Reason is unclear so far.

I've taken ownership of libxc5/6, so you can assign to me directly. As for the issue, are you attempting to build with +tests?

And can you attach the full main.log so I can take a look?

[mascguy (Christopher Nielsen)]

p.s. It looks like it's the tests that are failing to build. And while the cmake-based build supports a formal option to disable building those, I'm not seeing a similar flag for the autotools-based build.

Still digging though...

Thank you! I will test that soon.

UPD. Yes, now it builds fine.

I am puzzled how this made it onto the link line:

/opt/local/lib/libxc.a

when that file should not exist during the build, and it should be linking in the one in the build tree, you would think.

I don't know for sure at the moment, but it would seem those missing symbols should be found in libxc.a.
