8 # Environment variables that control make.rc:
9 #
10 # GOROOT_FINAL: The expected final Go root, baked into binaries.
11 # The default is the location of the Go tree during the build.
12 #
13 # GOHOSTARCH: The architecture for host tools (compilers and
14 # binaries). Binaries of this type must be executable on the current
15 # system, so the only common reason to set this is to set
16 # GOHOSTARCH=386 on an amd64 machine.
17 #
18 # GOARCH: The target architecture for installed packages and tools.
19 #
20 # GOOS: The target operating system for installed packages and tools.
21 #
22 # GO_GCFLAGS: Additional go tool compile arguments to use when
23 # building the packages and commands.
24 #
25 # GO_LDFLAGS: Additional go tool link arguments to use when
26 # building the commands.
27 #
28 # CGO_ENABLED: Controls cgo usage during the build. Set it to 1
29 # to include all cgo related files, .c and .go file with "cgo"
30 # build directive, in the build. Set it to 0 to ignore them.
