-Subject: [PATCH] Fix building against the system portaudio library
-
-Building against the system portaudio results in this error:
-
-./src/AudioIO.cpp:983: undefined reference to `PaUtil_GetTime'
-audacity-AudioIO.o: In function `audacityAudioCallback(void const*, void*,
-unsigned long, PaStreamCallbackTimeInfo const*, unsigned long, void*)':
-./src/AudioIO.cpp:4630: undefined reference to `PaUtil_GetTime'
-collect2: error: ld returned 1 exit status
-Makefile:2349: recipe for target 'audacity' failed
-make[3]: *** [audacity] Error 1
-
-This is because PaUtil_GetTime is declared as a C symbol in pa_util.h
-but is resolved as a C++ symbol at link time.
-
-Audacity fixes this in the local tree with this change:
-https://github.com/audacity/audacity/commit/38fd97b8e26060332ab3e9e000a8882326a70ba7
-
-However this is not general enough for the portaudio debian package.
-
-Since PaUtil_GetTime() is the only function causing problems, just copy
-over the code where it's used.
