Open terminal
$ brew install ocaml
$ brew install opam
$ sudo opam init
$ sudo opam install topkg (without sudo doesn't work as well)

Hello, do not use sudo with opam it's not needed.

Could you try to do eval $(opam config env) before trying to install. Since you are on 4.05.0 I suspect you are running in this bug.

dbuenzli commented 6 years ago

I'm closing this since I don't think it's a problem with topkg. But feel free to continue the discussion here if what I mentioned above didn't solve your problem.

vol24pl commented 6 years ago

writing eval 'opam config env' helped

dbuenzli commented 6 years ago

Thanks for getting back with the answer !

philCryoport commented 2 years ago

I am having the same issue:

MacOS Monterey
Have already
- brew install opam
- opam init
- opam config env
- ...and have installed other packages (trying to get csvtool installed)

Two issues appear to be happening:

# no C toolchain detected, using ""
# ocamlfind: Package 'threads' not found

Help?

dbuenzli commented 2 years ago

Ok so you are using a system switch (i.e. an opam switch that uses the system install of ocaml).

Unfortunately there's all sort of things that can go wrong with system switches. But nothing obvious I can see right here from your outputs. The problem seems to be due to ocamlfind, just confirm that:

opam exec -- command -v ocamlfind

returns the opam installed ocamlfind and not one installed elsewhere.

But rather I first suggest you to do a regular switch and see if the problem remains (my bet is that it won't).

opam switch create 4.13.1 
eval $(opam env) 
opam install csvtool

Now running the second batch of commands. It's currently compiling. I'll update here when that's done.

Out of curiosity, should I brew uninstall ocaml?

No, I bet that will uninstall opam from brew. It's just better to use opam non-system switches afterwards.

When it errors it mentions these two files:

There's definitively something wrong with ocamlfind.

Btw. could you just make sure you have the lastest opam repository do an opam udpate and try again.

OCaml host-os conf: cmd ['ocamlfind' 'ocamlc' '-config']

Ah yes that's the rune so what's the output of

opam exec -- ocamlfind ocamlc -config

(it exits abnormally with 2 let's see what it says)

dbuenzli commented 2 years ago

Oh and the output of

opam exec -- ocamlfind printconf

please.

Now run 'opam upgrade' to apply any package updates.

➜ opam upgrade
Everything as up-to-date as possible (run with --verbose to show unavailable upgrades).

The following packages are not being upgraded because the new versions conflict with other installed packages:
  - ocaml.5.0.0
    ∗ dune.3.0.3 is installed and requires ocaml < 4.08~~
However, you may "opam upgrade" these packages explicitly, which will ask permission to downgrade or uninstall the conflicting packages.
Nothing to do.

@kit-ty-kate and @dbuenzli in case it's any easier, I've sent both of you a Teams meeting invite so we can do this more interactively

kit-ty-kate commented 2 years ago

I have a hunch. Could you clone https://github.com/ocaml/ocamlfind/ and run ./configure and see if any error messages occures?

Not sure if that could be a problem but does the <user> path segment you are eliding contain spaces or other characters beyond US-ASCII printable characters ?

philCryoport commented 2 years ago

Nope. It's normal "a" to "z" characters, no spaces, no special characters

Sorry I can't make it now. Tell me what you find out or if I can be of any further help.

kit-ty-kate commented 2 years ago

@philCryoport my connexion is too flaky to continue (+ it’s getting late here) but i guess we found some kind of origin of the problem and it needs some more debugging

philCryoport commented 2 years ago

Hi @kit-ty-kate I'm going to file an issue with ocamlfind as the code is a bit too "ninja" and it's breaking things.

The original line from the ocamlfind Makefile:

    for x in `ls site-lib-src`; do test ! -f "site-lib-src/$$x/META" || echo $$x >> Makefile.packages.in; done

The intended idea is:

Iterate over a list of site-lib-src directories & files; call the current iterated value x
If site-lib-src/x/META is a regular file, return exit code 1; else return exit code 0
If the exit code is non-zero -- meaning that it was a regular file -- then echo that x into the Makefile.packages.in -- else go to next entry in the ls site-lib-src directory

The problem is that the code as written actually returns a zero (0) exit code for the test ! -f "site-lib-src/$$x/META" command no matter what in my MacOS Catalina (I originally said Monterey above, sorry)

So is the intent to just get those three?

Again, I'll file an issue with ocamlfind
