Hello, I picked up gcc-4.6.1 and startet a build process on a sparc-solaris10 box with /opt/sfw and SolStudio 12.2 installed. I am using mpc-0.9, mpfr-3.0.1 and gmp-5.0.2 which I extracted in the gcc source directory and created a link as stated in the installation instruction/prerequisites. I also made sure the /usr/ucb is NOT in my path!
Here are my results: Trying to build using the installed gcc - ssol10% /opt/sfw/bin/gcc --version gcc (GCC) 3.4.2 Copyright (C) 2004 Free Software Foundation, Inc. This is free software; see the source for copying conditions.

Finally the build of the multilibs failed so I decided to give GNU as/ld from binutils a chance, so I configured with the following command: ../configure --prefix=/usr2/gnu --enable-languages=c,c++ CC=/usr/bin/cc --with-gnu-as --with-as=/usr2/gnu/bin/gas --with-gnu-ld --with-ld=/usr2/gnu/bin/gld Do not be irritated when this detects executables in $prefix/libexec/sparc=sun-solaris2.10/bin (as, ld, nm,...) - they have been installed there from binutils. Doing a make stops when building in lto-plugin: make[4]: Entering directory `/archive/sparc-solaris/gcc-4.6.1/ssol/lto-plugin' /bin/bash ./libtool --tag=CC --tag=disable-static --mode=compile /usr/bin/cc -DHAVE_CONFIG_H -I. -I../../lto-plugin -I../../lto-plugin/../include -DHAVE_CONFIG_H -Wall -Werror -g -c -o lto-plugin.lo ../../lto-plugin/lto-plugin.c libtool: compile: /usr/bin/cc -DHAVE_CONFIG_H -I. -I../../lto-plugin -I../../lto-plugin/../include -DHAVE_CONFIG_H -Wall -Werror -g -c ../../lto-plugin/lto-plugin.c -KPIC -DPIC -o .libs/lto-plugin.o cc: -W option with unknown program all To fix this, I edited lto-plugin/Makefile - yes this is generated.

Another restart of make yields a full build and I am able to install the compiler and use it. it seems to generate proper result (at least for C).
