Problem building gcc 4.3.3 on a YDL ppc64 machine

[David Saada]

Hello,
I have problems building gcc 4.3.3 on a YDL ppc64 (Mac) machine. Problems are probably related to the mpfr library.
I have installed latest gmp (4.2.4) and mpfr (2.4.1) libraries on the same machine, and configured gcc to use them as following:

./configure --prefix=/u/lni/gcc/4.3.3/powerpc-unknown-linux-gnu/ --with-mpfr=/u/lni/mpfr/2.4.1/powerpc-unknown-linux-gnu/ --with-gmp=/u/lni/gmp/4.2.4/powerpc-unknown-linux-gnu/

then ran make, and got the following:

Native gcc is 4.1.1, and binutils version is 2.16.91.
I've also tried adding lib directories under gmp and mpfr directories to the beginning of the LD_LIBRARY_PATH environment, but results were the same.

Any idea?
Cheers,
David.

Wouldn't the 64-bit libraries go in a /lib64/ directory?

Well, I've simply installed mpfr on a separate location (prior to installing gcc of course) with the --prefix=/u/lni/mpfr/2.4.1/powerpc-unknown-linux-gnu/ option. Did I miss anything?

It looks like, for example, you are trying to use 32-bit libraries in a
64-bit build.  mpfr originally didn't pay any attention to those issues of
keeping 32/64 things straight; if it hasn't improved for your target, it's
up to you to sort this out.
