kernel-source-2.4.7-0.11.1 fails to compile
Last modified: 2007-04-18 12:35:42 EDT
Trying to compile 0.11.1 with a custom config which enables MGA 400 DRI support for both X 4.0.3 and 4.1, I get: make[4]: Leaving directory `/build/linux-2.4.7-0.11.1/drivers/char/drm' make[3]: Leaving directory `/build/linux-2.4.7-0.11.1/drivers/char/drm' make -C drm41 make[3]: Entering directory `/build/linux-2.4.7-0.11.1/drivers/char/drm41' make all_targets make[4]: Entering directory `/build/linux-2.4.7-0.11.1/drivers/char/drm41' gcc -D__KERNEL__ -I/build/linux-2.4.7-0.11.1/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fomit-frame-pointer -fno-strict-aliasing -fno-common -Wno-unused -pipe -mpreferred-stack-boundary=2 -march=i686 -DEXPORT_SYMTAB -c mga_drv.c In file included from mga_drv.c:68: drm_bufs.h:391:2: warning: #warning DRM(realloc) can return NULL! drm_bufs.h:690:2: warning: #warning LEAK !! drm_bufs.h:716:2: warning: #warning DRM(realloc) can return NULL!

Ehm you can't have BOTH old and new DRM.... (yes I really really hate that part of DRM) But it seems there is another bug hiding as well; in -0.12.0 I changed DRM a lot (basically I upgraded it to a new version and changed directories to match Alan's and Linus' tree) and while I could spend time trying to fix -0.11.1 I'd much prefer to see/know if -0.12 is also broken and then fix THAT. Could you attach your .config ?
This defect is considered MUST-FIX for Fairfax.
Created attachment 27153 [details] kernel config for 2.4.7-0.11.1
Config attached, which works other than the dueling DRM issue. If you put 0.12 some place I can get to it, I'll try it instead ;-)
should be fixed now in 2.4.7-0.14.0
