Hello OpenMPI developers,
I am searching for a way to discover _all_ configure options of an OpenMPI installation.
Background: in a existing installation, the ompi_info program helps to find out a lot of informations about the installation. So, "ompi_info -c" shows *some* configuration options like CFLAGS, FFLAGS et cetera. Compilation directories often does not survive for long time (or are not shipped at all, e.g. with SunMPI)
But what about --enable-mpi-threads or --enable-contrib-no-build=vt for example (and all other possible) flags of "configure", how can I see would these flags set or would not?
In other words: is it possible to get _all_ flags of configure from an "ready" installation in without having the compilation dirs (with configure logs) any more?
