[gentoo-user] freeglut

[Jean Magnan de Bornier]

Hi all, 
Trying to emerge -uD world, with xorg-x11-7.0-r1; a lot has been
done yet but I cannot emerge freeglut:

...............................................
boldair X11 # emerge -uDav world

These are the packages that would be merged, in order:

Calculating world dependencies... done!

I've seen several bugs on freeglut but it doesn't help me...
re-synced several times also.

Does your CFLAGS have -mfpmath=sse?  If so, take that out.  In fact,
-march=i686?  Are you running some ancient pentium?  Maybe you should
just post the output of "emerge --info" and "cat /proc/cpuinfo" for
review...

Done, it worked; any side-effects to fear?
Thx,

It should work fine, but I still suspect your -march setting is not
optimal.  What kind of processor are you using?

Yes, you guessed right again: it is a Dell latitude x1, and I followed the
howto of the gentoo-wiki, which says:

.....................................
If you use GCC <3.4.3, there is no pentium-m arch, you need to use
pentium3. Using GCC 3.4.3 or later, you might want to try
-march=pentium-m. Those CFLAGS are known to be safe:

CFLAGS="-O2 -march=pentium3 -pipe -mfpmath=sse"
CXXFLAGS="${CFLAGS}"
.....................................

But I had forgotten to make the change when switching to gcc-3.4. Now I
did it...
Thanks,
