Hello,
I am trying to write a config.ac script that will select between using a
regular C++ compiler or an MPI C++ compiler. I have something like:
if [ test "x$with_mpi" = "xno"];
then
AC_PROG_CXX
else
AX_PROG_CXX_MPI
fi
Later on I check for C++11 support, and then regular build succeeds but the
MPI build fails. However, if I change the order of the if statement above,
then the MPI build succeeds but the regular build fails (or using the mpi++
compiler even though it should not be set).
I am no bash scripting expert, but I am surprised the logic needs to be
more complicated than this? I also tried using AS_IF instead, with similar
results.
TIA for any helpful hints.
Matt
