Different versions of UNIX come with different compilers. cc normally invokes the default C compiler of the specific UNIX. This mostly means gcc, nowadays, but it doesn't have to. -- A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing on usenet and in e-mail?

On my Mandriva 2010.0 system, ... $ ll /usr/bin/cc lrwxrwxrwx 1 root root 3 2009-11-30 15:31 /usr/bin/cc -> gcc So cc is gcc.

From: OldSchool on 23 Feb 2010 11:58 linux installations <generally> have gcc installed. for other *nixes, the actual installed compiler varies. For example, on HP-UX, possibilities include cc, c89, aCC, gcc, and probably others, Base HP would have cc sym-linked to a compiler compatible w/ Kerninghan-Ritchie C to allow building kernals, c89 and aCC are optional / extra cost, while gcc might be installed separately.
