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. --- src/AudioIO.cpp | 17 ++++++++++++++++- 1 file changed, 16 insertions(+), 1 deletion(-) diff --git a/src/AudioIO.cpp b/src/AudioIO.cpp index a78bd1cab..d5481838d 100644 --- a/src/AudioIO.cpp +++ b/src/AudioIO.cpp @@ -452,8 +452,23 @@ writing audio. #define ROUND(x) (int) ((x)+0.5) //#include #include "../lib-src/portmidi/pm_common/portmidi.h" - #include "../lib-src/portaudio-v19/src/common/pa_util.h" #include "NoteTrack.h" + +PaTime PaUtil_GetTime( void ) +{ +#ifdef HAVE_MACH_ABSOLUTE_TIME + return mach_absolute_time() * machSecondsConversionScaler_; +#elif defined(HAVE_CLOCK_GETTIME) + struct timespec tp; + clock_gettime(CLOCK_REALTIME, &tp); + return (PaTime)(tp.tv_sec + tp.tv_nsec * 1e-9); +#else + struct timeval tv; + gettimeofday( &tv, NULL ); + return (PaTime) tv.tv_usec * 1e-6 + tv.tv_sec; +#endif +} + #endif #ifdef EXPERIMENTAL_AUTOMATED_INPUT_LEVEL_ADJUSTMENT -- 2.15.0 'left'>AgeCommit message (Expand)Author
