Compiling a non-pic glibc

Compiling a non-pic glibc

[Alex Gonzalez]

Hi,

What is the correct way of cross-compiling a non-pic static glibc?

I thought something like,

env CC="mips64-linux-gnu-gcc -mabi=n32 -mno-abicalls -fno-pic -mips4"
../glibc-src/configure --host=mips64-linux-gnu
--build=i686-pc-linux-gnulibc2.2 --prefix=/usr
--with-headers=/mips64-linux-gnu/sys-root/usr/include/
--enable-add-ons=linuxthreads --without-cvs --with-fp --disable-shared

and 'make' will do it, but it fails with,

Just in case, I am trying to build glibc-2.3.1 with a gcc 3.3 based toolchain.

Thanks,
Alex

Forget it.  The non-PIC support for glibc is rotting away since ages.

Why do you want a non-PIC glibc?

You can't.  MIPS/Linux userspace toolchains only support PIC out of the
box; if you want to mess around with non-PIC toolchains expect to have
to hack glibc (and possibly other places).  In this case it looks like
GCC's CRT files are PIC.
