error: conflicting types for 'MPI_User_function'
My name is Hannes Panzer and I am a research associate at the iwb of the Technical University of Munich.
In my research team, we are performing numerical simulations based on the finite element simulation tool CalculiX. Recently, we wanted to install the newest version (2.19) of the tool, along with PaStiX as the Solver, to increase the computational speed by performing calculations on the GPU. However, so far we were not able to install PaStiX without any error message, which is the following in our case:
error: conflicting types for 'MPI_User_function'
There are many similar error messages concerning MPI, even though the option MPI is turned off in the make file.
We wanted to ask you, if you have already encountered any error messages of this type when trying to compile PaStiX, and if you have an idea, what causes the problem and how it could be solved.
