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
- Show the commands that would be used without
- 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.
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.
