MacPorts installs something called g++-mp-4.3?
Does the "mp" mean MacPorts, or is it something else? I can't find any documentation anywhere...
Thanks!
回答1:
It's GNU C++ as provided by MacPorts. The full form for GNU executables is <name>[-<variant>][-<version>]. The variant and version can be omitted to indicate that it is the primary executable with that name for the system.

Yes, 'mp' means MacPorts. g++-mp-4.3 is C++ compiler from GCC for MacPorts.
