# mpicc > Open MPI C wrapper compiler. > The wrappers are simply thin shells on top of a C compiler, they add the relevant compiler and linker flags to the command-line that are necessary to compile/link Open MPI programs, and then invoke the underlying C compiler to actually perform the command. > More information: . - Compile a source code file into an object file: `mpicc -c {{path/to/file.c}}` - Link an object file and make an executable: `mpicc -o {{executable}} {{path/to/object_file.o}}` - Compile and link source code in a single command: `mpicc -o {{executable}} {{path/to/file.c}}`
