of writing for example river is compatible with Zig 0.9.0 and 0.9.1 but
not Zig 0.8.0 or 0.10.0.
## Zig Package Manager
River uses the built-in Zig package manager for its (few) Zig dependencies.
By default, running `zig build` will fetch river's Zig dependencies from the
internet and store them in the global zig cache before building river. Since
accessing the internet is forbidden or at least frowned upon by most distro
packaging infrastructure, there are ways to fetch the Zig dependencies in a
separate step before building river:
1. Fetch step with internet access:
For each package in the `build.zig.zon` manifest file run the following command
with the tarball URL in the `build.zig.zon`:
```
zig fetch --global-cache-dir /tmp/foobar $URL
```
This command will download and unpack the tarball, hash the contents of the
tarball, and store the contents in the `/tmp/foobar/p/$HASH` directory. This
hash should match the corresponding hash field in the `build.zig.zon`.
2. Build step with no internet access:
The `--system` flag for `zig build` takes a path to an arbitrary directory in
which zig packages stored in subdirectories matching their hash can be found.
```
zig build --system /tmp/foobar/p/ ...
```
This flag will disable all internet access and error if a package is not found
in the provided directory.
It is also possible for distros to distribute Zig package manager packages as
distro packages, although there are still some rough edges as the support for
this is not yet mature. See this patchset for Chimera Linux for an example of
how this can work: https://github.com/chimera-linux/cports/pull/1395
