Hello, As part of the PyAV project (FFmpeg library bindings for Python) I produce builds of FFmpeg and its dependencies for Linux, macOS and Windows (using mingw):
https://github.com/pyav-org/pyav-ffmpeg Our builds recently started failing for libvpx on Windows with the following error: C:/msys64/mingw64/include/semaphore.h: In function 'sem_timedwait': C:/msys64/mingw64/include/semaphore.h:53:32: error: passing argument 2 of 'sem_timedwait64' from incompatible pointer type [-Wincompatible-pointer-types] 53 | return sem_timedwait64 (sem, (const struct _timespec64 *) t); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | | | const struct _timespec64 * C:/msys64/mingw64/include/semaphore.h:47:75: note: expected 'const struct _timespec64 *' but argument is of type 'const struct _timespec64 *' 47 | WINPTHREAD_API int sem_timedwait64(sem_t * sem, const struct _timespec64 *t); | ~~~~~~~~~~~~~~~~~~~~~~~~~~^ make[1]: *** [Makefile:176: vp8/vp8_cx_iface.c.o] Error 1 In file included from D:/a/pyav-ffmpeg/pyav-ffmpeg/build/vpx/vp8/common/threading.h:76, from D:/a/pyav-ffmpeg/pyav-ffmpeg/build/vpx/vp8/encoder/onyx_int.h:26, from D:/a/pyav-ffmpeg/pyav-ffmpeg/build/vpx/vp8/encoder/encodemv.h:14, from D:/a/pyav-ffmpeg/pyav-ffmpeg/build/vpx/vp8/encoder/bitstream.c:12: C:/msys64/mingw64/include/semaphore.h: In function 'sem_timedwait': C:/msys64/mingw64/include/semaphore.h:53:32: error: passing argument 2 of 'sem_timedwait64' from incompatible pointer type [-Wincompatible-pointer-types] 53 | return sem_timedwait64 (sem, (const struct _timespec64 *) t); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | | | const struct _timespec64 * C:/msys64/mingw64/include/semaphore.h:47:75: note: expected 'const struct _timespec64 *' but argument is of type 'const struct _timespec64 *' 47 | WINPTHREAD_API int sem_timedwait64(sem_t * sem, const struct _timespec64 *t); I cannot understand the error, because the "expected" and "actual" arguments seem to be identical?! I am wondering if this is a side effect of the changes discussed here: https://sourceforge.net/p/mingw-w64/mailman/message/59175709/ Many thanks in advance, Jeremy _______________________________________________ Mingw-w64-public mailing list Mingw-w64-public@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mingw-w64-public
