Hi all,
Before a complete re-installation of Julia in early December, MPI.jl worked for me. Now I cannot install the MPI.jl package anymore - it fails building:

```
The error message suggests to recompile with -fPIC. How can I make Julia do that?
Or do you believe the problem is elsewhere?
In any case, it should not be a big issue as MPI.jl worked before…
Thanks!

What version of CMake are you using? It looks like there was a [bug](https://gitlab.kitware.com/cmake/cmake/issues/17208) that was fixed in version 3.11. According to that thread, setting `CRAYPE_LINK_TYPE=dynamic` and adding `-fPIC` to `CMAKE_C_FLAGS` is a workaround. You may also need to add the flag to `CMAKE_Fortran_FLAGS` because there is a Fortran file in there too.

@JaredCrean2: The default CMake on the system, version 3.5.2, was used. I tried now also with the newest version available, version 3.8.1. Yet, it still fails. Note that I had always set CRAYPE\_LINK\_TYPE=dynamic (without that, it had failed much earlier in the build).
How do I properly modify the CMAKE flags that Julia is going to use for the build when calling `Pkg.build("MPI")`?

In the shell (before launching Julia), do
```julia
export CMAKE_C_FLAGS="-fPIC $CMAKE_C_FLAGS"
export CMAKE_Fortran_FLAGS="-fPIC $CMAKE_Fortran_FLAGS"
```
The open Julia and install MPI.jl as usual.

@JaredCrean2: I have tried that: the error is the same. Thus, it seems not to take these environment variables into account.
I have also tried with the following environment variables set (following [this section in the MPI.jl doc](https://github.com/JuliaParallel/MPI.jl#overriding-the-auto-detected-mpi-version)):
```julia
export JULIA_MPI_Fortran_COMPILE_FLAGS="-fPIC"
export JULIA_MPI_C_COMPILE_FLAGS="-fPIC"
```
The build failed with the same error.

Can you do
```julia
export VERBOSE=1
```
in addition to the other environment variables and post the output? That should show the exact commands the compiler is executing.

The `-fPIC` flag is definitely not getting to the compiler (both C and Fortran), which is weird because the CMakeLists.txt definitely uses `CMAKE_C_FLAGS`. Do you have GNU compilers available on your machine. If so, try doing `module swap PrgEvn-cray PrgEnv-gnu` (or similar depending on the module names). I want to see if this works with GNU compilers to see if this really is a bug with CMake and the Cray compilers.

Yes, if I swap to `PrgEnv-gnu`, then it works. See the following (done after a fresh login):

It must be a problem with CMake and the Cray compilers. You can try building a newer version of CMake yourself (something newer than 3.11) and see if that works with the Cray compilers.

Yes, absolutely.
As you could see above, building with `PrgEnv-gnu` worked; however the following still appeared in the configuring phase:
```julia
-- Looking for MPI_Comm_c2f
-- Looking for MPI_Comm_c2f - not found
```
Do you know the relevance of [MPI\_Comm\_c2f](https://www.mpi-forum.org/docs/mpi-2.0/mpi-20-html/node59.htm) for MPI.jl? What will not work (properly)?

The short answer is everthing will work fine.
The long answer is MPI.jl uses the Fortran MPI interface, but many MPI-aware libraries use the C interface. The MPI standard requires that either a C and Fortran communicator must be the same or the MPI library must provide functions to convert one to the other. The configure phase checks to see if the C to Fortran conversion function exists, and uses that information to define the proper conversion function wrappers in Julia.
