Problem installing

[johnbamberg]

Hi everyone,

When I'm installing the most recent version of gap (15.1), I get segmentation faults when make gets to the stage of using test-driver. Here is part of the output:

It gets stuck on the last one, and I have to CTRL+C. I'm using a 2020 MacBook (so Intel) and OS 15.7.3.

Those error messages are coming from 'libgmp'. The best solution would be to install libgmp from somewhere else (do you use any package managers, like brew?), and then if you reconfigure GAP it should use the system installed version which may be more up to date.

Resolved. I upgraded the gcc using brew install gcc and now everything is fine. This is a common problem on Mac's when relying upon Xcode.

I would still recommend doing brew install gmp readline to install GMP and GNU readline, then recompile GAP (i.e. run ./configure && make again for an optimal experience.
