# 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.

|
# building the commands.

# CGO_ENABLED: Setting this to 0 disables the use of cgo
