[solved] CFLAGS and freeglut problem

decken · Last edited by decken on Thu Jul 19, 2007 4:57 am; edited 1 time in total

I just tried installing gentoo for the first time on stage3. Everything seems fine, except when I tried to emerge xorg-x11, it stopped on freeglut, saying I should change from mcpu to march in my CFLAGS. So, I did, but it keeps giving me the same error message about march not being specified. I've tried env-update, and emerge -eD freeglut, like some other posts I read about people with the same problem, but nothing seems to change. I'm also not entirely sure I've got it specified correctly for my CPU, which I can't find listed anywhere.

cat /proc/cpuinfo:
processor :0
Vendor ID : CyrixInstead
CPU family : 6
model : 2
model name : MII 2.5x Core/Bus Clock
Stepping : 4
cpu MHz : 250.079
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_extention : yes
cpuid level : 1
wp : yes
flags : fpu de tsc msr cx8 pge cmov mmx cyrix_arr up
bogomips : 500.74
cl flush size : 32

My CFLAGS are currently:
CFLAGS="-march=i486 -O2 -pipe -fomit-frame-pointer"

Thanks for any help you can offer.

how about setting CFLAGS to:

I tried that before too, but that's for the Cyrix MediaGX and mine's the Cyrix MII, which is slightly slower. I've tried it as a couple of things, but I always get the same error message that "mcpu is deprecated, try march isntead" or something along those lines. So it seems like the problem is that it's just not picking up on changes at all.

Could you please post those lines, including previous and following lines, maybe there's a hint around that error.
Please include the output of

You could also try mtune and see if that fixes anything. If it STILL spits out an error, then there is a good chance its jus not picking anything up (as seems to be the case anyways)

I just asked to post the output of "emerge --info" to see, that gentoo is setting the variable correctly,
it could be that there are any escaped characters that are not resolved correctly.

Weird, so it looks like it doesn't match my /etc/make.conf... Also, in /etc/make.conf it says my CHOST is i486, but this says i686?

What editor are you using? Try use vi (or vim). Maybe yours is setting windows escape character, which make portage not to read the make.conf line.
