[Clfs-support] [Native Compiler] Problem Cross-compiling GMP MPFR and MPC

[Michele Bucca]

Hello Everyone,

I'm trying to cross-compile a native host-x-host compiler with the
musl-libc library

To do that I have to

1) compile a cross-compiler. (Done)
2) Install GMP, MPFR and MPC on the cross-compiler
3) make a host-x-host cross-compile to make a native compiler

Now I'm stuck compiling the GMP, MPFR and MPC...

I had problems with MPFR because when I tried to compile them with the
following configure switches

../mpfr-3.1.4/configure --host=i486-linux-musl
--prefix=/home/michele/tmp/musl-native-toolchain/native/i486-linux-musl/

it produced me x86_64 libraries! (My host is x86_64-linux-gnu)

So I changed the configure switch like that:

../mpfr-3.1.4/configure --host=i486-linux-musl
--build=x86_64-linux-gnu
--prefix=/home/michele/tmp/musl-native-toolchain/native/i486-linux-musl/

and it compiled well..

Now I'm having problems building MPC for the same reason: the
configure is like this:

../mpc-1.0.3/configure --host=i486-linux-musl
--build=x86_64-linux-gnu
--prefix=/home/michele/tmp/musl-native-toolchain/native/i486-linux-musl/

what am I doing wrong?
