Bug 348419 – x11-libs/libdrm-2.4.23[video_cards_nouveau] breaks <=x11-drivers/xf86-video-nouveau-0.0.16_pre20101010

• Product: Gentoo Linux
• Status: RESOLVED WORKSFORME

[Description Charles Nérot 2010-12-11 12:54:50 UTC]

x11-libs/libdrm-2.4.23[video_cards_nouveau] breaks <=x11-drivers/xf86-video-nouveau-0.0.16_pre20101010.

Because it deploys a /usr/include/nouveau/nouveau_channel.h that is not compatible with <=x11-drivers/xf86-video-nouveau-0.0.16_pre20101010



Reproducible: Always

Steps to Reproduce:
1.emerge =x11-libs/libdrm-2.4.23
2.emerge =x11-drivers/xf86-video-nouveau-0.0.16_pre20101010
3.

Actual Results:  
compilation fail
=> X does not launch any more

Expected Results:  
emerge ok 

works fine with =x11-libs/libdrm-2.4.22

plus: mesa doesn't compile either

using a mesa lib compiled against libdrm 2.4.22 makes X crash

Worksforme with xf86-video-nouveau-0.0.16_pre20101130

The mesa issue (which should have been reported in a different bug) is presently being looked into.
