[Dri-devel] Compiling drm modules

[<wi...@so...>]

This still refuses to work on my machine.
I am have kernel headers for 2.3.49 (most previous versions
have had problems too, I keep upgrading in the vain hope
there will be a fix).

If I try and compile the module with make -f Makefile.linux
I get loads of errors relating to undefined types etc. This is with
/usr/include/asm and /usr/include/linux symlinked in to /usr/src/linux/
include/asm-i386/ and /usr/src/linux/include/linux respectively.
Modifying the makefile so CFLAGS = -I/usr/src/linux/include fixes
these errors.
Unfortunately the compile still dies thus:

/usr/src/linux/include/asm/spinlock.h: At top level:
/usr/src/linux/include/asm/spinlock.h:26: conflicting types for `spinlock_t'
/usr/src/linux/include/linux/spinlock.h:50: previous declaration of `spinlock_t'/usr/src/linux/include/asm/spinlock.h:73: parse error before `void'
/usr/src/linux/include/asm/spinlock.h:88: parse error before `do'
/usr/src/linux/include/asm/spinlock.h:118: conflicting types for `rwlock_t'
/usr/src/linux/include/linux/spinlock.h:113: previous declaration of `rwlock_t'
/usr/src/linux/include/asm/spinlock.h:141: parse error before `void'
/usr/src/linux/include/asm/spinlock.h:150: parse error before `void'

Anyone else seeing this problem with the latest kernels?
I can't find any mention in the archives or on any other sites
out there. Surely this must be a simnple one to fix either in the kernel
or by fooling with the build system?
