If I remove the above entries, and if I have only this entry now in my
libclone.h
#ifndef SYS_unshare
#ifdef __NR_unshare
#define SYS_unshare __NR_unshare
#elif __i386__
#define SYS_unshare 310
#elif __ia64__
#define SYS_unshare 1296
#elif __x86_64__
#define SYS_unshare 272
#elif __s390x__ || __s390__
#define SYS_unshare 303
#elif __powerpc__
#define SYS_unshare 282
#else
#error "unshare not supported on this architecure."
#endif
#endif
I am getting this
e326m:~/tmp/ltp-full-20080731/testcases/kernel/containers/libclone # make
cc -c -o libclone.o libclone.c
In file included from libclone.c:17:
libclone.h: In function ‘unshare’:
libclone.h:83: error: ‘__NR_unshare’ undeclared (first use in this function)
libclone.h:83: error: (Each undeclared identifier is reported only once
libclone.h:83: error: for each function it appears in.)
make: *** [libclone.o] Error 1
So the variables SYS_unshare or the __NR_unshare is not defined.
I tried this on the tree ( 2.6.27-rc2 kernel)
git://git.kernel.org/pub/scm/linux/kernel/git/daveh/linux-2.6-lxc.git
How do I proceed ?
