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. 31 # 32 # GO_EXTLINK_ENABLED: Set to 1 to invoke the host linker when building 33 # packages that use cgo. Set to 0 to do all linking internally. This 34 # controls the default behavior of the linker's -linkmode option. The 35 # default value depends on the system. 36 # 37 # GO_LDSO: Sets the default dynamic linker/loader (ld.so) to be used 38 # by the internal linker. 39 # 40 # CC: Command line to run to compile C code for GOHOSTARCH. 41 # Default is "gcc". Also supported: "clang". 42 # 43 # CC_FOR_TARGET: Command line to run to compile C code for GOARCH. 44 # This is used by cgo. Default is CC. 45 # 46 # CC_FOR_${GOOS}_${GOARCH}: Command line to run to compile C code for specified ${GOOS} and ${GOARCH}. 47 # (for example, CC_FOR_linux_arm) 48 # If this is not set, the build will use CC_FOR_TARGET if appropriate, or CC. 49 # 50 # CXX_FOR_TARGET: Command line to run to compile C++ code for GOARCH. 51 # This is used by cgo. Default is CXX, or, if that is not set, 52 # "g++" or "clang++". 53 # 54 # CXX_FOR_${GOOS}_${GOARCH}: Command line to run to compile C++ code for specified ${GOOS} and ${GOARCH}. 55 # (for example, CXX_FOR_linux_arm) 56 # If this is not set, the build will use CXX_FOR_TARGET if appropriate, or CXX. 57 # 58 # FC: Command line to run to compile Fortran code for GOARCH. 59 # This is used by cgo. Default is "gfortran". 60 # 61 # PKG_CONFIG: Path to pkg-config tool. Default is "pkg-config". 62 # 63 # GO_DISTFLAGS: extra flags to provide to "dist bootstrap". 64 # (Or just pass them to the make.bash command line.) 65 # 66 # GOBUILDTIMELOGFILE: If set, make.bash and all.bash write 67 # timing information to this file. Useful for profiling where the 68 # time goes when these scripts run. 69 # 70 # GOROOT_BOOTSTRAP: A working Go tree >= Go 1.17.13 for bootstrap. 71 # If $GOROOT_BOOTSTRAP/bin/go is missing, $(go env GOROOT) is 72 # tried for all "go" in $PATH.
