gcc flag question

[DarkFuds]

What does the -o flag do with gcc?

Example:

gcc -o cpom file.c



Thanks

See if the following help:

Optimize. Optimizing compilation takes somewhat more time, and a lot more memory for a large function.
With -O, the compiler tries to reduce code size and execution time, without performing any optimizations that take a great deal of compilation time.

Uhm the -O is for Optimize, the -o is for output file... your example code is saying gcc write the compiled file.c out to cpom.

Next time check the man pages.
