Hi Roland, The toolkit is still building, but it looks like things are working properly and I want to thank you again for your help!
As you suggested, I added a .hostname file and ran ./simfactory/bin/sim build --clean --reconfig . I'm past the -fopenmp issue which plagued me for days! Thank you. While I was trying to get around the -fopenmp problem, I edited the file /Users/murray/Cactus/configs/sim/OptionList . I'm not sure if that file is input or output. It's input, but it might be both. I changed the version name (added a '_' at the end of the version string); set the compiler and preprocessor directives to use gcc-10, etc.; and turned the OpenMP options off. When I did the reconfig, the options I set were retained. And it looks like the toolkit is building properly! I'm going to see if I can build again while turning OpenMP back on, but I'll wait until this build is complete. It's taking a lot longer to build than I expected (my Macbook Pro is old -- early 2015), so I won't know until tomorrow. Again, thanks so much!
