Tezos on NetBSD

Some notes on getting Octez to compile on NetBSD. Work in progress.

Problems with possible solutions

Opam package doesn't include solver properly.

Three ways:

Add lib-ext to targets and run before all (which isn't working for me)
Is there another way to include the solver at runtime?
Builds natively - accept that we have to do this outside of pkgsrc
Once Opam is installed, it cannot compile OCaml on arm64 platforms (and probably others). Amd64 is fine.

OCaml builds in pkgsrc. Submit our pkgsrc patches back to OCaml team?

HACL Star library explicitly excludes NetBSD Patch done. FreeBSD settings work. Sent to vdum.
GMP fix

Cannot find GMP where it expects.

Zarith 1.12

Zarith hackery 1.13 works out of the box. We seem to require 1.12?

cd ../
mkdir zarith-1.12
ftp -a https://github.com/ocaml/Zarith/archive/release-1.13.tar.gz
cd zarith-1.12/
tar zxvf ../release-1.13.tar.gz
zen: {363} cd ../../tezos/
zen: {364} pwd
/home/cjep/src/tezos
zen: {365} opam install ../zarith-1.12/Zarith-release-1.13

mirage-crypto-rng FreeBSD definition line in sources - needs NetBSD too! Add -DFreeBSD as a workaround

pringo.1.3 popcount function conflicts with native one I worked around by renaming it - what is the best way normally?

pyml pyml_arch.ml.c checks for unix. We have unix Pull request submitted to pyml https://github.com/thierry-martinez/pyml/pull/99

tezos-rust-libs.1.6

disc space error in /tmp. /tmp needs at least 906M free drwxrwxrwt 6 root wheel 384 Jan 27 15:32 tmp
error[E0412]: cannot find type QueryIter in module os --> /home/cjep/src/tezos/_opam/.opam-switch/build/tezos-rust-libs.1.6/vendor/region/src/qu ery.rs:7:24 | 7 | iterator: Option, | ^^^^^^^^^ not found in os | help: consider importing this struct

Repeatedly wanting to install autoconf. Has to be a path issue

Process

I will update this as I go.

Make sure /tmp has at least 1G available otherwise tezos-rust-libs cannot start to compile. On older machines /tmp is often in RAM to speed up.
Install prerequisites pkgin install gmake ocaml-opam jq git libev libhidapi autoconf

Fix ups: opam install ../fixed up - hacl-star-raw needs the patch - pringo function fix - pyml - mirage-crypto-rng -DFreeBSD - zarith (install 13 instead of 12)
