How can I compile/run C or C++ in Unix console or a Mac terminal?
(I know it, forget it, and relearn it again. Time to write it down.)
If it is a simple single source program:
where the source file is foo.c or foo.cpp, etc.
You dont even need a makefile. Make has enough built-in rules to build your source file into an executable of the same name, minus extension.
Running the executable just built is the same as running any program - but you will most often need to specify the path to the executable as the shell will only search what is in
$PATH to find executables, and most often that does not include the current directory (
So to run the built executable
gcc main.cpp -o main.out ./main.out
