Cannot open include file: 'pthread': No such file or directory

[cuinjune]

I tried building ofxPd using Visual Studio 2017 on Windows 10 but it fails with the following error:

Cannot open include file: 'pthread': No such file or directory

I followed every instructions in your README but I could not build it. (I tried on 32bit and 64bit) I could successfully build ofxPd last year using OF 0.9.8 but not this time with OF 0.10.1 on Windows.

I tried using both pd 0.48.2 and 0.49.0 (I tried building libpd based on each sources) I also put libwinpthread-1.dll inside project's bin folder but I don't know why pd's source files cannot include "pthread.h".

Do you have any idea how to fix this? Any advice would be appreciated!

Did OF stop including pthread with its sources for windows? In any case, you need to find where the header is and include a path to its folder in the header search paths.

If you don’t know what that means, read up on how to include libraries in C/C++ and Visual Studio.

I figured out how to build ofxPd using Visual Studio 2017 on Windows 10. I tested the following using pd-0.49.0.

1. Download pthreadVC2.lib and pthreadVC2.dll from https://sourceware.org/pub/pthreads-win32/dll-latest/ (x64 and x86 respectively)
2. Download and build libpd by following these steps https://github.com/danomatika/ofxPd#using-ofxpd-with-visual-studio and generate libpd.lib and pd.dll. (x64 and x86 respectively)
3. Put libpd.lib and pthreadVC2.lib inside your custom directories such as ofxPd\libs\libpd\lib\Win32 and ofxPd\libs\libpd\lib\Win64.
4. Put pd.dll, pthreadVC2.dll and libwinpthread-1.dll(find this from libpd\libs folder) inside yourProject\bin folder.
5. In your Visual Studio project, go to Debug -> Properties -> Linker -> Input section and add the custom paths like the following in Additional Dependencies:

   ..\..\..\addons\ofxPd\libs\libpd\lib\(Win32 or Win64)\libpd.lib
   ..\..\..\addons\ofxPd\libs\libpd\lib\(Win32 or Win64)\pthreadVC2.lib

6. Go to Debug -> Properties -> C/C++ -> Preprocessor section and add the followings in Preprocessor defines

   PD
   PD_INTERNAL
   HAVE_STRUCT_TIMESPEC

7. Make sure Debug -> Properties -> C/C++ -> Advanced -> Compile As is set to Default.
8. Go to Project -> Manage Nuget Packages, In browse Tab search for pthread then select Install[Search Results in Nuget packages].
9. Open x_vexp_fun.c from ofxPd\libs\libpd\pure-data\src and find the following code in line 540.

   #ifdef _MSC_VER
   /* rint is now advertised as part of the microsoft SDK but my MSVC still
   doesn't find it - so here it is again. */
   static double rint(double x)
   {
       return (floor(x + 0.5));
   }
   #endif

   Change the code to the following:

   #ifdef _WIN32
   #if _MSC_VER < 1900
   /* rint is now advertised as part of the microsoft SDK but my MSVC still
   doesn't find it - so here it is again. */
   static double rint(double x)
   {
       return (floor(x + 0.5));
   }
   #endif
   #endif

10. Open pd~.c from ofxPd\libs\libpd\pure-data\extra\pd~ and find the following code in line 29.

    #ifdef _MSC_VER
    #pragma warning (disable: 4305 4244)
    #define snprintf sprintf_s
    #define stat _stat
    #endif

    Change the code to the following:

    #ifdef _WIN32
    #if _MSC_VER < 1900
    #pragma warning (disable: 4305 4244)
    #define snprintf sprintf_s
    #define stat _stat
    #endif
    #endif

11. Now, build and run the project, everything should work fine.

This should be smoother as newer versions of the Pd source build much better within Visual Studio and info has been added about how to do this for ofxPd: https://github.com/danomatika/ofxPd#adding-libpd-to-a-visual-studio-project
