make[1]: *** [Makefile:1513: gpt_gpu.gcn_hsa.bc] Error 1

I tried passing compiler flags to ./configure, such as CCFLAGS="--opaque-pointers", but that doesn't work (and doesn't seem like the right solution).

Any help would be appreciated!

You should be able to pass --disable-opencl to ./configure for the time being until I can assess this further.

Thank you very much for getting back to me so quickly! That did the trick - my build completed successfully

I ran into something else, but unrelated, so will open a separate issue
