it and put values 1, 2 and 3 on it (TYPE is just a alias for int in this case) and reverse it I get 2, 3, null. Does anyone have any ideas as to what I may be doing wrong? Thanks in advance.

• What VC++ compiler/linker does when building a C++ project with Managed Extension

  - by ???

  The initial problem is that I tried to rebuild a C++ project with debug symbols and copied it to test machine, The output of the project is external COM server(.exe file). When calling the COM interface function, there's a RPC call failre: COMException(0x800706BE): The remote procedure call failed. According to the COM HRESULT design, if the FACILITY code is 7, it's actually a WIN32 error, and the win32 error code is 0x6BE, which is the above mentioned "remote procedure call failed". All I do is replace the COM server .exe file, the origin file works well. When I checked into the project, I found it's a C++ project with Managed Extension. When I checking the DLL with reflector, it shows there's 2 additional .NET assembly reference. Then I checked the project setting and found nothing about the extra 2 assembly reference. I turned on the show includes option of compiler and verbose library of linker, and try to analyze whether the assembly is indirectly referenced via .h file. I've collect all the .h file and grep all the files with '#using' '#import' and the assembly file itself. There really is a '#using ' in one of the .h file but not-relevant to the referenced assembly. And about the linked .lib library files, only one of the .lib file is a side-product of another managed-extension-enabled C++ project, all others are produced by a pure, traditional C++ project. For the managed-extension-enabled C++ project, I checked the output DLL assembly, it did NOT reference to the 2 assembly. I even try to capture the access of the additional assembly file via sysinternal's filemon and procmon, but the rebuild process does NOT access these file. I'm very confused about the compile and linking process model of a VC++/CLI project, where the additional assembly reference slipped into the final assembly? Thanks in advance for any of your help.

• std::list : get next element

  - by sheepsimulator

  I'm trying to build a string using data elements stored in a std::list, where I want commas placed only between the elements (ie, if elements are {A,B,C,D} in list, result string should be "A,B,C,D". This code does not work: typedef std::list< shared_ptr<EventDataItem> > DataItemList; // ... std::string Compose(DataItemList& dilList) { std::stringstream ssDataSegment; for(iterItems = dilList.begin(); iterItems = dilList.end(); iterItems++) { // Lookahead in list to see if next element is end if((iterItems + 1) == dilList.end()) { ssDataSegment << (*iterItems)->ToString(); } else { ssDataSegment << (*iterItems)->ToString() << ","; } } return ssDataSegment.str(); } How do I get at "the-next-item" in a std::list using an iterator? I would expect that it's a linked-list, why can't I get at the next item?

• Why are my event listeners firing more than once?

  - by Arms

  In my Flash project I have a movieclip that has 2 keyframes. Both frames contain 1 movieclip each. frame 1 - Landing frame 2 - Game The flow of the application is simple: User arrives on landing page (frame 1) User clicks "start game" button User is brought to the game page (frame 2) When the game is over, the user can press a "play again" button which brings them back to step 1 Both Landing and Game movieclips are linked to separate classes that define event listeners. The problem is that when I end up back at step 1 after playing the game, the Game event listeners fire twice for their respective event. And if I go through the process a third time, the event listeners fire three times for every event. This keeps happening, so if I loop through the application flow 7 times, the event listeners fire seven times. I don't understand why this is happening because on frame 1, the Game movieclip (and I would assume its related class instance) does not exist - but I'm clearly missing something here. I've run into this problem in other projects too, and tried fixing it by first checking if the event listeners existed and only defining them if they didn't, but I ended up with unexpected results that didn't really solve the problem. I need to ensure that the event listeners only fire once. Any advice & insight would be greatly appreciated, thanks!

• Using a randomly generated token for flood control.

  - by James P

  Basic setup of my site is: user enters a message on the homepage, hits enter and the message is sent though a AJAX request to a file called like.php where it echo's a link that gets sent back to the user. I have made the input disable when the user presses enter, but there's nothing stopping the user from just constantly flooding like.php with POST request and filling up my database. Someone here on SO told me to use a token system but didn't mention how. I've seen this being done before and from what I know it is effective. The only problem I have is how will like.php know it's a valid token? My code is this at the moment: $token = md5(rand(0, 9999) * 1000000); and the markup: <input type="hidden" name="token" value="<?php echo $token ?>" /> Which will send the token to like.php through POST. But how will like.php know that this is a valid token? Should I instead token something that's linked to the user? Like their IP address? Or perhaps token the current minute and check that it's the same minute in like.php... Any help on this amtter would be greatly appreciated, thanks. :)

• Build a Visual Studio Project without access to referenced dlls

  - by David Reis

  I have a project which has a set of binary dependencies (assembly dlls for which I do no have the source code). At runtime those dependencies are required pre-installed on the machine and at compile time they are required in the source tree, e,g in a lib folder. As I'm also making source code available for this program I would like to enable a simple download and build experience for it. Unfortunately I cannot redistribute the dlls, and that complicates things, since VS wont link the project without access to the referenced dlls. Is there anyway to enable this project to be built and linked in absence of the real referenced dlls? Maybe theres a way to tell VS to link against an auto generated stub of the dll, so that it can rebuild without the original? Maybe there's a third party tool that will do this? Any clues or best practices at all in this area? I realize the person must have access to the dlls to run the code, so it makes sense that he could add them to the build process, but I'm just trying to save them the pain of collecting all the dlls and placing them in the lib folder manually.

• How to make flash movie to scale proportunatly to div width?

  - by user73119

  I have put together an example page detailing my problem My website is going to have a main wrapper that is set to a max-width property for compatible browsers. It will stretch to 940px across at max. When scaled down I would like the swf to scale proportionately with it. Like an image with width percent applied. The flash movie has the dimensions of 940 × 360 pixels. I can't seem to figure out the correct attributes to add to the embed tag to get it to do this. I am currently using jquery flash embed, but am open to other options, though this is my ideal. In the example I have set the flash background to black. When resize the browser window the flash movie doesn't scale proportionately to the div, only the photo does, leaving a blank canvas (black), while the div height stays the same. I can't add a height value in the CSS. How do I make this scale correctly? Adding a noscale param only crops the image. The swf's height doesn't scale also. All of my code can be viewed in the linked examples source.

• Time complexity to fill hash table (homework)?

  - by Heathcliff

  This is a homework question, but I think there's something missing from it. It asks: Provide a sequence of m keys to fill a hash table implemented with linear probing, such that the time to fill it is minimum. And then Provide another sequence of m keys, but such that the time fill it is maximum. Repeat these two questions if the hash table implements quadratic probing I can only assume that the hash table has size m, both because it's the only number given and because we have been using that letter to address a hash table size before when describing the load factor. But I can't think of any sequence to do the first without knowing the hash function that hashes the sequence into the table. If it is a bad hash function, such that, for instance, it hashes every entry to the same index, then both the minimum and maximum time to fill it will take O(n) time, regardless of what the sequence looks like. And in the average case, where I assume the hash function is OK, how am I suppossed to know how long it will take for that hash function to fill the table? Aren't these questions linked to the hash function stronger than they are to the sequence that is hashed? As for the second question, I can assume that, regardless of the hash function, a sequence of size m with the same key repeated m-times will provide the maximum time, because it will cause linear probing from the second entry on. I think that will take O(n) time. Is that correct? Thanks

• ParseKit.framework won't work, Foundation.h not found

  - by Jeremy

  I'm really stumped trying to get the ParseKit.framework (this) to work in general, not even bothering to implement it till it runs the demo app that comes with it. What happens is the compiler can't locate < Foundation/Foundation.h or something, which I thought the header was in the linked framework. Exact error: "Lexical or Preprocessor Issue: 'Foundation/Foundation.h' file not found." Here's the code, just from the ParseKit_Prefix.pch: // // Prefix header for all source files of the 'ParseKit' target in the 'ParseKit' project. //#ifdef __OBJC__ #import <Foundation/Foundation.h> #endif Nothing unusual about it, did I mess up the file paths some how? I've reinstalled Xcode, re-downloaded the ParseKit, and nothing is helping. The suggestions here did nothing and it's not this. When I make a new project or use a different project and load the Foundation.framework and #import the header it works just fine. If I unlink the framework I can't find it to re-link again. Has anyone else had this kind of problem? Did I download it wrong somewhere? I have a very difficult time finding where exactly the Xcode UI links stuff, apple must get a kick out of frustrating people, so if anyone has anything they can think of please give me some feedback, I'm horribly confused right now. Thanks,

• Why is Firefox prompting to download a file that is POST'd to?

  - by alex

  This is the most peculiar thing. It is from an old in house CMS. When I attempt to submit my changes, it prompts to save the file linked in the action attribute of the form. Headers Request POST /~site/edit/articles/article_save.php?id=54 HTTP/1.1 Host: example.com User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Referer: http://example.com Content-Type: multipart/form-data; boundary=---------------------------10102754414578508781458777923 Content-Length: 940 -----------------------------10102754414578508781458777923 Content-Disposition: form-data; name="title" Home Content -----------------------------10102754414578508781458777923 Content-Disposition: form-data; name="catid" 18 -----------------------------10102754414578508781458777923 Content-Disposition: form-data; name="activecheck" 1 -----------------------------10102754414578508781458777923 Content-Disposition: form-data; name="image" -----------------------------10102754414578508781458777923 Content-Disposition: form-data; name="contentWidgToolbarSelectBlock" <p> -----------------------------10102754414578508781458777923 Content-Disposition: form-data; name="content" <p>Edit your article in this text box.</p> -----------------------------10102754414578508781458777923 Content-Disposition: form-data; name="contentWidgEditor" true -----------------------------10102754414578508781458777923-- Response HTTP/0.9 200 OK And then Firefox shows.... I can't determine from the response headers as to why this is prompting to open/save. It has always worked. All other PHP files on the site work fine. Anyone have a clue? Thanks Update Apparently, it just crashes Safari.

• LuaEdit can't find module when Lua files all in the same folder

  - by joverboard

  I downloaded LuaEdit to use as an IDE and debug tool however I'm having trouble using it for even the simplest things. I've created a solution with 2 files in it, all of which are stored in the same folder. My files are as follows: --startup.lua require("foo") test("Testing", "testing", "one, two, three") --foo.lua foo = {} print("In foo.lua") function test(a,b,c) print(a,b,c) end This works fine when in my C++ compiler when accessed through some embed code, however when I attempt to use the same code in LuaEdit, it crashes on line 3 require("foo") with an error stating: module 'foo' not found: no field package.preload['foo'] no file 'C:\Program Files (x86)\LuaEdit 2010\lua\foo.lua' no file 'C:\Program Files (x86)\LuaEdit 2010\lua\foo\init.lua' no file 'C:\Program Files (x86)\LuaEdit 2010\foo.lua' no file 'C:\Program Files (x86)\LuaEdit 2010\foo\init.lua' no file '.\foo.lua' no file 'C:\Program Files (x86)\LuaEdit 2010\foo.dll' no file 'C:\Program Files (x86)\LuaEdit 2010\loadall.dll' no file '.\battle.dll' I have also tried creating these files prior to adding them to a solution and still get the same error. Is there some setting I'm missing? It would be great to have an IDE/debugger but it's useless to me if it can't run linked functions.
