Re: gcc + uclibc

[Alberich de megres <alberich2k5@xxxxxxxxx>]

After some testings, and check your script and link (thanks for both),
i'm having a different problem:

while building gcc step 2, and libgcc:
libgcc/../gcc/libgcc2.c:29:
/opt/x/usr/include/pthread.h:25:19: fatal error: sched.h: No such file
or directory

In pthread.h I can see the include line is this one:
#include <sched.h>

while headers are located at include/linux/sched.h

shouldn't it be:
#include <linux/sched.h>

thanks!
