[Xenomai-help] mutex_init() error when build

Hi,

I am using Xenomai-2.1.0 on Blackfin uClinux. When enabling "POSIX"
interface and build the kernel, I got error message:

"make
make ARCH=blackfin CROSS_COMPILE=bfin-uclinux- -C linux-2.6.x  || exit 1
make[1]: Entering directory
`/home/adam/workspace/kernel/adeos/uClinux-dist_0425/linux-2.6.x'

make[2]: *** [kernel/xenomai] Error 2
make[1]: *** [kernel] Error 2
"

include/linux/mutex.h:

extern void fastcall __mutex_init(struct mutex *lock, const char *name);

The function definition is different. I tried to add "static" in syscall.c:
__mutex_init(), still cannot work. Could you please help?

Thanks,
-Yi

It's a known issue involving a naming conflict between 2.6.16 and Xeno 
2.1.x. This has been fixed in 2.2, but we will likely have to backport 
this fix.

This has already been fixed in 2.1.1. Please upgrade.

The fix was backported, commit 772, and is included in release v2.1.1:
