It is not a big deal, but i just find it hard to take it. Maybe its my problem :-/
The compiler's job is to produce assembly code given C source as input. The output of the compiler is fed to the assembler which translates all assembly code into machine code and finally the link editor sets up all the linkages to external functions.

Compiling the compiler is a process called bootstrapping similar to the way your machine boots up...more on it here.

C compiler to build Sparc/Solaris binaries on Linux

Just that the Subject says. I am looking for a C compiler for Linux x86 that will allow me to compile a C source code file and the resulting binary will be able to run on a Sparc running Solaris. Thanks. (2 Replies)
