Compiling mpich

All the work having been done by configure, all we have to do now is

    make

This will clean all the directories of previous object files, compile both profiling and non-profiling versions of the source code, build all necessary libraries, and link both a sample Fortran program and a sample C program as a test that everything is working. If anything goes wrong, check Section  to see if there is anything said there about your problem. If not, send mail to mpi-bugs@mcs.anl.gov, including the output of the make. Therefore it might be a good idea to use

    make >& make.log &

Specific (non-default) targets can also be made. See the Makefile to see what they are.

After running this make, the size of the distribution will be about 20 Megabytes (depending on the particular machine it is being compiled for), before building any of the examples or the extensive test library. The Makefiles are built for the various example subdirectories, but the example programs themselfes have to be made ``by hand''.
