# Tezos on NetBSD

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

## Problems with possible solutions

1. 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

2. 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?

```

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

4. GMP fix

Cannot find GMP where it expects.

```
zen: {343} setenv CFLAGS -I/usr/pkg/include
zen: {344} opam install conf-gmp --verbose
zen: {345} eval `opam env`
```

5. 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 -D__FreeBSD__ 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

help: consider importing this struct

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

## Process

I will update this as I go.

0. 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.

1. Install prerequisites
pkgin install gmake ocaml-opam jq git libev libhidapi autoconf

2. Get Rust

3. Get the Tezos sources

setenv C_INCLUDE_PATH /usr/pkg/include:/usr/pkg/include/ev
setenv LIBRARY_PATH /usr/pkg/lib:/usr/pkg/lib/ev
#setenv CFLAGS "-I/usr/pkg/include -D__FreeBSD__ -fPIC"
setenv CFLAGS -I/usr/pkg/include 

4. init --bare
gmake build-deps

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

gmake build-deps

- class_group_vdf ** Cannot find gmpxx.h library **
