| # Environment variables that control make.rc: |
| # |
| # GOROOT_FINAL: The expected final Go root, baked into binaries. |
| # The default is the location of the Go tree during the build. |
| # |
| # GOHOSTARCH: The architecture for host tools (compilers and |
| # binaries). Binaries of this type must be executable on the current |
| # system, so the only common reason to set this is to set |
| # GOHOSTARCH=386 on an amd64 machine. |
| # |
| # GOARCH: The target architecture for installed packages and tools. |
| # |
| # GOOS: The target operating system for installed packages and tools. |
| # |
| # GO_GCFLAGS: Additional go tool compile arguments to use when |
| # building the packages and commands. |
| # |
| # GO_LDFLAGS: Additional go tool link arguments to use when |
| # building the commands. |
| # |
| # CGO_ENABLED: Controls cgo usage during the build. Set it to 1 |
| # to include all cgo related files, .c and .go file with "cgo" |
| # build directive, in the build. Set it to 0 to ignore them. |
