| # Environment variables that control make.bash: |
| # |
| # 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 5g/6g/8g arguments to use when |
| # building the packages and commands. |
| # |
| # GO_LDFLAGS: Additional 5l/6l/8l arguments to use when |
| # building the commands. |
| # |
| # GO_CCFLAGS: Additional 5c/6c/8c arguments to use when |
| # building. |
| # |
| # 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. |
| # |
| # GO_EXTLINK_ENABLED: Set to 1 to invoke the host linker when building |
| # packages that use cgo. Set to 0 to do all linking internally. This |
| # controls the default behavior of the linker's -linkmode option. The |
| # default value depends on the system. |
| # |
| # CC: Command line to run to compile C code for GOHOSTARCH. |
| # Default is "gcc". Also supported: "clang". |
| # |
| # CC_FOR_TARGET: Command line to run to compile C code for GOARCH. |
| # This is used by cgo. Default is CC. |
| # |
| # CXX_FOR_TARGET: Command line to run to compile C++ code for GOARCH. |
| # This is used by cgo. Default is CXX, or, if that is not set, |
| # "g++" or "clang++". |
| # |
| # GO_DISTFLAGS: extra flags to provide to "dist bootstrap". Use "-s" |
| # to build a statically linked toolchain. |
