3.0 regression: I/O error: *stubs.so: no such file or directory #5282
Description
Hi!
I just tested the latest version of dune (6a0314c) on js-monorepo.
I'm seeing build errors that happen on this dev version but not on 2.9.1.
More precisely here's the output of a second dune build (the first one contains extra warnings that are not relevant):
$ dune build
File "_none_", line 1:
Error: I/O error: dllnum_stubs.so: No such file or directory
File "_none_", line 1:
Error: I/O error: dllpcre_stubs.so: No such file or directory
File "_none_", line 1:
Error: I/O error: dllreplace_caml_modify_for_testing_stubs.so: No such file or directory
File "_none_", line 1:
Error: I/O error: dllzarith_c_stubs.so: No such file or directory
File "_none_", line 1:
Error: I/O error: dlllwt_unix_stubs.so: No such file or directory
Reproduction
git clone https://github.com/emillon/js-monorepo
cd js-monorepo
opam monorepo pull
dune build
With 2.9.1 this succeeds, but with the dev version it fails.
