mpiCC(1) MPI Commands mpiCC(1)NAMEmpiCC - Compiles and links MPI programs written in C++
DESCRIPTION
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-mpilog
- Build version that generate MPE log files
-mpitrace
- Build version that generates traces
-mpianim
- Build version that generates real-time animation
-show - Show the commands that would be used without runnning them
-help - Give short help
-echo - Show exactly what this program is doing. This option should
normally not be used.
others - 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 exe‐
cutable 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.
EXAMPLES
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.
