Hi

while compiling magma 1.7 or 2.0 on arm64 platform i m facing this error

how can i handle this situation. is arm64 a supported platform ? is this a gcc bug ?

thanks for your advice

It appears that the issue is in compiling the sparse routines. Do you need sparse linear algebra, or just dense linear algebra routines? Can you compile just the dense routines (skipping the sparse linear algebra)? Using:

make lib
make test

That should create lib/libmagma.a, lib/libmagma.so (if you have FPIC set), and testing/testing_* testers.

To try compiling the sparse routines:

make sparse-lib
make sparse-test

Also, can you post your make.inc file, which shows us how you are setup.

We have not done extensive testing on ARM platforms.
