configure: fix linking with MSVC when using --disable-optimizations Without any optimization flags, MSVC does no dead code elimination (DCE) at all, even for the most trivial cases. DCE is a prerequisite for building libav correctly, otherwise there are undefined references to functions for other architectures and disabled components. -O1 is the minimal optimization flag for MSVC that does include DCE. > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=f7174d7ed045445d00a6d557236737d09ad32343 --- configure | 1 + 1 file changed, 1 insertion(+) diff --git a/configure b/configure index 25640ebb7f..2ecd0ed718 100755 --- a/configure +++ b/configure @@ -3279,6 +3279,7 @@ probe_cc(){ _DEPFLAGS='$(CPPFLAGS) $(CFLAGS) -showIncludes -Zs' _cflags_speed="-O2" _cflags_size="-O1" + _cflags_noopt="-O1" if $_cc -nologo- 2>&1 | grep -q Linker; then _ld_o='-out:$@' else _______________________________________________ ffmpeg-cvslog mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-cvslog
