error installing LWT 4.0.1 on Ubuntu 18.04 with musl enabled ocaml compiler via opam #599
Description
I am using opam with compiler switch 4.06.1+musl+gcc+static+flambda on Ubuntu 18.04. (The compiler switch is based on the 4.06.1+musl+static+flambda compiler switch by replacing musl-clang with musl-gcc since musl-clang is not available for Ubuntu)
When installing lwt I get the following error:
$ opam install lwt
The following actions will be performed:
∗ install lwt 4.0.1
For the PPX, please install package lwt_ppx
For Lwt_log and Lwt_daemon, please install package lwt_log

Error: Rule failed to generate the following targets:
- src/unix/dlllwt_unix_stubs.soLooking further I see that there is a statically linked library liblwt_unix_stubs.a which probably should
have been used instead:
/.opam/4.06.1+musl+gcc+static+flambda/build/lwt.4.0.1$ find -name "*lwt_unix_stubs*"
./_build/default/src/unix/liblwt_unix_stubs.a
./_build/default/src/unix/lwt_unix_stubs.o
./_build/default/src/unix/lwt_unix_stubs.c
./src/unix/lwt_unix_stubs.c
Any, ideas? Thank you!
