Opam 2.2.1 release - install broken on (latest) OpenBSD 7.6

[jideelgh]

Just to let you know, trying to install Opam 2.2.1 release on OpenBSD 7.6 (using bash -c "sh <(curl -fsSL https://opam.ocaml.org/install.sh)" which fetches opam-2.2.1-x86_64-openbsd) leads to:

ld.so: opam: can't load library 'libc++.so.9.0'
Killed

OpenBSD moved to libc++.so.10.0 in 7.5:

tar -tzf base73.tgz |grep libc++
./usr/lib/libc++.so.9.0
./usr/lib/libc++abi.so.6.0

tar -tzf base74.tgz |grep libc++
./usr/lib/libc++.so.9.0
./usr/lib/libc++abi.so.6.0

tar -tzf base75.tgz |grep libc++
./usr/lib/libc++.so.10.0
./usr/lib/libc++abi.so.7.0

So I guess I was just 'lucky' to keep libc++.so.9.0 during the previous upgrades but on an upgraded 7.5->7.6 system which still has 'libc++.so.9.0' available, it's not anymore sufficient:

opam[31192]: pinsyscalls addr ca14a7fb859 code 253, pinoff 0xffffffff (pin 330 ca1c28c5000-ca1c28d366d e66d) (libcpin 0 0-0 0) error 78
Abort trap

I managed to workaround this by :

• pkg_add opam which installs opam 2.2.0 (and is built against libc++.so.10.0)
• build opam 2.2.1 from source.
• remove 2.2.0 afterwards.

Not so much a big deal but at least you're aware of this 'issue'.

I think this should be moved to ocaml/opam. Ping @kit-ty-kate or @rjbou

#6237 fixed this (only >= 2.3.0~beta1), however the release binary now is only available for OpenBSD 7.6. I'll open a new ticket to remind myself to experiment with statically linked binaries on OpenBSD to see if it could be a solution for 7.5 as OpenBSD supports its last two releases (7.5 and 7.6).
