This is the .NET 8.0 package for Alpine Linux.
|
|
|
|
Please report any issues [using Gitlab](https://gitlab.alpinelinux.org/alpine/aports/-/issues/new) and tag @ayakael

# Building info
|
|
|
|
## Generated packages
|
|
* `aspnetcore8-runtime`
|
|
* `aspnetcore8-targeting-pack`
|
|
* `dotnet8-apphost-pack` (used by dotnet8-runtime)
|
|
* `dotnet8-hostfxr` (used by dotnet-host)
|
|
* `dotnet8-runtime`
|
|
* `dotnet8-targeting-pack`
|
|
* `dotnet-host`
|
|
|
|
## How to build dotnet8 on Alpine
|
|
As dotnet is a self-hosting compiler (thus it compiles using itself), it
|
|
requires a bootstrap for the initial build. To solve this problem, this package
|
|
follows the `stage0` proposal outlined [here](https://lists.alpinelinux.org/~alpine/devel/%3C33KG0XO61I4IL.2Z7RTAZ5J3SY6%408pit.net%3E)
|
|
|
|
The goal of `stage0` is to bootstrap dotnet with as little intervention as
|
|
possible, thus allowing seamless Alpine upgrades. Unfortunately, upstream only
|
|
builds bootstraps for Alpine on `x86_64`, `aarch64`, and `armv7`. Thus, `stage0`
|
|
has also been designed to be crossbuild aware, allowing bootstrapping to other
|
|
platforms.
|
|
|
|
In summary, dotnet8 is built using three different aports.
|
|
|
|
* `community/dotnet8-stage0`
|
|
Builds minimum components for full build of dotnet8, and packages these in an initial
|
|
`dotnet8-stage0-bootstrap` package that `dotnet8-build` pulls.
|
|
* `community/dotnet8-build`
|
|
Builds full and packages dotnet8 fully using either stage0 or previoulsy built
|
|
dotnet8 build.
|
|
* `community/dotnet8-runtime`
|
|
As abuild does not allow different versions for subpackages, a different aport
|
|
is required to package runtime bits from dotnet8-build.
|
|
|
|
## Crossbuilding with `stage0`
|
|
Crossbuilding `stage0` is a three step process:
|
|
1. Build sysroot for target platform by using `scripts/bootstrap.sh` in aports repo:
|
|
```
|
|
./bootstrap.sh $CTARGET_ARCH
|
|
```
|
|
2. Although not necessary, it is recommended to add Alpine repositories to
|
|
`$HOME/sysroot-$CTARGET_ARCH/etc/apk/repositories`, making sure to add required
|
|
keys. This makes it so that whatever package is not built in step 1 will
|
|
be pulled from package repos
|
|
3. Crossbuild `dotnet8-stage0` via:
|
|
```
|
|
CHOST=$CTARGET_ARCH abuild -r
|
|
```
|
|

# Specification
|
|
|
|
This package follows [package naming and contents suggested by upstream](https://docs.microsoft.com/en-us/dotnet/core/build/distribution-packaging),
|
|
with two exceptions. It installs dotnet to `/usr/lib/dotnet` (aka `$_libdir`).
|
|
In addition, the package is named `dotnet8` as opposed to `dotnet-8.0`
|
|
to match Alpine Linux naming conventions for packages with many installable versions
|
|

# Contributing
|
|
|
|
The steps below are for the final package. Please only contribute to a
|
|
pre-release version if you know what you are doing. Original instructions
|
|
follow.
|
|
|
|
## General Changes
|
|
|
|
1. Fork the main aports repo.
|
|
|
|
2. Checkout the forked repository.
|
|
|
|
- `git clone ssh://git@gitlab.alpinelinux.org/$USER/aports`
|
|
- `cd community/dotnet8-build`
|
|
|
|
3. Make your changes. Don't forget to add a changelog.
|
|
|
|
4. Do local builds.
|
|
|
|
- `abuild -r`
|
|
|
|
5. Fix any errors that come up and rebuild until it works locally.
|
|
|
|
6. Commit the changes to the git repo in a git branch
|
|
|
|
- `git checkout -b dotnet8/<name>`
|
|
- `git add` any new patches
|
|
- `git remove` any now-unnecessary patches
|
|
- `git commit -m 'community/dotnet8-build: descriptive description'`
|
|
- `git push`
|
|
|
|
7. Create a merge request with your changes, tagging @ayakael for review.
|
|
|
|
8. Once the tests in the pull-request pass, and reviewers are happy, your changes
|
|
will be merged.
|
|
|
|
## Updating to an new upstream release
|
|
|
|
1. Fork the main aports repo.
|
|
|
|
2. Checkout the forked repository.
|
|
|
|
- `git clone ssh://git@gitlab.alpinelinux.org/$USER/aports`
|
|
- `cd community/dotnet8-build`
|
|
|
|
|
|
3. Build the new upstream source tarball. Update the versions in the
|
|
APKBUILD file, and then create a snapshot. After build, update checksum.
|
|
|
|
- `abuild snapshot`
|
|
- `abuild checksum`
|
|
|
|
4. Do local builds.
|
|
|
|
- `abuild -r`
|
|
|
|
5. Fix any errors that come up and rebuild until it works locally. Any
|
|
patches that are needed at this point should be added to the APKBUILD file
|
|
in `_patches` variable.
|
|
|
|
6. Upload the source archive to a remote location, and update `source` variable.
|
|
|
|
7. Commit the changes to the git repo in a git branch.
|
|
|
|
- `git checkout -b dotnet8/<name>`
|
|
- `git add` any new patches
|
|

|
|

|
|
- `git push`
|
|
|
|

|
|
|
|
9. Once the tests in the pull-request pass, and reviewers are happy, your changes
|
|
will be merged.
|

|
# Testing
|
|
|
|
This package uses CI tests as defined in `check()` function. Creating a
|
|
merge-request or running a build will fire off tests and flag any issues.
|
|
|
|
The tests themselves are contained in this external repository:
