Bug 116356 – mjpegtools-1.8.0-r1 doesn't set CFLAGS correctly

• Product: Gentoo Linux
• Status: RESOLVED WORKSFORME

[Description Sebastian 2005-12-21 23:56:51 UTC]

Hi!

I updated to mjpegtools-1.8.0-r1 today. The merge went fine, but the CFLAGS are off. I get warnings (`-mcpu=' is deprecated. Use `-mtune=' or '-march=' instead.') even though I don't use 'mcpu'. Maybe the mjpegtools Makefile has changed?

 i586-pc-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I../.. -I../../utils -march=i586 -mcpu=i586 -Os -march=i586 -m3dnow -mmmx -pipe -fomit-frame-pointer -mno-sse2 -pthread -Wall -Wunused -MT build_sub22_mests.lo -MD -MP -MF .deps/build_sub22_mests.Tpo -c build_sub22_mests.c  -fPIC -DPIC -o .libs/build_sub22_mests.o
`-mcpu=' is deprecated. Use `-mtune=' or '-march=' instead.

Innocent warning that does not break anything. Ask upstream to fix it if you really care.

Hi!

Yes, I see your point. But shouldn't the ebuild take care of setting the wanted CFLAGS? Don't we specify CFLAGS for that in make.conf. There're hundreds of ebuilds out there that even patch things so that the CFLAGS in make.conf are used.

I think the ebuild should take care of this. You can't totally rely on upstream. That's why there are so many patches in portage.

Thanks

Sebastian

Just to clear it up. I want '-Os -march=i586 -m3dnow -mmmx -pipe -fomit-frame-pointer' and not '-march=i586 -mcpu=i586 -Os -march=i586 -m3dnow -mmmx -pipe -fomit-frame-pointer'.

Your CFLAGS aren't used? How so? How's -march=i586 -mcpu=i586 different from just march=i586? Once again, this is a compiler warning that does not break/harm anything.

Hi!

I had a look at the 'configure' script. I think it'd take me some time to make changes so it runs the way I'd like it to. Time I haven't got at the moment. So nevermind for now.

Cheers
