Bug 39448 – compile for kernel 2.4.24 fails with NEW_DRM, FFB_DRM set in .config (structure redefinition in ffb_drv)

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Ferris McCormick (RETIRED) 2004-01-26 06:30:16 UTC]

If the .config for kernel 2.4.24 contains
=========
CONFIG_DRM_NEW=y
CONFIG_DRM_FFB=y
=========
(and you use the shortcut alias
alias sparc64make='make ARCH=sparc64 CROSS_COMPILE=sparc64-unknown-linux-gnu-')

Then the 'sparc64make oldconfig dep vmlinux'
gets
============
sparc64-linux-gcc -D__KERNEL__ -I/usr/src/linux-2.4.24-sparc/include -Wall 
-Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common

==============
and so on.


Reproducible: Always
Steps to Reproduce:
1.Have 'CONFIG_DRM_NEW=y' & 'CONFIG_DRM_FFB=y' in .config
2.[sparc64]make oldconfig dep vmlinix
3.

Actual Results:

But it happens on any system.  The one that matters is the one which actually
has a Creator on it.

Created attachment 24438 [details]
A config file which will generate the error

This config file will generate the error, although it is not the one used on
the system which has a Creator card on it.

There's already a patch for this one in sparc-dev-sources, or it's fixed upstream in later kernels if you prefer.

[Comment 3 Ciaran McCreesh 2004-01-26 07:11:05 UTC]

Uh, it's fixed in sparc-sources as well... Oops, not enough caffeine in me :(
