Re: CUDF and race conditions

[Julien Lepiller]

If ocamlbuild is at a version that doesn't have the fix yet, how about applying the first two patches of this MR?  https://github.com/ocaml/ocamlbuild/pull/302/commits

Thanks for your work on this!

Hey all,

I am currently working on a new branch wip-ocaml to try and get our
ocaml packages to build against latest 4.11

For some reason, when building ocamlbuild against 4.11 there is a race
condition which is introduced where cudf fails to build. I can not seem
to decipher how to resolve the issue, though.

--8<---------------cut here---------------start------------->8---
Failure:
  Error during command "mkdir /tmp/guix-build-ocaml-cudf-0.9.drv-0/cudf-0.9/_build": Ocamlbuild_pack.My_std.Exit_with_code(10).
make: *** [Makefile:61: _build/cudf.cma] Error 2
--8<---------------cut here---------------end--------------->8---

I did manage to find this relevant issue though:
https://github.com/ocaml/ocamlbuild/issues/300.

Any help would be appreciated.
