[pmetzger (Perry E. Metzger)]

It works for me on Sonoma. I find this puzzling.

[pmetzger (Perry E. Metzger)]

(BTW, I have no PowerPC hardware nor has any been made by apple in a very long time. You can feel free to debug that if you like.)

Replying to pmetzger:

I solved the first error (it is the same as with Dune, so borrowing a fix from there works), but the got __Unwind_Resume undefined symbols. That often happens when C compiler is used to link a library instead of C++ one. However, I could not easily find where it is even set in Makefiles. Do you have an idea?

16. S. For Sonoma, I will clean everything and try again. But I installed everything default there. Puzzling.

Same result, still fails. I have nothing custom Ocaml-related on this system, and pretty much everything is default (well, I have upgraded MPICH to use modern Fortran, but I am sure it is irrelevant for opam). So no ideas too.

[barracuda156]

Still fails on 14.2 with Xcode 15.1

[pmetzger (Perry E. Metzger)]

It is now failing for me. I can't explain why. The "sed" invocation in the Makefile doesn't even look like it could work in principle given that the file it's trying to access isn't in the directory where the build is happening. This is all quite puzzling. I don't know if I have time to work on it very soon, so please feel free to go after the problem.

Should we bring this to upstream?

[pmetzger (Perry E. Metzger)]

Yes, but try building it straight without MacPorts first just to exclude the possibility that it's our fault.

UPD for PowerPC (just to keep track): I got to the following:

And I think I know how to fix this now. Hopefully.
