Building OCaml 5

[anzhi0708]

OCaml 4.07.1 is available through its-pointless repo, yet it's an outdated version which does not support multi-threading.

The OCaml package manager, OPAM, is also available via the repo mentioned above.

But if you try to install OCaml 5 on native Termux (not proot-distro linux) with opam switch create 5.0.0, installation will fail.

If you want to try the new multicore version OCaml like I do, here's how you do it.

apt install libandroid-shmem

git clone https://github.com/ocaml/ocaml

Then cd ocaml, modify the configure.ac like this:

configure.ac

Then

make configure

./configure --prefix=$PREFIX --disable-warn-error --without-afl LDFLAGS="-landroid-shmem"

And finally

make install
