I compile an code in -m32 mode. My computer is intel 64bit cpu.

when i initial icc envirenment, should i source iccvar.sh ia32 or intel64 when i use icc to compile code with -m32 option?

you should source for intel64.

How about icx/icpx? I mean if I can build a C++ 32bit shared library with CMake and icx/icpx instead of icc?
