I have been unsuccessful building gcc 4.4.1 on a Sparc Enterprise T5120 running Solaris 10. Having not built any Solaris versions of gcc for many years, I'd appreciate any pointers this group might have. This Sun system comes with gcc version 4.0.4 (gccfss). Starting with gmp-4.3.1, I was able to successfully build and check the package with the preinstalled gcc. Similarly, mpfr-2.4.1 successfully built and checked with this compiler.
Producing new gmp and mpfr versions for GCC can happen in two ways : 1. one wants to do this one at a time, building, installing and testing these before doing the same with bare GCC 2. building all these at the same time during the GCC build You choosed the first way. When your target,'sparc-sun-solaris2.10', is a 'bi-arch' target, the 32-bit host/target being the default, you should build 32-bit versions of gmp and mpfr because the GCC binaries would be 32-bit as default.
On to gcc 4.4.1, I ran the configure with: ../configure CC='gcc -m64'
This causes the 32-bit default being overridden... Was the installed gcc-4.0.4 a 64-bit default one? Why it produced 64-bit versions for gmp and mpfr?
Without the 'gcc -m64' configure complained that GMP and MPFR weren't in place as the configure test attempted a 32 built compile.
Of course it did... If you would like to have a 64-bit GCC which produces 64-bit binaries as default and 32-bit binaries with '-m32', then I think your target should be 'sparc64-sun-solaris2.10' or 'sparcv9-sun-solaris2.10'. But then maybe the 'lib's must contain 64 stuff and 'lib/sparcv7's must contain 32-bit stuff... What does your '/usr/lib' have? Have you '/usr/lib' and '/usr/lib/sparcv9' or '/usr/lib' and '/usr/lib/sparcv7' ? Without any '--build=something --host=something --target=something' used in the GCC configure, the 'something's will be guessed... These guesses now told that you have a 32-bit opsys now, is that so? The most easy route could have been the way '2', to symlink the gmp and mpfr sources to the GCC sources, something like : [root@Dell gcc-4.4.1]# ls -l gmp mpfr lrwxrwxrwx 1 root root 12 2009-04-28 16:40 gmp -> ../gmp-4.2.4 lrwxrwxrwx 1 root root 13 2009-04-28 16:40 mpfr -> ../mpfr-2.4.0 Ie unpacking the gcc-4.4.1, gmp and mpfr sources into a common 'src' directory and then letting the gmp and mpfr sources being seen in the main gcc-4.4.1 src directory...
