Description
Git commit
Operating systems
Mac
GGML backends
BLAS
Problem description & steps to reproduce
The build fails with a number of errors, see the log extract below.
Reproduce: [Non-trivial due to hardware availability.] Run the build with MacPorts on powerpc-darwin.
First Bad Commit
I am not sure which commit introduced the breakage, but the last which was known to build fine is b52edd2 (bisecting is possible but will take forever)
