\r
7 :: GOROOT_FINAL: The expected final Go root, baked into binaries.
\r
8 :: The default is the location of the Go tree during the build.
\r
10 :: GOHOSTARCH: The architecture for host tools (compilers and
\r
11 :: binaries). Binaries of this type must be executable on the current
\r
12 :: system, so the only common reason to set this is to set
\r
13 :: GOHOSTARCH=386 on an amd64 machine.
\r
15 :: GOARCH: The target architecture for installed packages and tools.
\r
17 :: GOOS: The target operating system for installed packages and tools.
\r
19 :: GO_GCFLAGS: Additional go tool compile arguments to use when
\r
20 :: building the packages and commands.
\r
22 :: GO_LDFLAGS: Additional go tool link arguments to use when
\r
23 :: building the commands.
\r
25 :: CGO_ENABLED: Controls cgo usage during the build. Set it to 1
\r
26 :: to include all cgo related files, .c and .go file with "cgo"
\r
27 :: build directive, in the build. Set it to 0 to ignore them.
\r
29 :: CC: Command line to run to compile C code for GOHOSTARCH.
\r
30 :: Default is "gcc".
\r
32 :: CC_FOR_TARGET: Command line to run compile C code for GOARCH.
\r
33 :: This is used by cgo. Default is CC.
\r
35 :: FC: Command line to run to compile Fortran code.
\r
36 :: This is used by cgo. Default is "gfortran".
