Hi, I think I was able to remove the -wN flag warning on OSX, but then a new
error popped out:
YASM libavcodec/x86/h264_deblock_10bit.o
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/strip:
symbols referenced by relocation entries that can't be stripped in:
libav/libavcodec/x86/h264_deblock_10bit.o
_ff_pw_4
pw_pixel_max
_ff_pw_2
_ff_pw_3
Searching for that error results in a reference to osx's strip manpage that
says:
strip no longer removes relocation entries under any condition. Instead, it
updates the external relocation entries (and indirect symbol table entries) to
reflect the resulting symbol table. strip prints an error message for those
symbols not in the resulting symbol table that are needed by an external
relocation entry or an indirect symbol table. The link editor ld(1) is the only
program that can strip relocation entries and know if it is safe to do so.
I intuitevely added the -x option which apparently fixed this for me, although
it might alter the original intent of the -wN flags completely. Maybe the right
way would be not to use strip at all on OSX?
Any suggestion is welcome.
