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 # GO_EXTLINK_ENABLED: Set to 1 to invoke the host linker when building 30 # packages that use cgo. Set to 0 to do all linking internally. This 31 # controls the default behavior of the linker's -linkmode option. The 32 # default value depends on the system. 33 # 34 # GO_LDSO: Sets the default dynamic linker/loader (ld.so) to be used 35 # by the internal linker. 36 # 37 # CC: Command line to run to compile C code for GOHOSTARCH. 38 # Default is "gcc". Also supported: "clang". 39 # 40 # CC_FOR_TARGET: Command line to run to compile C code for GOARCH. 41 # This is used by cgo. Default is CC. 42 # 43 # CC_FOR_${GOOS}_${GOARCH}: Command line to run to compile C code for specified ${GOOS} and ${GOARCH}. 44 # (for example, CC_FOR_linux_arm) 45 # If this is not set, the build will use CC_FOR_TARGET if appropriate, or CC. 46 # 47 # CXX_FOR_TARGET: Command line to run to compile C++ code for GOARCH. 48 # This is used by cgo. Default is CXX, or, if that is not set, 49 # "g++" or "clang++". 50 # 51 # CXX_FOR_${GOOS}_${GOARCH}: Command line to run to compile C++ code for specified ${GOOS} and ${GOARCH}. 52 # (for example, CXX_FOR_linux_arm) 53 # If this is not set, the build will use CXX_FOR_TARGET if appropriate, or CXX. 54 # 55 # FC: Command line to run to compile Fortran code for GOARCH. 56 # This is used by cgo. Default is "gfortran". 57 # 58 # PKG_CONFIG: Path to pkg-config tool. Default is "pkg-config". 59 # 60 # GO_DISTFLAGS: extra flags to provide to "dist bootstrap". 61 # (Or just pass them to the make.bash command line.) 62 # 63 # GOBUILDTIMELOGFILE: If set, make.bash and all.bash write 64 # timing information to this file.
