setup-cgo

A GitHub Action that installs the C cross compiler for a Go target and sets CC, CXX and CGO_ENABLED=1, so go build links cgo packages such as SQLite for that target. It covers the targets Nginx UI is released for and uses the same toolchains as its release builds.

Targets

GOOS	GOARCH	Toolchain	Runner
linux	386, amd64, arm64, arm (GOARM 5, 6, 7), riscv64, loong64, mips, mipsle, mips64, mips64le	musl cross compilers from musl-cross-compilers, statically linked	x64 Linux
windows	386, amd64	MinGW-w64 from the Ubuntu packages	x64 Linux
windows	arm64	llvm-mingw, checked against its digest	x64 Linux
darwin	amd64, arm64	the clang of the runner	macOS

An empty goarm means GOARM 7, Go's default. The musl toolchain download is tried three times, it fails now and then.

Outputs

Output	Value
cc, cxx	The compilers, also exported as CC and CXX.
extldflags	Flags for the external linker: -static on Linux, empty elsewhere.
triple	The target triple of the toolchain.
