Author: Steve Lhomme <[email protected]> Committer: Diego Biurrun <[email protected]> Date: Thu Dec 15 18:00:56 2016 +0100 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. --- configure | 1 + 1 file changed, 1 insertion(+) diff --git a/configure b/configure index 25640eb..2ecd0ed 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 _______________________________________________ libav-commits mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-commits
