Blender 2.4x + Gentoo works bad on my box

AkhIL · Post by **AkhIL** » Mon Jan 30, 2006 4:28 am

At start blender takes 0.3 % of CPU. But after pressing Alt-A (play animation) and Esc (stop playing) Blender slows down and takes 20% of CPU time even scene is empty. Then CPU load slowly increase till Blender gets 100% of CPU.
After saving and restoring Blener takes 0.3% CPU again.
When I start playback by pressing play button in timeline window Blender didn't slows down.

I tried to compile and run Blender under Debian Linux on same box. Blender runs smooth.
But when I ran binary compiled in Debian under Gentoo bug appear again.

I think this bug appear only with Gentoo distribution. Can somebody help me fix it? I can debug Blender if yo give detailed instructions.

CPU: Athlon XP 2500+
MB: ABit KV7
OS: Gentoo Linux 2005.1 Optimazed
Kernel: 2.6.13-gentoo-r5

Blender compiled from official 2.41 sources

And one thing. Blender 2.3x works as well on my gentoo box.

I tried to switch video driver to vesa and opengl to xorg-x11. Same results.
Changing window mananger do nothing to.
Seems bug in library dependences.
Tommorow I'll try to update my system. Might be this helps

Maybe your make.conf have some weird flag.
Try dowloading the official build from b.org
If you builded your system with wrong flags, it can't be helped...

here is mine, I have a P4:
CFLAGS="-O2 -march=i686 -fomit-frame-pointer -pipe"
CHOST="i686-pc-linux-gnu"
CXXFLAGS="${CFLAGS}"

I tried blender-2.41-linux-glibc232-py24-i386-static. Same results.
But my system still not updated.

Problem solved by updating system and rebuilding all blender's dependences from empty tree.
Thanks for all! I am happy now!
