Dear OpenMPI folks,

I tried to buld the version 1.5.1 with different compilers, and the build with PGI compilers failed. I believe, the configuration of the final link stage goes not well - an option (LDFLAGS) explicitly given by configuring is partially lost. In the past we were able to build 1.4.x versions with the same compilers and configuration options, so it looks for me as a new configuration issue in 1.5.x


Configured with:

Note the use of "-tp k8-32" flag for building 32bit version. Similarly, for 64bit we use "-tp k8-64" flag with same behaviour. If compiling, the following error happens:

Looking to the underlying real command line which was called you will see the "k8-32" part of the LDFLAGS option being lost:
