In fact compiling my f90 codes is quite fast as compared with the c++ code. The time-consuming step is liking them all with mpic++. My application is a mix of c++ and f90 parallel codes and the main program is written in c++. Therefore mpic++ is used as the last phase to compile main and create the application. This last liking phase is very slow and slows down debugging incredibly because I don't know about the unresolved symbols until I do this final linking. Thanks, -- Valmor

[OMPI users] very long linking time with mixed-language libraries
Hello, I am using mpic++ to create a program that combines c++ and f90 libraries. The libraries are created with mpic++ and mpif90. OpenMPI-1.2 was built using gcc-4.1.1. (below follows the output of ompi_info. The final linking stage takes quite a long time compared to the creation of the libraries; I am wondering why and whether there is a way to speed up.
