Neil, config.log is in the directory in which you ran configure. Please also compress and post the output of make Cheers, Gilles On 5/31/2018 10:03 AM, Neil k8it wrote: ok here is a progress report. first I want to thank you both for getting me this far. gilles I think you were right about setting the CFLAGS and LDFLAGS =-march=armv6 it got to the first make command and after about an hour going good, It crashed when it started make 3.

Unfortunately, this is not enough information -- we need to see the exact error messages, precise descriptions of the environment in which you are running, what types of runs work and what types of runs fail, ...etc. Saying "it doesn't work" simply isn't enough to provide even a guess as to what is wrong in your environment.

Re: [OMPI users] need help finding mpi for Raspberry pi Raspian Streach
Forgive me for chipping in here. There is definitely a momentum behind the ARM architecture in HPC. However it seems to me that there are a lot of architectures under the 'ARM' umbrella. Does anyone have a simplified guide to what they all mean?
