I get the same message if I run make again. But the error might be nondeterministic; on the previous clean build the missing symbol was dlerror.

I see that neither -lm nor -ldl is present in the command line above.

Closing as a dupe of #10743 which will be fixed by #10777

I think that all this breakage is just linker differences among systems and I just got lucky in that the linkers on the bots accepted this and other systems apparently aren't.

I still get this with a clean build on ad58e2c, which includes #10777

Can you re-paste the error message? (reopening in the meantime)

Ah, this is just a bootstrapping process. We just need a snapshot to land (the error is at stage0 where the old behavior is still in effect).

I'm in the process of making a new snapshot and will hopefully have that up shortly.
