  • Porting a C++ application to android

    - by vivekian2
    Is it possible to port a C++ application which uses the STL extensively to Android? I understand that currently the NDK does not support this, but is there any effort (open source or otherwise) underway to achieve this? If not is there a way to cross compile libstdc++ for Android?

  • Using CATransition in a viewController

    - by eco_bach
    Hi I'm trying to implement the ViewTransitions code sample from Apple, but putting all the logic in my viewController instead of my applicationDelegate class. I'm getting a bizarre error when I try to compile. I'm importing QuartzCore in my viewcontroller implementation as #import _kCATransitionFade", referenced from: _kCATransitionFade$non_lazy_ptr in ViewTransitionsAsViewControllerViewController.o (maybe you meant: _kCATransitionFade$non_lazy_ptr) Anyone have any ideas?

  • python webbrowser.open(url)

    - by Gert Cuykens
    httpd = make_server('', 80, server) webbrowser.open(url) httpd.serve_forever() This works cross platform except when I launch it on a putty ssh terminal. How can i trick the console in opening the w3m browser in a separate process so it can continue to launch the server? Or if it is not possible to skip webbrowser.open when running on a shell without x?

  • WCF XmlSerializer assembly not speeding up first request

    - by Matt Dearing
    I am generating proxy classes to a clients java webservice wsdls and xsd files with svcutil. The first call made to each service proxy class takes a very long time. I was hoping to speed this up by generating the XmlSerializers assembly myself (based on the article How to: Improve the Startup Time of WCF Client Applications using the XmlSerializer), but when I do the first call to each service still takes the same amount of time. Here are the steps I am following: //generate strong name key file sn -k Blah.snk //generate the proxy class file svcutil blah.wsdl blah2.wsdl blah3.wsdl ... base.xsd blah.xsd ... /UseSerializerForFaults /ser:XmlSerializer /n:*,SomeNamespace /out:Blah.cs //compile the class into an assembly signing it with the strong name key file csc /target:library /keyfile:Blah.snk /out:Blah.dll Blah.cs //generate the XmlSerializer code this will give us Blah.XmlSerializers.dll.cs svcutil /t:xmlSerializer Blah.dll //compile the xmlserializer code into its own dll using the same key to sign it and referencing the original dll csc /target:library /keyfile:Blah.snk /out:Blah.XmlSerializers.dll Blah.XmlSerializers.dll.cs /r:Blah.dll I then create a standard Console application that references both Blah.dll and Blah.XmlSerializers.dll. I will then try something like: //BlahProxy is one of the generated service proxy classes BlahProxy p = new BlahProxy(); //this call takes 30ish seconds p.SomeMethod(); BlahProxy p2 = new BlahProxy(); //this call takes < 1 second p2.SomeMethod(); //BlahProx2y is one of the generated service proxy classes BlahProxy2 p3 = new BlahProxy2(); //this call takes 30ish seconds p3.SomeMethod(); BlahProxy2 p4 = new BlahProxy2(); //this call takes < 1 second p4.SomeMethod(); I know that the problem is not server side because I don't see the request made in Fiddler until around 29 seconds. Subsequent calls to each service take < 1 second, so thats why I was hoping the main slow down was the .net runtime generating the xmlserializer code itself, compiling it and loading the assembly. I figured this would be the reason the first call to each service is slow and the rest are fast. Unfortunatley, me generating the code myself is not speeding anything up. Does anyone see what I am doing wrong?

    IAR C/C++ Compiler for MSP430 5.10.1 [Evaluation] (5.10.1.20144) I get an illegal state internal error when attempting to compile the FreeRTOS 5.4 Task.c file (everything else compiles fine) Internal Error: [CoreUtil/General]: Illegal state The kick start version of IAR (MSP430 version) works fine. Any thoughts?

  • Why is C++0x's `noexcept` checked dynamically?

    - by rlbond
    I am curious about the rationale behind noexcept in the C++0x FCD. throw(X) was depreciated, but noexcept seems to do the same thing. Is there a reason that noexcept isn't checked at compile time? It seems that it would be better if these functions were checked statically that they only called throwing functions within a try block.

  • C++ Linker Error SDL Image - could not read symbols

    - by Matt H
    Hi, I'm trying to use the SDL_Image library and I've added the .so to the link libraries list for my project (I'm using Code::Blocks, by the way). After doing this, when I go to compile, I get this error: Linking console executable: bin/Debug/ttfx /usr/lib32/libSDL_image-1.2.so: could not read symbols: File in wrong format What does this mean and how can I get it working? Thanks!

  • Postsharp duplicate attribute?

    - by yodaj007
    Can anyone explain why I'm getting this compile error? Duplicate 'Rad.Core.Aop.MethodArgumentValidation' attribute E:\Scripting\Rad.Core\Properties\AssemblyInfo.cs This is the code: [assembly: Rad.Core.Aop.MethodArgumentValidation(AttributeTargetTypes="Rad.*", AttributePriority=1)] [assembly: Rad.Core.Aop.MethodArgumentValidation(AttributeTargetTypes = "Rad.Core.Aop.*", AttributePriority = 2, AttributeExclude=true)] Here is the declaration of the aspect: [Serializable] [AttributeUsage(AttributeTargets.Assembly | AttributeTargets.Class | AttributeTargets.Method | AttributeTargets.Property)] [MulticastAttributeUsage(MulticastTargets.Method, AllowMultiple=true)] public class MethodArgumentValidationAttribute : OnMethodInvocationAspect { ... } It looks like I'm following this example: http://www.sharpcrafters.com/blog/post/multicasting-of-custom-attributes.aspx Can anyone help?

  • ActionScript 3 and camelcase package name

    - by Paul Dinh
    I'm using Flash Builder 4 to build my AIR application. For a certain reason, I need to declare my package name in camelcase, and class names in lowercase: //test.as package Core { public class test { } } The folder structure is like this (the dir 'Core' matches the package name): src/ Core/ test.as However, Flash Builder shows error and it doesn't compile at all, only when I put the package name as 'core' then it compiles. Does AS3 syntax allow uppercase letters in package name? Or just because Flash Builder implicitly disallows this?

  • Matching sentences with regex in Java

    - by Gary
    Hi, I'm using the Scanner class in java to go through a a text file and extract each sentence. I'm using the setDelimiter method on my Scanner to the regex: Pattern.compile("[\\w]*[\\.|?|!][\\s]") This currently seems to work, but it leaves the whitespace at the end of the sentence. Is there an easy way to match the whitespace at the end but not include it in the result? I realize this is probably an easy question but I've never used regex before so go easy :)

  • Opt-out of copy constructor

    - by sheepsimulator
    This might be a silly question, but... I've been writing a number of classes that utilize non-copyable members. These classes are never initialized via the copy constructor in my source. When I try to compile without supplying my own copy-constructor, g++ throws out many errors about how it can't build a default copy constructor, due to the non-copyable member objects. Is there a way to tell the compiler to just not give me a copy constructor?

  • Usb Driver on 64bit Windows

    - by SurDin
    I have a pretty generic 64bit driver based on bulkusb.sys in WDK. It's been working for years with an embedded program, but now it is needed to work on Vista 64. From all the documentation I've tried to look through there doesn't seem to be anything affecting it, except compiling it for the 64bit environment, and yet when I compile it with the AMD64 build environment, I get "driver not intended for this platform" error message when it's trying to open the sys. What could be the solution for this?

  • Calls to singleton library

    - by metdos
    I have a singleton class, and I will compile it as a library static(lib) or dynamic(dll). Is it guaranteed that calls to same file in a machine always refer to same and unique instance in both cases?

    - by Alex
    I'm trying to compile my project including route-me using armv7 although am struggling with the following error, i have older versions of the same project in git which compiles fine with armv7 so a setting must have changed somewhere to break it, here is the error: Undefined symbols for architecture armv7: "_pj_fwd", referenced from: -[RMProjection latLongToPoint:] in libMapView.a(RMProjection.o) "_pj_inv", referenced from: -[RMProjection pointToLatLong:] in libMapView.a(RMProjection.o) "_pj_init_plus", referenced from: -[RMProjection initWithString:InBounds:] in libMapView.a(RMProjection.o) "_pj_free", referenced from: -[RMProjection dealloc] in libMapView.a(RMProjection.o) ld: symbol(s) not found for architecture armv7 clang: error: linker command failed with exit code 1 (use -v to see invocation) Any help would be greatly appreciated.

  • an emacs command to open a new instance of emacs

    - by RamyenHead
    How can I make a cross-platform emacs command that opens another instance of emacs with -q option? The reason why I need such a command is that it would be easy to modify the command to make it open another instance of emacs with -q and -l option so that the new instance loads an el file that I am editing with the old instance.

  • Minimalistic tools for developer documentation

    - by Pekka
    I am currently working on a large PHP CMS / Framework and documenting it extensively as I go along. In addition to phpdoc-style inline comments, I need to document XML structures, details on concepts and practices, write HOWTOs and so on. At the moment, I am using simple OpenOffice documents for that, but I'm unhappy with it and looking for a "real" documentation system. So, I am looking for recommendations for robust, minimalistic, easy-to-use documentation software. I have tried a number of Wikis, most prominently Dokuwiki. I like the open-minded approach, the freedom in editing, and the simplicity, but they provide little support in structuring a multi-chapter documentation, and make basic reorganisation tasks very difficult (e.g. moving pages to a different namespace). Working with the plugins is Cumbersome, and they are not really easy to use. Open Source would be a plus but is not a requirement. Thanks for all the suggestions. I have not had time to look into each one in detail. I will be trying Sphinx, especially because it provides so much support for a good structure. I may update this post later when I'm done and report how it worked out. The suggestions Trac's built-in wiki which is great but for my taste provides too little support for keeping a structure - it's perfect though for "normal", smaller size project documentation Markdown my current favourite because of its minimalism, however not sure yet whether maintaining a structure will be easy enough. A Markdown-Based system would of course be very easy to extend, e.g. to look up cross references from the project's code base. Of course it would be great to find something that already has that out of the box. The DocBook format and to edit, the commercial Oxygen XML Editor - a great standard for building documentation, no doubt. Maybe too "technical" for my purposes as I need something to open quickly, write into and go on coding. Still always worth a mention. Sphinx an Open Source, Python based documentation generator, promising structured documentation and extensive cross-referencing. Interesting and will take a look. Confluence a commercial but very affordable Wiki. XWiki, an Open Source playing in Confluence's league with numerous extensions and connectors to Eclipse and Microsoft Office. TiddlyWiki an open-source Wiki.
