# Build versioned application binaries
|
|
|
|
Use `releasekit.Build` when an application needs binaries for explicit Go
|
|
operating-system and architecture pairs:
|
|
|
|
```go
|
|
import (
|
|
"context"
|
|
"fmt"
|
|
|
|
releasekit "gitea.maximumdirect.net/eric/ReleaseKit"
|
|
)
|
|
|
|
func build(ctx context.Context) error {
|
|
result, err := releasekit.Build(ctx, releasekit.BuildRequest{
|
|
RepositoryDir: "/work/project",
|
|
Version: "v1.2.3",
|
|
Spec: releasekit.BuildSpec{
|
|
MainPackage: "./cmd/project",
|
|
BinaryName: "project",
|
|
Targets: []releasekit.Target{
|
|
{OS: "linux", Arch: "amd64"},
|
|
{OS: "linux", Arch: "arm64"},
|
|
{OS: "darwin", Arch: "arm64"},
|
|
},
|
|
},
|
|
OutputDir: "dist",
|
|
})
|
|
if err != nil {
|
|
return err // result retains completed artifacts when a later step fails.
|
|
}
|
|
for _, artifact := range result.Artifacts {
|
|
fmt.Println(artifact.Filename, artifact.SHA256)
|
|
}
|
|
return nil
|
|
}
|
|
```
|
|
|
|
`Build` records the repository's current `HEAD`, injects the selected stable
|
|
version into `buildinfo.Version`, and returns the compiler identity, normalized
|
|
targets, artifact paths, filenames, and SHA-256 digests. Names follow
|
|
`<binary>-<version>-<goos>-<goarch>`; Windows targets add `.exe`. A repeated
|
|
target pair is built once, at its first position. Local builds may use modified
|
|
source. `SourceVerified` is true only after a complete build observes clean
|
|
source and the same HEAD before and after compilation; binary delivery requires
|
|
that fact. This observation is not a source snapshot or attestation guarantee.
|
|
|
|
The default output directory is `<repository>/dist`; a relative `OutputDir` is
|
|
resolved from the repository. Selected artifact filenames are regenerated. Other files in the output
|
|
directory are left in place. A failed later build or native version check returns the binaries already
|
|
generated in `BuildResult.Artifacts`.
|
|
|
|
Builds use the prepared local Go toolchain, readonly module mode, disabled
|
|
module network access, `CGO_ENABLED=0`, `-trimpath`, and `-buildvcs=false`. Each
|
|
selected target is compiled explicitly. ReleaseKit then runs the `version`
|
|
command on a native binary and requires `<binary> <version>` followed by a
|
|
newline. If no selected target matches the Go host, it builds a temporary
|
|
native binary for this check and removes it afterward. Cross-compilation does
|
|
not promise that a binary runs on another platform.
|
|
|
|
An empty target list records the source commit and returns without invoking Go,
|
|
creating the output directory, or running a version check. It does not require a
|
|
main package or binary name. This supports source-only operations without
|
|
silently adding a binary check.
|
|
|
|
The [`build` command](../cli.md) reads the same build specification from the
|
|
profile and writes a private receipt alongside its artifacts. `check` and
|
|
`publish` run selected builds after their one validation callback using
|
|
temporary output outside the worktree; those candidate checks do not write a
|
|
receipt or leave build files in the repository.
|
|
|
|
For delivery from a tagged checkout, `deliver` builds selected tagged-source
|
|
targets into temporary storage by default. Use `--assets DIR` to deliver a
|
|
separate build output; ReleaseKit requires its receipt and verifies the source,
|
|
build settings, and artifact hashes before the first Gitea write. See the
|
|
[delivery consumer guide](delivery.md) for page-only delivery and retry states.
