  • New to Linux Kernel/Driver development...

    - by CVS-2600Hertz-wordpress-com
    Recently, i began developing a driver of an embedded device running linux. Until now i have only read about linux internals. Having no prior experience in driver devlopment, i am finding it a tad difficult to land my first step. I have downloaded the kernel source-code (v2.6.32). I have read (skimped) Linux Device Drivers (3e) I read a few related posts here on StackOverflow. I understand that linux has a "monolithic" approach. I have built kernel (included existing driver in menuconfig etc.) I know the basics of kconfig and makefile files so that should not be a problem. Can someone describe the structure (i.e. the inter-links) of the various folders in the kernel-source code. In other words given a source-code file, which other files would it refer to for related code (The "#include"-s provide a partial idea) Could someone please help me in getting a better idea? Any help will be greatly appreciated Thank You.

  • Regex not operator

    - by Erik Goens
    I need to use a regex to pull a value out a url domain that will exclude everything but the host (ex: wordpress) and domain type (ex .com). The urls are dynamic and contain 2-3 values for each result (www.example.com or example.org). I am trying to use this expression, but I am only getting back the first letter of every item I am attempting to exclude: Expresssion (?!wordpress|com|www)(\w+|\d+) String example.wordpress.com Results example ordpress om Desired Result example Any assistance would be greatly appreciated

  • Timing the Linux Kernel boot-time optimisation

    - by CVS-2600Hertz-wordpress-com
    I am trying to optimise the boot-up time of linux on an embedded device (not PC) Currently to profile the boot-up sequence, I have enabled the timing info on printk logs. Is this the most optimum way? If not, how do i profile the boot-up sequence (with timing) with minimum overhead? PS: I have a terminal (of the device) over a serial-connection & I use TeraTerm over windows-XP to access it.

  • Many RewriteBase in one .htaccess file?

    - by Martti Laine
    Hello I have a domain and a wordpress-blog on same server. Now I have a problem (surprise). The wordpress is located on /httpdocs/blog/ and domain is pointing to /httpdocs/ and I'm trying to redirect it to /httpdocs/domain/. But, obvisiously, I have permalinks in Wordpress. Here's my current .htaccess: RewriteEngine On RewriteBase /blog/ RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /blog/index.php [L] RewriteBase / RewriteCond %{HTTP_HOST} domain.com RewriteCond %{REQUEST_URI} !^/domain RewriteCond %{REQUEST_URI} !^/cgi-bin RewriteRule ^(.*)$ domain/$1 [L] But as you already propably assumed, this doesn't work. Wordpress' permalinks affects to /domain/ also, so my images and other urls go wrong. Any advice? Is it possible to use RewriteBase like this? Martti Laine

  • dlopen / dlsym with as little linking as possible

    - by johannes
    I have an application which can make use of plugins which are loaded at runtime using dlopen. Each of the plugins defines a function toretrieve the plugin information which is defined using a common structure. Something like that: struct plugin { char *name; char *app_version; int app_verion_id; char *plugin_version; int plugin_version_id; /* ... */ }; struct plugin p = { "sample plugin",APP_VERION,APP_VERSION_ID,"1.2.3",10203 }; struct plugin *get_plugin() { return &p; } This works well and plugins can be loaded. Now i want to build a small tool to read these properties without linking the whole application. For doing that I have some code like this: void *handle; struct plugin *plugin; struct plugin *(get_plugin*)(); handle = dlopen(filename, RTLD_LAZY); if (!handle) { /*...return; ...*/ } get_plugin = dlym(handle, "get_plugin"); if (!get_plugin) { /*...return; ...*/ } plugin = get_plugin(); printf("Plugin: %s\n", plugin->name); This works nice for simple plugins. The issue is that many plugins reference further symbols from the application, which are resolved even though RTLD_LAZY was set. (like global variables from the application which are used to initialize plugin-global things) So the dlopen() call fails with an error like fatal: relocation error: file sample_plugin.so: symbol application_some_symbol: referenced symbol not found. As I just want to have access to the single simple structure I was wondering how I can prevent the linker from doing that much of his work.

  • Tiny MCE ImageManager Plugin, "cant create instance of plugin"

    - by Lofving
    We just bought MCImageManager and went right on to creating our own plugin. I followed http://wiki.moxiecode.com/index.php/MCI … ing_plugin from start to end but got stuck on the last step. After configuring the build.bat file (that comes along the package) it gives me no errors, i checked all paths and it should work but there just is no plugin.dll file anywhere to be found. (The bat file is also linked to the .net 1.4322, that should be changed by you at tinyMCE in my opinion) To circumvent that problem I started a new project and compiled the plugin.dll through Visual Studio. Then placed the dll in the c:..\project\plugins\plugin\bin\ folder (at the same place as the _TemplatePlugin.dll file but with the plugins name) All i get from running the application is "Could not create instance of plugin class: Moxiecode.Manager.Plugins.Plugin" What is it I'm missing? All the other plugins ain't giving this error and they follow the same structure as my custom plugin. Thanks in advance //Micael

  • accessing a static property via COM

    - by joreg
    is it possible to access a static property of a COM object without creating an instance of the object? my situation is this: i have an unmanaged application (written in delphi). this application exposes a COM-based plugininterface. until now i only wrote managed plugins in c#. plugins provide their info (name, author, ..) via a static property that returns an instance of PluginInfo (which implements IPluginInfo). this static property i can access on the managed plugins using http://managedvcl.com. now i want to write unmanaged plugins on the same interface. i can load them using: plug := CreateComObject(TGuid) as IMyPlugInterface; and they run, but i don't know how to read out their PluginInfo. so the question again is: is there another way than implementing IPluginInfo in the plugin-class and only accessing the info after i have created an instance of the plugin?

  • Eclipse does not start on Windows 7

    Suddenly Eclipse today has decides to stop working. The last thing I did was close all perspectives and close Eclipse. When loading eclipse from the command prompt, using: "eclipse.exe -clean" the splash screen loads for a split second then exits.

  • Installing sfJqueryTreeDoctrineManagerPlugin to Symfony 1.4

    - by Christine Q.
    I have faced serious difficulties while installing sfJqueryTreeDoctrineManagerPlugin to Symfony 1.4 w/ Doctrine ORM. The installation directly from the server did not work out like with previous plugins that I have installed: C:\pathsymfony plugin:install sfJqueryTreeDoctrineManagerPlugin plugin installing plugin "sfJqueryTreeDoctrineManagerPlugin" No release available for plugin "sfJqueryTreeDoctrineManagerPlugin" This is why I needed to install the plugin by downloading the tgz-archive and install it manually like this: C:\pathsymfony plugin:install "C:\path\to\downloads\sfJqueryTreeDoctrineManagerPlugin-1.2.4.tgz" plugin installing plugin "C:\path\to\downloads\sfJqueryTreeDoctrineManagerPlugin-1.2.4.tgz" sfSymfonyPluginManager Installing web data for plugin I guess everything should be fine this far? After that I edited \apps\admin\config\settings.yml like instructed in the plugins readme file. all: .settings: enabled_modules: [default, sfJqueryTreeDoctrineManager] I also checked that the plugin was enabled in \config\ProjectConfiguration.class.php like this: $this->enablePlugins(array( // other plugins, 'sfJqueryTreeDoctrineManagerPlugin' )); I published assets and cleared cache: C:\pathsymfony plugin:publish-assets >> plugin Configuring plugin - sfJqueryTreeDoctrineManagerPlugin C:\pathsymfony cc Finally I added the required helper to the newly created apps\admin\modules\category\templates\indexSuccess.php <?php use_helper("sfJqueryTreeDoctrine"); echo get_nested_set_manager("Category", "name"); When loading the page I unfortunately get the following error: 500 | Internal Server Error | InvalidArgumentException Unable to load "sfJqueryTreeDoctrineHelper.php" helper in: SF_ROOT_DIR\apps\admin\modules/businessunitgroup/lib/helper, SF_ROOT_DIR\apps\admin\lib/helper, SF_ROOT_DIR\lib/helper, SF_SYMFONY_LIB_DIR/helper. The file sfJqueryTreeDoctrineHelper.php exists indeed but not in any previously mentioned folder. The file can only be found in the folder \plugins\sfJqueryTreeDoctrineManagerPlugin\lib\helper. I guess that Symfony doesn't look to that folder while finding helpers? I have tried to move the helper file to one of the previously mentioned folders. As expected, that changes the error. Now I get: 500 | Internal Server Error | sfConfigurationException The component does not exist: "sfJqueryTreeDoctrineManager", "manager". Unfortunately I can't figure out how should I be able to retrieve the "missing" component from the correct folder. I would be very grateful for any advice to help me forward. By the way, I am aware that there are other nested-set / tree plugins available for Symfony (like sfDoctrineTreePlugin and caPropelTreePlugin) but unluckily those are either uncompatible or too limited for my needs.

  • Paperclip: delete attachment and "can't convert nil into String" error

  • Standalone XULRunner app not loading the Flash player plugin

    - by Rajeesh
    Hi, I have created a standalone XUL application, and I copied "NPSWF32.dll"(flash plugin dll) to the "plugins" folder under the browser. When I launch the application, flash content is not getting displayed. If I set the MOZ_PLUGIN_PATH to the "plugins" directory before launching the application, everything is working as expected. Could someone tell me, what I needs to do in order to load the flash plugin automatically from the "plugins" folder. Thanks, Rajeesh

    I'm looking for a CMS just for backend that lets you manage database tables with custom fields. I found Wordpress Pods similar to what I'm looking for, but I don't want Wordpress to manage my frontend (and Wordpress Pods don't look professional to me...) Is there something like this out there? Thank you. Sergio

  • jQuery working in everything but IE7. (checked my commas)

    - by deadlyhifi
    The following code works in IE8, FF, Safari, Chrome etc. (not bothering with IE6 for this one), but doesn't work in IE7. I've been through the code with a fine tooth-comb. Checked the commas, messed around with ; but it's not going anywhere. I'm using the jQuery Validate and Uploadify scripts. Can anyone see the problem here? Thanks. <script type="text/javascript"> jQuery(document).ready(function($) { $("#validateform").validate({ errorClass: 'invalid', rules: { bike_url: { required: true, url: true } } }) $("#uploadify").uploadify({ 'uploader' : '<?php echo $url .

  • Require-Bundle and Import-Package versus feature.xml requires

    - by Robert Munteanu
    When building an Eclipse plugin (lato sensu) which consists of multiple plugins and one feature, I have two ways of specifying dependencies: in the plugins themselves, using Require-Bundle and Import-Package in META-INF/MANIFEST.MF; in the feature.xml file from the feature. In my understanding, it should be enough to declare the dependencies at the lower level, i.e. in the plugins. Why do we still have the feature.xml requires mechanism?

  • RANDOM Number Generation in C

    - by CVS-2600Hertz-wordpress-com
    Recently i have begun development of a simple game. It is improved version of an earlier version that i had developed. Large part of the game's success depends on Random number generation in different modes: MODE1 - Truly Random mode myRand(min,max,mode=1); Should return me a random integer b/w min & max. MODE2 - Pseudo Random : Token out of a bag mode myRand(min,max,mode=2); Should return me a random integer b/w min & max. Also should internally keep track of the values returned and must not return the same value again until all the other values are returned atleast once. MODE3 - Pseudo Random : Human mode myRand(min,max,mode=3); Should return me a random integer b/w min & max. The randomisation ought to be not purely mathematically random, rather random as user perceive it. How Humans see RANDOM. * Assume the code is time-critical (i.e. any performance optimisations are welcome) * Pseudo-code will do but an implementation in C is what i'm looking for. * Please keep it simple. A single function should be sufficient (thats what i'm looking for) Thank You

  • Unable to disable generation of sources JAR with maven-release-plugin

    - by Chris Lieb
    I am trying to release a web project using Maven 2.2.1 and the maven-release-plugin 2.0-beta-9, but it always fails when doing release:perform on generating the sources jar for the EAR project, which makes sense since the EAR project doesn't have any source. [INFO] [INFO] [source:jar {execution: attach-sources}] [INFO] [INFO] ------------------------------------------------------------------------ [INFO] [ERROR] BUILD ERROR [INFO] [INFO] ------------------------------------------------------------------------ [INFO] [INFO] Error creating source archive: You must set at least one file. To try to disable the building of a sources JAR for the EAR project, I added the following to the POM for my EAR project (the version of the release plugin is set in a parent POM): <build> <plugins> ... <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-release-plugin</artifactId> <configuration> <useReleaseProfile>false</useReleaseProfile> </configuration> </plugin> </plugins> </build> Upon running the release again after checking in this change, I got the same error while generating the sources JAR for the EAR project, even though this should have been disabled by the previous POM snippet. What am I doing wrong? Why is the sources JAR still being built? Edit: I've tried to make the source plugin include my application.xml file so that this error doesn't occur by adding the following POM snippet: <build> <plugins> ... <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-source-plugin</artifactId> <configuration> <includes> <include>${basedir}/META-INF/**/*</include> </includes> <useDefaultExcludes>false</useDefaultExcludes> </configuration> </plugin> </plugins> </build> Unfortunately, this does not fix the problem either.

  • Can an interface define the signature of a c#-constructor

    - by happyclicker
    I have a .net-app that provides a mechanism to extend the app with plugins. Each plugin must implement a plugin-interface and must provide furthermore a constructor that receives one parameter (a resource context). During the instantiation of the plugin-class I look via reflection, if the needed constructor exists and if yes, I instantiate the class (via Reflection). If the constructor does not exists, I throw an exception that says that the plugin not could be created, because the desired constructor is not available. My question is, if there is a way to declare the signature of a constructor in the plugin-interface so that everyone that implements the plugin-interface must also provide a constructor with the desired signature. This would ease the creation of plugins. I don’t think that such a possibility exists because I think such a feature falls not in the main purpose for what interfaces were designed for but perhaps someone knows a statement that does this, something like: public interface IPlugin { ctor(IResourceContext resourceContext); int AnotherPluginFunction(); } I want to add that I don't want to change the constructor to be parameterless and then set the resource-context through a property, because this will make the creation of plugins much more complicated. The persons that write plugins are not persons with deep programming experience. The plugins are used to calculate statistical data that will be visualized by the app.

  • How to register a function in a driver code as its ISR

    - by CVS-2600Hertz-wordpress-com
    Following the feedback i got from: http://stackoverflow.com/questions/2683682/new-to-linux-kernel-driver-development/2683819 I have written a driver (.c file) by comparing it with an existing driver and "borrowing" heavily from its code. The driver is registered fine and init() and probe() are working fine. I am also able to access the peripheral device registers. :-) However i am a bit hazy about the IRQ/ISR. The peripheral-device is a input device and raises an interrupt on a GPIO pin. How do i move ahead from my current state ( init(), probe(), etc. ) to be able to handle the IRQ and execute my ISR function?? Many-Thanks in Advance

  • Get instance of type inheriting from base class, implementing interface, using StructureMap

    - by Ben
    Continuing on my quest for a good plugin implementation I have been testing the StructureMap assembly scanning features. All plugins will inherit from abstract class PluginBase. This will provide access to common application services such as logging. Depending on it's function, each plugin may then implement additional interfaces, for example, IStartUpTask. I am initializing my plugins like so: Scan(x => { x.AssembliesFromPath(HttpContext.Current.Server.MapPath("~/Plugins"), assembly => assembly.GetName().Name.Contains("Extension")); x.AddAllTypesOf<PluginBase>(); }); The difficulty I am then having is how to work against the interface (not the PluginBase) in code. It's easy enough to work with PluginBase: var plugins = ObjectFactory.GetAllInstances<PluginBase>(); foreach (var plugin in plugins) { } But specific functionality (e.g. IStartUpTask.RunTask) is tied to the interface, not the base class. I appreciate this may not be specific to structuremap (perhaps more a question of reflection). Thanks, Ben

  • Munin Mongodb Plugin Not Showing. . . ?

    - by alfredo
    I have installed munin and munin-node on my monitoring server and installed munin-node on my mongodb server, I have set them both up and all is working great. But, the mongodb plugins aren't showing on my monitoring server. I see the node listed and "Disk, Network, Processes, System", but not the mongo stuff. If I execute one of the plugins directly on the mongo server "python /usr/share/munin/plugins/mongo_btree" it returns output, but nothing shows on the monitoring server.
