@caseyjp1 It's not a problem with the build. Read the error message. You have updated ocaml since the last time you compiled this package so you need to recompile all the dependencies. Use "pacman -Qo [.cmi filename]" to find which packages to rebuild. Or if you're brave, pacman -Rsc gapi-ocaml && pacman -Sc and start from scratch.

I also got the error. I found that ocaml-curl installs its files in /usr/lib/curl/. However, ocamlfind only searches for packages in /usr/lib/ocaml/ by default.

There are two relatively straightforward methods to resolve this issue.

The first method involves modifying the build() function in gapi-ocaml's PKGBUILD as follows:

build() {
    cd "${srcdir}/${pkgname}-${pkgver}"

export OCAMLPATH="/usr/lib:/usr/lib/ocaml"

    dune build -p "$pkgname"

    sed -i '/doc:\s\[/,$d' _build/default/gapi-ocaml.install
}

However, this requires manually modifying the build() section after every gapi-ocaml update until the packager fixes the PKGBUILD.

The second method is to manually create symbolic links so ocamlfind can find what it needs:

sudo ln -s /usr/lib/curl /usr/lib/ocaml/curl

sudo ln -s /usr/lib/ocurl /usr/lib/ocaml/ocurl

sudo ln -s /usr/lib/curl_lwt /usr/lib/ocaml/curl_lwt

This is the safest approach, preventing ocamlfind from scanning the entire /usr/lib directory.

Anyone else getting this:

For those encountering the following error while building gapi-ocaml, you can manually edit the version in the PKGBUILD of ocaml-cryptokitin AUR to 1.20 or below.

Aborting...

This is because Cryptokit 1.21 introduced an RSA change that broke the RSA functionality required by gapi-ocaml. This PR migrates Cryptokit's big-number arithmetic core from the legacy Numerix library to Zarith. This means: if the build environment fails to correctly detect Zarith, Cryptokit may either omit compiling the RSA module entirely (since RSA relies on big-number arithmetic) or produce a broken interface.

Please fix the dependency, remove: 'ocaml-yojson<2.0.0' and replace it with: 'ocaml-yojson'.

Version 0.4.3 supports yojson 2.0.0 and up, see this closed issue: https://github.com/astrada/gapi-ocaml/issues/43

Also, about ocaml-cryptokit, see my last comment on https://aur.archlinux.org/packages/ocaml-cryptokit. This can also be fixed, but you need to modify the PKGBUILD yourself, since the maintainer is not responding.

I do : Or if you're brave, pacman -Rsc gapi-ocaml && pacman -Sc and start from scratch.

It don't result.

 -> Error:
    ocaml-yojson<2.0.0 (Need: gapi-ocaml)

Can we do it? I think no.

'ocaml-yojson>=1.6.0'
'ocaml-yojson<2.0.0'

and aur has only ocaml-cryptokit < 1.3

Sorry. I don't know how do it right.

If you are experiencing problems with upgrading because of ocaml-yojson which is already version 2.x in the AUR, and this package still requires a version < 2.0, you can upgrade to 0.4.3 which fixes this problem. The following PKGBUILD works just fine:

@Glitchyme I changed the ocaml lib ownership but I also had to modify the PKGBUILD package() cause 'dune' kept asking for dir definitions, so I changed it from this:

package() {
  cd ${srcdir}/${pkgname}-${pkgver}
  export OCAMLFIND_DESTDIR="$pkgdir/$(ocamlfind printconf destdir)"
  install -dm755 "$OCAMLFIND_DESTDIR"

  dune install 
}

package() {
  cd ${srcdir}/${pkgname}-${pkgver}
  export OCAMLFIND_DESTDIR="$pkgdir/$(ocamlfind printconf destdir)"
  install -dm755 "$OCAMLFIND_DESTDIR"

  dune install --mandir /usr/share/man --docdir=/usr/share/doc --etcdir=/etc --datadir=/usr/data --sbindir=/usr/sbin --bindir=/usr/bin
}

Since I use 'yay' to manage aur packages, it was tricky to modify the PKGBUILD (if anyone knows how I would be grateful), but after all, that worked.

@webdawg does installing through opam work in the meantime? opam install gapi-ocaml

If not you can get around it the same way I did (though probably not recommended):

sudo chown -R user:user /usr/lib/ocaml # temporarily own for your user
yay -S gapi-ocaml
sudo chown -R root:root /usr/lib/ocaml # set back to root
