dIt seems like this should be a simple problem. I am trying to get
OpenMPI
to compile on a CentOS 4.2 (like Redhat EL 4.2) box. It has
installed gcc
3.4, and gcc 4.0. I want to compile OMPI with gcc4, but I am
getting this
error. What am I doing wrong?
checking how to run the C preprocessor... gcc4
configure: error: C preprocessor "gcc4" fails sanity check
See `config.log' for more details.
[root@Cent01 openmpi-1.0.1]#
Could you include the config.log file -- it will have the information
we need to help you.
It looks like you have the environment variable CPP set to gcc4,
which is what is causing the problems. Without arguments, gcc4 runs
both the C preprocessor *and* the compiler. CPP should be set to
something that will run *only* the C preprocessor. I think you would
want to set CPP to either the C preprocessor installed with your gcc4
setup (I'll admit I dont' know what it is called when program
suffixes are added) or to something like "gcc4 -E".
Hope this helps,
Brian
