You should be able to run "./configure --help" and see a lengthy help message that includes all the command line options to configure.

Is that what you're looking for? 
No, he wants to know what configure options were used with some binaries.
Apparently even what configure options could have been used even if they weren't actually used.

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?

Many thanks
