  • Eclipse Pydev: Supress no-self errors in python wrappers generated with swig

    - by Christian
    Hi, when generating python wrappers with swig the python wrapper classes in the generated python file do not have an explicit self parameter, for example see below: class PySwigIterator(_object): def value(*args): return _spatiotemporalnmf.PySwigIterator_value(*args) def incr(*args): return _spatiotemporalnmf.PySwigIterator_incr(*args) def decr(*args): return _spatiotemporalnmf.PySwigIterator_decr(*args) def distance(*args): return _spatiotemporalnmf.PySwigIterator_distance(*args) I am developing with the eclipse pluging Pydev. Pydev always shows an error when it detects a method without explicit self parameter. I am aware of two methods to get rid of the errors: First, disable error checking for the whole project in the Pydev preferences. Second, add a #@NoSelf to every line with an error. I don't want to use the first one, because I still want to get error warnings for my non-swig-generated files. Obviously the second one is also not very good, because I would have to do it by hand and every time I generate the file again, all #@NoSelfs will be gone. My Question now is, is there a better way to achieve this? Thanks

  • Static libpng link with visual studio 2010

    - by Sanctus2099
    Hey guys. I'm trying to add PNG support to my application and thus I want to include libpng. I know it needs zlib and thus I downloaded that as well. I went into the png folder/projects/vstudio and I opened the solution. I compiled it and it went just fine. I added some headers from it into my application and I copied the lib files. My program is a dll written in c++ which is later used from C#. When I run it in C# it complains about not finding my dll (tough if I remove the png part it works fine). I've had this problem before and it usually means a dll dependency is wrong. Now... libpng compiled both some .lib files and some .dll files. The dll files are bigger. My only guess is that it needs the dll files as well but I've seen that people can link to libpng without a dll. So my questions is: How can I compile libpng(and zlib for that instance) into just static libraries and how can I include those in my projects? I've searched around the internet and I couldn't find anything useful.

  • Xcode Link Frameworks "Relative to Current SDK" Doesn't Work When Mixing Mac Framework and iPhone St

    - by bl4th3rsk1t3
    I have a framework of code I maintain. It's got mac and iphone objective-c code. And some of it is shared. I'm not having any problems with code. It's a problem with Xcode. Let's just call my framework "AwesomeKit" for this problem. The first thing I did was create an xcode Framework project called "AwesomeKit". Add source files to it, link against the common mac frameworks: foundation, cocoa, carbon, etc. It compiles fine. Then, add a new "static library" target, let's call it "AwesomeKit-iPhone" and set the base SDK in the build settings to iphone device 3.1.3. The problem comes when I try to add "Existing Frameworks" to the AweseomKit-iPhone target. -First change the current build target to AwesomeKit-iPhone. -Right click on any group and select "Add Existing Frameworks..." -Choose UIKit.framework UIKit will immediately be highlighted red, as if it's missing. It is indeed missing because Xcode uses the "Relative SDK" setting from the "Mac OS 10.6" SDK. When it should be using it relative to the current target's base sdk iphone device 3.1.3. What the heck? Has anyone experienced this? This is really annoying.

  • shared library path inconsistent from one host to another

    - by yan bellavance
    I built my qt app so that all the Qt modules it uses are contained in the same directory as the executable. It works on the machine I used to build the app and I made sure to test this by removing those shared libraries everywhere except in the current directory of the app. Doing a ldd shows that its looking for those libraries in the current directory and putting the executable by itself fails to open the exectuable. So this is all good but when I transfer this directory to a host machine it still cant find those libraries. what could be the problem?

  • AJAX deeplinking with jQuery Address

    - by antosha
    Hello, I have a website which has many pages: For example: HOME: http://mywebsite.com/index.html SOME PAGE: http://mywebsite.com/categorie/somepage.html I decided to make my pages load dynamically with AJAX without reloading the page. So I decided to use jQuery Address plugin ( http://www.asual.com/jquery/address/docs/ ) in order to allow deeplinking and Back-Forward navigation: <script type="text/javascript" src="uploads/scripts/jquery.address-1.2rc.min.js"></script> <script type="text/javascript"> $('a').address(function() { return $(this).attr('href').replace(/^#/, ''); }); </script> Now, after installing the plugin, if I go on http://mywebsite.com/index.html (HOME) and click on SOME PAGE link, jquery successfully loads the http://mywebsite.com/categorie/somepage.html without reloading the page and the address bar on my browser displays: http://mywebsite.com/index.html/#/categorie/somepage.html which is great! However, the problem is: if I copy this dynamically generated URL: http://mywebsite.com/index.html/#/categorie/somepage.html into a web browser address bar, it will take into my website index.html page and not to the "SOME PAGE" page. Also, The Forward/Back buttons don't work correctly, they only replace the address in the URL bar but the content stays the same. I suppose that I need to write some JavaScript rule that associates the dynamic URL with the correct page? Some help would be appreciated. Thanks :)

  • JNI problem when calling a native library that loads another native library

    - by TheEnemyOfQuality
    I've got a bit of an odd problem. I have a project in C++ that's basically a wrapper for a third party DLL like this: MyLibrary --loads DLL_A ----loads DLL_B I load DLL_A with LoadLibrary(), wrap several of its functions and generate my own DLL. I've tested this in a C++ project and a C# project. Both do everything they're supposed to do: load DLL_A, make a couple of function calls, and indirectly load DLL_B. The problem is when I build a DLL for java and make the calls through JNI. Everything runs like it should (no java.lang.UnsatisfiedLinkError), but when it comes time for DLL_A to load DLL_B it doesn't work. From debugging, the loading of DLL_B happens on a function call in DLL_A that takes a callback. When called from Java, this function call seems to fail (the function pointer is fine and the actual call goes off without a hitch), and I get an odd pop-up window saying DLL_B failed to load, and my program is left waiting for a callback that never happens. I can explicitly load DLL_B just fine (both from Java and from C++) and I've checked every possible path, path variable, and tried placing the dlls everywhere to see if it could be looking somewhere funny. I'm pretty sure it's not a path problem. Ultimately I don't know how DLL_A is loading DLL_B and I can't figure out why everything works fine in C++ and C#, but not in Java. I'm absolutely flummoxed. It could still be something specific to my setup (although I've looked as hard as I can look), but I'm throwing this scenario out there to see if anyone has run into a similar problem. -Dave

  • How do I link against Intel TBB on Mac OS X with GCC?

    - by SilverSun
    I can't for the life of me figure out how to compile and link against the Intel TBB library on my Mac. I've run the commercial installer and the tbbvars.sh script but I can't figure this out. I have a feeling it is something really obvious and it's just been a bit too long since I've done this kind of thing. tbb_test.cpp #include <tbb/concurrent_queue.h> int main() { tbb::concurrent_queue<int> q; } g++ tbb_test.cpp -I /Library/Frameworks/TBB.framework/Headers -ltbb ...can't find the symbols. Cheers!

  • Internet Explorer blocked this website from displaying content with security certificate errors

    - by Tabrez
    I have a security certificate linked to a CDN's server. The main website is https:www.connect4fitness.com When I pull the site up in firefox or chrome, everything works fine. But in IE I get the following error: "Internet Explorer blocked this website from displaying content with security certificate errors." On IE 9 it shows the button "Display Content" and you can get past the error by clicking on the button. On older versions on I the error message is much more cryptic and is confusing users. Please note that I don't have the option of asking end users to add the site to Trusted Sources as some folks use the site from their work computers and do not have that access. Also, some people don't bother to call once they hit the error. I have looked at the content and all my links are "https" only. I had one namespace link and I got rid of it. Any idea about how I can find what is triggering this message?

  • Locating binding errors

    - by softengine
    I'm dealing with a large WPF application that is outputting a large number of binding errors. A typical error looks like this: System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Controls.ItemsControl', AncestorLevel='1''. BindingExpression:Path=HorizontalContentAlignment; DataItem=null; target element is 'MenuItem' (Name=''); target property is 'HorizontalContentAlignment' (type 'HorizontalAlignment') Problem is I don't know where in the app this is coming from. Searching the entire solution for AncestorType={x:Type ItemsControl} doesn't necessary help since I still don't know which result is the culprit. I've tried setting PresentationTraceSources.DataBindingSource.Switch.Level = SourceLevels.All; but the extra information doesn't help locate the problematic bindings. File names and line numbers is really what I need. Is there anyway to get this information?

  • Linux, static lib referring to other static lib within an executable

    - by andras
    Hello, I am creating an application, which consists of two static libs and an executable. Let's call the two static libs: libusefulclass.a libcore.a And the application: myapp libcore instantiates and uses the class defined in libusefulclass (let's call it UsefulClass) Now, if I link the application in the following way: g++ -m64 -Wl,-rpath,/usr/local/Trolltech/Qt-4.5.4/lib -o myapp src1.o src2.o srcN.o -lusefulclass -lcore The linker complains about the methods in libusefulclass not being found: undefined reference to `UsefulClass::foo()' etc. I found a workaround for this: If UsefulClass is also instantiated within the source files of the executable itself, the application is linked without any problems. My question is: is there a more clean way to make libcore refer to methods defined in libusefulclass, or static libs just cannot be linked against eachother? TIA P.S.: In case that matters: the application is being developed in C++ using Qt, but I feel this is not a Qt problem, but a library problem in general.

  • Need help with Javascript....I think

    - by Mikey
    I'm trying to bypass going through a bunch of menus, to get to the data I want directly. Here are the links I want to go to: http://factfinder.census.gov/servlet/MapItDrawServlet?geo_id=14000US53053072904&tree_id=4001&context=dt&_lang=en&_ts=288363511701 factfinder.census.gov/servlet/MapItDrawServlet?geo_id=14000US53025981400&tree_id=4001&context=dt&_lang=en&_ts=288363511701 factfinder.census.gov/servlet/MapItDrawServlet?geo_id=14000US53067011620&tree_id=4001&context=dt&_lang=en&_ts=288363511701 Notice, if you pull that up right now, you simply see a GIF outline of the map, however there is no map data "behind" it. However, if you go to: factfinder.census.gov/servlet/DTGeoSearchByListServlet?ds_name=DEC_2000_SF1_U&_lang=en&_ts=288392632118 Select Geographic Type: ..... ..... Census Tract Select a State: Washington Select a County: Pierce Select one or more geographic areas: Census Tract 729.04 Hit "Map It" The map will load perfectly. Also, until you close your browser, any of the other links will work perfectly. What I want to do, is be able to bypass these 5 steps, but obviously something is preventing this. Is there a feasible workaround? I have my own domain that I would be able to upload new Javascript or HTML files or whatever is needed.

  • configure.in: AM_DISABLE_SHARED doesn't change my Makefile

    - by t2k32316
    I'm extremely new to using Makefiles and autoconf. I'm using the Camellia image library and trying to statically link my code against their libraries. When I run "make" on the Camellia image library, I get libCamellia.a, .so, .la, and .so.0.0.0 files inside my /usr/local/lib directory. This is the command I use to compile my code with their libraries: gcc -L/usr/local/lib -lCamellia -o myprogram myprogram.c This works fine, but when I try to statically link, this is what I get: gcc -static -L/usr/local/lib -lCamellia -o myprogram myprogram.c /tmp/cck0pw70.o: In function `main': myprogram.c:(.text+0x23): undefined reference to `camLoadPGM' myprogram.c:(.text+0x55): undefined reference to `camAllocateImage' myprogram.c:(.text+0x97): undefined reference to `camZoom2x' myprogram.c:(.text+0x104): undefined reference to `camSavePGM' collect2: ld returned 1 exit status I want to statically link because I'm trying to modify the Camellia source code and I want to compare my version against theirs. So after some googling, I tried adding AM_DISABLE_SHARED into the configure.in file. But after running ./configure, I still get the exact same Makefile. After I "make install", I still get the same results above. What is an easy way to get two versions of my code, one with the original Camellia source code compiled and one with my modified version? I think static libraries should work. There is an easy way to get static libraries working or are there other simple solutions to my problem? I just don't want to re-"make" and re-"make install" everytime I want to compare my version against the original.

  • how to make a explorer like logic in Obj C for iphone

    - by Ekra
    Hi friends, To make the query simple first we can take example:- If we open the explorer in our Windows desktop how it shows us the tree. As we keep on clicking the tree it get expanded and shows the file in it. The same way I want to show a explorer which gets expanded as the user clicks on it(I want to get the business logic the UI is simple). The information of the explorer i.e. which folder has what files come in a XML format to me. I have 2 options of getting the XML either I can get the whole XML at one query(but I guess this might slow the application if the XML is quite big). OR I can get the XML for every list like first only the root structure then if user clicks on any folder in root I can get the list(the files or folders inside that folder) of that particular folder. Now the question is What would be the approach to implement both the method and which would be the best. Should I need to create some dictionary to maintain the link of the files like which file is inside what. I am not able to get as how I would be able to link all the files. Any hint or direction would be highly appreciated. Thanks in advance

  • How does symbol binding work for shared libraries in linux

    - by bbazso
    When compiling a cpp program with g++ -O0 I noticed that my binary does not contain the symbol for the empty string (basic_string): _S_empty_rep_storage When I do compile this same program with -O2 I notice that the aforementioned symbol is indeed contained within the binary as follows (using nm on the bin): 00000000006029a0 V _ZNSs4_Rep20_S_empty_rep_storageE@@GLIBCXX_3.4 My application uses several .so (dynamic libraries) and when my aplication loads I notice that several of these .so files bind as follows (I set LD_DEBUG=all and ran my program): 28596: binding file /home/bbazso/usr/local/lib/mydynamiclib.so [0] to /usr/lib64/libstdc++.so.6 [0]: normal symbol `_ZNSs4_Rep20_S_empty_rep_storageE' [GLIBCXX_3.4] 28596: binding file /home/bbazso/usr/local/lib/mydynamiclib.so [0] to /home/bbazso/workspace/mytestapplication [0]: normal symbol `_ZNSs4_Rep20_S_empty_rep_storageE' [GLIBCXX_3.4] 28596: binding file /home/bbazso/workspace/mytestapplication [0] to /usr/lib64/libstdc++.so.6 [0]: normal symbol `_ZNSs4_Rep20_S_empty_rep_storageE' [GLIBCXX_3.4]** But I also noticed that one of my .so only binds as follows: 28087: binding file /home/bbazso/usr/local/lib/anotherdynamiclib.so [0] to /usr/lib64/libstdc++.so.6 [0]: normal symbol `_ZNSs4_Rep20_S_empty_rep_storageE' [GLIBCXX_3.4] but never binds to the binary (mytestapplication) as shown above for the mydynamiclib.so. So I was wondering what this actually means? Does this mean that anotherdynamiclib.so will use a different symbol for the empty string above than the rest of the application? I guess what I'm really asking is how does symbol binding work in the context of the example above? Thanks!

  • Deeplinking with SWFAddress and Facebook connect

  • Returning errors from AMFPHP on purpose.

    When using flash remoting with amfphp, what can I write in php that will trigger the 'status' method that I set up in my Responder in Flash? Or more generally, how can I determine if the service call has failed? The ideal solution for me would be to throw some exception in php serverside, and catch that exception in flash clientside... How do other people handle server errors with flash remoting? var responder = new Responder( function() { trace("some normal execution finished successfully. this is fine."); }, function(e) { trace("how do I make this trigger when my server tells me something bad happened?"); } ); myService = new NetConnection; myService.connect("http://localhost:88/amfphp/gateway.php"); myService.call("someclass.someservice", responder);

  • How many javascript link I can have in Facebook?

    Is there a limit of how many js file I can include () in facebook? I include 5 files. no problem.. the 6th one not loaded. Then I have to put the code in the 6th one into the 5th file. then works. so, is it 5 files in max? BY THE WAY, I'm developing the apps now, not in production. so it is not in the stage of compressing JS / minizing it. :) so it is kinda annoying to got missing js files or files not loaded..etc so, what is the limit from FB? what is the file size limit? I know that the JSON request call back data limit is 5000.. but not sure about the js include.

  • try/catch: errors or exceptions?

    - by Josh
    OK. I may be splitting hairs here, but my code isn't consistent and I'd like to make it so. But before I do, I want to make sure I'm going the right way. In practice this doesn't matter, but this has been bothering me for a while so I figured I'd ask my peers... Every time I use a try... catch statement, in the catch block I always log a message to my internal console. However my log messages are not consistent. They either look like: catch(err) { DFTools.console.log("someMethod caught an error: ",err.message); ... or: catch(ex) { DFTools.console.log("someMethod caught an exception: ",ex.message); ... Obviously the code functions properly either way but it's starting to bother me that I sometimes refer to "errors" and sometimes to "exceptions". Like I said, maybe I'm splitting hairs but which is the proper terminology? "Exception", or "Error"?

  • Setting a session variable in Global.asax causes AJAX errors

    - by Fly_Trap
    I'm getting a very peculiar problem with my asp.net application, it took me an age to track down but I still don't know what is causing this behaviour. If I set a session variable in the Application_PreRequestHandlerExecute event, then my external JavaScript files are ignored, and therfore causing a raft of errors. I have simplified the problem below. E.g. I have file called JScript.js containing the code: function myAlert() { alert("Hi World"); } And in my Default.aspx file I reference the js with the code: <script src="JScript.js" type="text/javascript"></script> And in the body onload event I call the myAlert() function: <body onload="myAlert()"> And finally in the Global.asax file: Private Sub Application_PreRequestHandlerExecute(ByVal sender As Object, ByVal e As EventArgs) HttpContext.Current.Session("myVar") = "MyValue" End Sub If you run the Default.aspx file you will see the js function isnt called, however, if you comment out the line of code Global.asax then the external js is called and the function executed when the page loads. Why is this?
