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.
