Re: Question about include path
Thank you,
to fix my problem, I just added
#ifndef _LIBC_LIMITS_H_
#include "/LFS2011/include/limits.h"
#endif
on top of /LFS2011/lib/gcc/i586-pc-linux/4.5.2/include-fixed/limits.h
I tried to understand why (GCC) limits.h is into include-fixed, without
success.
I found Ian message here :
http://gcc.gnu.org/ml/gcc/2007-12/msg00095.html but my glibc is not
buildt with "-nostdinc" option.
