Good evening,

I tried to build a project with dune, and it failed while trying to
access '/usr/lib/ocaml/METAS':

$ dune build lambdapi.exe

Entering directory '/data0/gabriel/workspace/vcs/lambdapi'
Error: exception Sys_error("/usr/lib/ocaml/METAS: No such file or directory")

I must not segfault.  Uncertainty is the mind-killer.  Exceptions are
the little-death that brings total obliteration.  I will fully express
my cases.  Execution will pass over me and through me.  And when it
has gone past, I will unwind the stack along its path.  Where the
cases are handled there will be nothing.  Only I will remain.

I'll probably have a look at it tomorrow.  If someone has an idea
though, let me know.

Cheers,
Gabriel

Is /usr/lib/ocaml/METAS referenced somewhere in the sources you're
trying to build?

Maybe you could try setting these environment variables:
OCAMLFIND_DESTDIR=<somewhere>
and
OCAMLFIND_LDCONF=ignore

that's what we do in the dune-build-system.

Checking this is indeed a good idea, but no, the path isn't referenced
in the sources.

The DESTDIR is used when installing files, isn't it?  Here it seems to
be rather a problem of source directory though.

The error was mine, sorry, ocamlfind was not installed through guix and
thus the paths returned were wrong.  I'm closing this.
