Dear Christof,


That sounds it might be the root of the problem! Thanks!


I’ve tried to use the Cygwin package manager where possible, but this means some of the packages may not have the correct options set. It seems very likely that this is the cause. I’ll uninstall hdf5 and the reinstall it from the recipe on the OPAL wiki, see if that sorts me out.


Thanks to suggestions from others as well. I wasn’t aware of the Windows Subsystem for Linux until now—if I didn’t already have lots of stuff set up in Cygwin, I think that would be the best way forward for me. I’ll try again in Cygwin, and if all fails, try to install Linux via the WSL.


Thanks for the help!

Hi Matt,


do you use the hdf library that comes with cygwin? I could be wrong but I think the problem is that cygwin hdf5 library wasn't compiled with support for parallel execution. I'll try to compile it myself.

Hello there!

I’m trying to set up OPAL for the first time. Sadly my work computer runs Windows, which makes things more difficult. Has anyone had success using OPAL on Cygwin before?

I’m currently stuck on the step of installing H5hut. I think I’ve got all the prerequisites installed properly. The configuration seems to go ok. But in the build step I get an error: “Unknown type name ‘MPI_COMM’”.

If I add “include <mpi.h>” to h5_types.h, then this error goes away, but I think this should a be a configuration issue, I don’t think I should be messing with the source code. Even with this include line added, I get a later error that various “HSPset_xxxx_mpio” functions are not defined properly. It seems to be that the connection from H5hut to Open MPI isn’t working properly…

Thanks so much for any help!
