6 years ago I can't reproduce that (but I'm on opam v2.). Isn't that a case of missing eval $(opam config env) (though in practice I think it should not be needed for installs to work).

6 years ago @djs55 can you reproduce without starting from an opam init ? If that is the case a clear command sequence that leads to the issue would be nice to have. Thanks.

6 years ago Here's a full trace (still from opam init) after I deleted my ~/.opam and started a fresh shell:
Davids-MBP-2:~ djs$ set | grep opam
Davids-MBP-2:~ djs$ opam init

Done.
In normal operation, OPAM only alters files within ~/.opam.
During this initialisation, you can allow OPAM to add information to two
other files for best results. You can also make these additions manually
if you wish.
If you agree, OPAM will modify:
- ~/.profile (or a file you specify) to set the right environment
variables and to load the auto-completion scripts for your shell (bash)
on startup. Specifically, it checks for and appends the following line:
. /Users/djs/.opam/opam-init/init.sh > /dev/null 2> /dev/null || true
- ~/.ocamlinit to ensure that non-system installations of `ocamlfind`
(i.e. those installed by OPAM) will work correctly when running the
OCaml toplevel. It does this by adding $OCAML_TOPLEVEL_PATH to the list
of include directories.
If you choose to not configure your system now, you can either configure
OPAM manually (instructions will be displayed) or launch the automatic setup
later by running:
opam config setup -a
Do you want OPAM to modify ~/.profile and ~/.ocamlinit?
(default is 'no', use 'f' to name a file other than ~/.profile)

Global configuration:
Updating ~/.opam/opam-init/init.sh

1. To configure OPAM in the current shell session, you need to run:
eval `opam config env`
2. To correctly configure OPAM for subsequent use, add the following
line to your profile file (for instance ~/.profile):
. /Users/djs/.opam/opam-init/init.sh > /dev/null 2> /dev/null || true
3. To avoid issues related to non-system installations of `ocamlfind`
add the following lines to ~/.ocamlinit (create it if necessary):
let () =
try Topdirs.dir_directory (Sys.getenv "OCAML_TOPLEVEL_PATH")
with Not_found -> ()

The configure of ocamlfind says:
- num: foundwhich is odd as 4.06 doesn't include num.cmi any more. Perhaps it's picking up a stale file somewhere?

6 years ago OK I think I know what's going on. opam install num (when it works):
- install -m 644 nums.cma libnums.a big_int.cmi nat.cmi num.cmi ratio.cmi arith_status.cmi big_int.mli nat.mli num.mli ratio.mli arith_status.mli big_int.cmti nat.cmti num.cmti ratio.cmti arith_status.cmti nums.cmxa nums.a big_int.cmx nat.cmx num.cmx ratio.cmx arith_status.cmx nums.cmxs /usr/local/lib/ocaml
- install dllnums.so /usr/local/lib/ocaml/stublibsthis is because it writes directly into the stdlib directory, not the opam switch: https://github.com/ocaml/num/blob/master/src/Makefile#L9
and then if I blow away my .opam and start again, these files persist, which cause ocamlfind to install a META file (because the library looks like it came with the compiler) and which causes the second opam install num to fail. The uninstall of num cleans up the files added on the first invocation.

6 years ago OK I'm pretty sure I at least know what's going on. I've made a proposed fix in the linked PR... although I'm not sure it's actually worth it (possible backwards compatibility issue versus irritating occasional glitch)

6 years ago @djs55 it seems upstream has a fix (@gerdstolpmann see https://github.com/ocaml/opam-repository/issues/10925#issuecomment-350302281) could you please try to test it so that we can move on this.

4 years ago I'm having the same issue now (on Ubuntu 19.10). It might be due to having a relatively old .opam directory.

4 years ago I am likewise getting this issue (MacOS)
[ERROR] It appears that the num library was previously installed to your system compiler's lib directory, probably by a faulty opam package. You will need to remove arith_flags., arith_status., big_int., int_misc., nat., num., ratio., nums., libnums. and stublibs/dllnums. from /usr/local/lib/ocaml.
However none of those files are present in /usr/local/lib/ocaml.
I solved it by executing ocamlfind remove num and then ocamlfind remove num-top followed by opam install num.

There seems to be a problem with the "built-in" num library, but I'm not sure whether the problem is the metadata in this repo or somewhere else.
On a Mac with OCaml 4.06 from homebrew (
brew install ocaml):but then if I
I think as a clean up it executes
ocamlfind remove numsomewhere because now:
