Thread: How to compile C program in Linux?

C++: g++ -o executable source.cc
C: gcc -o executable source.c

If you don't specify the object file with -o, it defaults to a.out.

For more information on all of the different options: man gcc

The object file is the program. If you just say g++ source.cpp, it will compile the code and make a.out the executable. On the other hand, if you specify one, it will compile and make it.

g++ -o exec source.cpp, will result in making a file called "exec" as the compiled version of source.cpp.

As for the file issue, I believe http://faq.cprogramming.com/cgi-bin/...&id=1043284392 should help.
