py-numba reports meaningless error: Unable to execute port py311-numba: invalid command name "registry::open" (can be closed as invalid)

Perhaps the problem is that it depends on py-llvmlite, which in turns pulls in dependency on Clang, which obviously will not build on PowerPC. But perhaps some coherent message could be emitted. Setting supported_archs to archs actually supported should resolve the issue.

If you provided a log or debug output it might be possible to see where that message is actually coming from and do something about it.

Replying to jmroot:

Thank you for pointing out, log was helpful. Turns out that it relies on libcxx port to decide whether this is buildable. While this is perhaps wrong in principle, it works as of now, since libcxx port is Intel-only. So I would get this normally:

Error: Cannot install llvm-14 for the arch 'ppc' because

is a bug.
Error: Processing of port py310-numba failed

However I had libcxx for ppc locally (it trivially builds with no hacks in fact, just minor fixes for the build system), and that did not work for detection:

Removing a local libcxx (which in fact should be removed, since we got libcxx-powerpc which is separate and newer version), I am back to the sensible error message.

So my initial report is a result of confusion. Sorry for that.

Yet, perhaps, it is llvm should fail as being for arm64 i386 x86_64 (it is genuinely unsupported on PowerPC, at least as of now, and will not build), and not libcxx, which a) builds fine and b) can be used with gcc, so it is not something meaningless to have built.

OK, so this was just due to you trying to use registry::open in a Portfile.
