Problem with mex compilation of Portaudio

Hi

I am trying to install the Playrec matlab software http://www.playrec.co.uk/compiling.html, which needs to compile the portaudio http://www.portaudio.com/download.html and ASIO SDK2.3 http://www.steinberg.net/en/company/developers.html libraries.

The code provided by the author of Playrec uses the function

Hi Dorian,

I had the exact same error. As Geoff says, the problem is that that the compiled pa_ringbuffer.c is not found by the linker. I found out that for whatever reason, compile_playrec_func.m does not set up the pa_common_files variable for Windows. So I added it. Starting at line 115 in compile_playrec_func.m, it now looks like this:

elseif is_os('WIN')
  compiler_flags = [compiler_flags, {'WIN32'}];
  link_libs = [link_libs, {'user32.lib', 'ole32.lib', ...
                           'advapi32.lib', 'winmm.lib'}];

    pa_os_specific_files = [pa_os_specific_files, ...
                            {'src/os/win/pa_win_hostapis.c',...
                            'src/os/win/pa_win_util.c',...
                            'src/os/win/pa_win_waveformat.c',...                            
                            'src/os/win/pa_x86_plain_converters.c'}];

    % add necessary c files to pa_common_files
    pa_common_files = [pa_common_files, ...
                       {'src/common/pa_ringbuffer.c', ...
                       'src/os/win/pa_win_coinitialize.c'}];

    if ~isempty(sdk_path)
       api_include_dirs = [api_include_dirs,...
[...]

As you can see, it turns out that pa_win_coinitialize.c is also needed.

HTH, Roman

[Geoff Hayes]

Dorian - according to the http://portaudio.com/docs/v19-doxydocs-dev/pa__ringbuffer_8c.html link, these unresolved links are to functions defined in the pa_ringbuffer.c file. Try adding it to your build arguments list as

 C:\Users\Asus\Desktop\playrec\lib\portaudio\src\common\pa_ringbuffer.c

only if the above path is valid (i.e. does this file exist at this location?). If you do have this file, then it will need to be compiled and linked into the build script.

I have now been trying to compile playrec on Windows 7 x64. Maybe my pain can avoid someone else's.

Software versions:

• Matlab 2013a
• two playrec versions, with READMEs from 2014-03-31 (Trial 1-3) and 2015-06-20 (Trial 4-6)
• portaudio pa_stable_v19_20140130
• Microsoft Visual C++ 2008 + Microsoft SDK for Windows 7
• Diect X: C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)
• ASIO: C:\Users\katzer\Matlab\ASIOSDK2.3
• Portaudio: C:\Users\katzer\Matlab\portaudio

Compiling with ASIO, Dirext X and WASAPI support.

Trial 1: >> compile_playrec

Undefined function 'exist' for input arguments of type 'cell'.

Error in compile_playrec_func (line 162)
        if exist(resolve_paths(dsound_path, {'lib/x64'}),'dir')

So I put a char() around the resolve_paths function.

Trial 2: (see trial2.txt)

So to get rid of unresolved dependencies I tried my fix form here that had worked before (see comment above at top of page)

      % add necessary c files to pa_common_files
      pa_common_files = [pa_common_files, ...
                         {'src/common/pa_ringbuffer.c', ...
                         'src/os/win/pa_win_coinitialize.c

Trial 3: (see trial3.txt)

Unfortunately, that didn't work either.  I got additional warnings (line 211):
C:\Users\katzer\AppData\Local\Temp\mex_KgCVoQ\pa_ringbuffer.obj : warning LNK4042: object specified more than once; extras ignored
C:\Users\katzer\AppData\Local\Temp\mex_KgCVoQ\pa_win_coinitialize.obj : warning LNK4042: object specified more than once; extras ignored

Trial 4: So now I remembered I hadn't had all those difficulties before. The unresolved symbols errors had looked differently, too. I copied the old playrec directory over from a different machine and tried the whole thing again.

>> compile_playrec
build_mex: Unable to find 'C:\Users\katzer\Matlab\portaudio\src\hostapi\wasapi\pa_win_wasapi.cpp'

Sure enough, it's not a cpp file but a c file.

Trial 5: Just renaming the file got me more errors, though (note I'm not a C/C++ developer): (see trial5.txt)

Trial 6: Edit compile_playrec_func.m to look for a c file instead of cpp:

          pa_api_specific_files = [pa_api_specific_files,...
                                   {'src/hostapi/wasapi/pa_win_wasapi.c'}]; % ROMAN: was cpp

That finally did the trick - it gave me a playrec.mexw64
