I use Solaris 10, compiling with a custom g++ (3.4.6) and GNU binutils (2.17). Things have gone well on two different systems, but when I tried moving to a third, it all fell over. Basically, it is now using the CC linker, but I need to use options not available to it. I believe I have found the root of the problem, but I do not understand what could cause this, or how best to fix it.
From a system that works:
Code:
$ which g++ ; g++ -v ; g++ -print-search-dirs | grep '^program'
/usr/local/bin/g++

The contents of /usr/local/lib/gcc/sparc-sun-solaris2.10/3.4.6/specs are identical between the two, and all the packages and package details (pkginfo) appear to be identical. The critical difference is that, in the system that is not working, the program search dirs are `wrong'. Even though it is a copy of the same g++, it seems as though some `prefix' is different between the two environments: on the system that works, it checks /usr/local/libexec/gcc/sparc-sun-solaris2.10/3.4.6/, whereas the other checks /usr/sfw/sparc-sun-solaris2.10/../../libexec/gcc/sparc-sun-solaris2.10/3.4.6/.
What could cause this difference, and what is the best resolution to this issue?
EDIT: I forgot to mention, I have tried the -B option with g++, as well as GCC_EXEC_PREFIX and COMPILER_PATH, with no success.
