Can you be more precise about the Sun issue? I found the mpir version in Sage would not build on Solaris x86, but would on Solaris SPARC. Here are a few facts, which you might find helpful if you are not familiar with Suns and Solaris. 0) Sun build machines based on both their own SPARC and Intel/AMD x86 processors. SPARC and x86 processors are totally incompatible at the assembly code level, so if you write assembly code, you need to write different versions. However, well written 'user-land' code writen in a high-level language should only need to be recompiled to run on x86 or SPARC hardware. 1) Sun provide a linker /opt/ccs/bin/ld which is installed with a full Solaris install. 2) Sun provide an assember /usr/ccs/bin/as which is installed with a full install of Solaris. 3) /opt/SUNWspro/bin/cc is a C compiler, not a C++ compiler. 4) /opt/SUNWspro/bin/CC is a C++ compiler. 5) Neither /opt/SUNWspro/bin/cc (C compiler) or /opt/SUNWspro/bin/CC (C++ compiler) are installed by default. You have to install them. Downloading SunStudio (free) is the way to do that. 6) Recent versions of Solaris provide /usr/sfw/bin/gcc (C compiler) and /usr/sfw/bin/g++ (C++ compiler). These are installed by default. 7) gcc on Solaris can be configured to use either the Sun or GNU linker and assembler. Different people configure GCC different ways, so you should not assume anything about the linker or assembler unless you test to see what gcc/g++ is using. 8) Sun do provide a GNU versions of a linker, as /usr/sfw/bin/gld Note the 'g' in front of the normal name for a linker. 9) Sun provide a GNU version of an assembler as /usr/sfw/bin/gas - again note the 'g' 10) In Solaris 10 update 7 (as used on 't2'), both /usr/sfw/bin/gcc and /usr/sfw/.bin/g++ use the Sun linker and assembler and ignore the GNU ones. But in general, you should not make assumptions about the linker or assembler. 11) Whilst the GNU and Sun compilers, assemblers and linkers share some options (compilers use -g for debugging), 95% of the options that can be used on the GNU tools can not be used on the Sun tools, and visa versa.
