Binaries of this type must be executable on the current 12 :: system, so the only common reason to set this is to set 13 :: GOHOSTARCH=386 on an amd64 machine. 14 :: 15 :: GOARCH: The target architecture for installed packages and tools. 16 :: 17 :: GOOS: The target operating system for installed packages and tools. 18 :: 19 :: GO_GCFLAGS: Additional go tool compile arguments to use when 20 :: building the packages and commands. 21 :: 22 :: GO_LDFLAGS: Additional go tool link arguments to use when 23 :: building the commands. 24 :: 25 :: CGO_ENABLED: Controls cgo usage during the build. Set it to 1 26 :: to include all cgo related files, .c and .go file with "cgo" 27 :: build directive, in the build. Set it to 0 to ignore them. 28 :: 29 :: CC: Command line to run to compile C code for GOHOSTARCH. 30 :: Default is "gcc". 31 :: 32 :: CC_FOR_TARGET: Command line to run compile C code for GOARCH. 33 :: This is used by cgo. Default is CC. 34 :: 35 :: FC: Command line to run to compile Fortran code. 36 :: This is used by cgo.
