gcc + uclibc

[Alberich de megres]

Thanks for the replies.

I am using --with-sysroot=/opt/x, on both gcc stage 1 and final.
you can check the configurations in my first email.

But my problem is that uclibc files are at:
/opt/x/usr/arm-linux-uclibc/usr/include/stdio.h

Do I need to change for gcc final stage the sysroot to:
--with-sysroot=/opt/x/usr/arm-linux-uclibc/

thanks!
