Hi,

When I try to use opam, it fails:

$ opam install menhir

#=== ERROR while compiling ocaml-system.4.07.1 ================================#
# context     2.0.1 | linux/x86_64 |  | https://opam.ocaml.org#34f81c06
# path        ~/.opam/default/.opam-switch/build/ocaml-system.4.07.1
# command     ~/.opam/opam-init/hooks/sandbox.sh build ocaml gen_ocaml_config.ml
# exit-code   1
# env-file    ~/.opam/log/ocaml-system-12254-60459a.env
# output-file ~/.opam/log/ocaml-system-12254-60459a.out
### output ###
# bwrap: execvp ocaml: No such file or directory

and if I do (in fish)
$ set -x OPAM_USER_PATH_RO /home/gabriel/.guix-profile/bin/

then I obtain the error:

$ opam install menhir

#=== ERROR while compiling ocaml-system.4.07.1 ================================#

# output-file ~/.opam/log/ocaml-system-13887-6cc03f.out
### output ###
# bwrap: Can't mkdir parents for /home/gabriel/.guix-profile/bin/: No such file or directory

Any idea on how to fix this?

Thanks,
Gabriel

That's thc limit of opam here, it always tries to install ocaml package with the ocaml compiler. Don't you have a compiler in your switch already though? If so, I wonder why it's not found. Could you try to modify your $PATH to add it?

Hi again,

After some experiments, and after looking at what did Nix, it seems that
wrapping opam does the trick (with a .opam-real and a opam).  I'll try
this and make a patch.

Cheers,
Gabriel

Hello,

Wrapping works except that the binary can't find libraries, how can I
add the libraries of the profile (e.g. =asm/socket.h= or =crti.o=) in
the wrapper?  The matter is to get the path of a profile (as if it was a
package in the ~inputs~ of the function).

Hi,

Digging some old bugs about OCaml, I hit #34620:

Well, I think it is another kind of bug than the reported one.

Closing?
