Hello all,
I am trying to create a toolchain by hand and I am facing some problems when
I try to configure the glibc 2.7 for a powerpc. When I try to configure the
glibc to install the headers I get the following error:
configure --prefix=/usr --host=powerpc-440-linux-gnu
--with-headers=${SYSROOT}/usr/include --disable-shared --without-cvs

I already have the binutils 2.18 compiled on my PATH. I know that it is
easier to use a script like crosstool to compile it but I do want to
understand what is happening behind the scenes.
Regards.
Ademir
