Compiles and links MPI programs written in C++


This command can be used to compile and link MPI programs written in C++. It provides the options and any special libraries that are needed to compile and link MPI programs.

It is important to use this command (or a Makefile processed with mpireconfig) particularly when linking programs, as it provides the necessary libraries. It can also simplify the use of the MPE profiling libraries, through the use of the -mpilog, -mpitrace, and -mpianim commands.

mpiCC cannot be used to compile C programs. Use mpicc for C programs.

Command line arguments

Build version that generate MPE log files
Build version that generates traces
Build version that generates real-time animation
Show the commands that would be used without runnning them
Give short help
Show exactly what this program is doing. This option should normally not be used.
are passed to the compiler or linker. For example, -c causes files to be compiled, -g selects compilation with debugging on most systems, and -o name causes linking with the output executable given the name name.

Environment Variables

The environment variables MPICH_CCC and MPICH_CCLINKER may be used to select different C++ compiler and linker. Note that since MPICH is built with a particular C++ and C compiler, change the compilers used can cause problems. Use this only if you could intermix code compiled with the different compilers.


To compile a single file foo.c, use
   mpicc -c foo.c 

To link the output and make an executable, use

   mpicc -o foo foo.o
Combining compilation and linking in a single command
   mpicc -o foo foo.c
is a convenient way to build simple programs.
