Well, that is why build systems call the compilation twice or more, depending on which configurations they want to compile. >If you're building for a different setup than the one >you're compiling on, it's essentially a trivial case of >cross-compiling, and as usual for a cross-compile, you need to specify >the right compiler. > Or in the case of libhugetlbfs the right two >compilers, one for the 32-bit target arch and one for the 64-bit >target arch. Well, what if the target to compile for only has one type of bitness you don't know in advance (but xgcc produces the "right" thing)? What if that bitness is neither 32 nor 64? 1. CC32="xgcc" CC64="" 2. CC32="" CC64="xgcc" 3. something else ------------------------------------------------------------------------------ SOLARIS 10 is the OS for Data Centers - provides features such as DTrace, Predictive Self Healing and Award Winning ZFS.
