The example based on my notes is quite straight-forward:
```
depends=(
glibc
)
makedepends=(
zig
)
build() {
cd "${pkgname}-${pkgver}"
zig build --verbose -Dcpu=baseline -Doptimize=ReleaseSmall
}
package() {
cd "${pkgname}-${pkgver}"
install -Dm755 -t "${pkgdir}/usr/bin" zig-out/bin/example
}
```
Common gotchas were:
- The `zig build` command is essentially fully silent if no interactive
terminal is attached, `--verbose` helped but it's still very little info
- Without `-Dcpu=baseline` the compiler is going to probe the build
server cpu, which both causes problems with Reproducible Builds, but
more importantly can also make the binary crash with `Illegal
instruction` errors, since the default binaries aren't really distributable
Looking at the ncdu PKGBUILD shows there's some room for improvement:
```
build() {
cd "${pkgname}-${pkgver}"
DESTDIR="build" zig build \
--summary all \
--global-cache-dir ../zig-global-cache \
--prefix /usr \
--search-prefix /usr \
--release=safe \
-Dtarget=native-linux.6.1-gnu.2.38 \
-Dcpu=baseline \
-Dpie=true
}
check() {
cd "${pkgname}-${pkgver}"
zig build test \
--summary all \
--global-cache-dir ../zig-global-cache \
--prefix /usr \
--search-prefix /usr \
--release=safe \
-Dtarget=native-linux.6.1-gnu.2.38 \
-Dcpu=baseline \
-Dpie=true
}
```
More input very welcome, but I'm also fine with adding a very basic one
by myself and whoever has something to add can just edit the wiki.
I've been the defacto zig package maintainer for a bit now.
Good packages to look at are ncdu, river, waylock.
Guidelines off the top of my head:
- Indeed make sure you don't forget `-Dcpu=baseline`
- zig targets include a kernel version and glibc version; make sure
you include them!
- Leave the target architecture as `native` so that archlinuxarm can
pick up the package automatically
- Add build.zig.zon dependencies to the `sources` array so they get
archived correctly; they also need to be added to `noextract`
We should probably write a script to automate this.
- Use prepare() to build a build-environment-local global package cache
- Use `--system ../zig-global-cache/p` to then use that package cache
- Consider `--summary all` to get some build output
- `package()` should usually be `cp -a build/* "$pkgdir` rather than
trying to `install` files individually
