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 # 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 # CXX_FOR_TARGET: Command line to run to compile C++ code for GOARCH. 44 # This is used by cgo. Default is CXX, or, if that is not set, 45 # "g++" or "clang++". 46 # 47 # FC: Command line to run to compile Fortran code for GOARCH. 48 # This is used by cgo. Default is "gfortran". 49 # 50 # PKG_CONFIG: Path to pkg-config tool. Default is "pkg-config". 51 # 52 # GO_DISTFLAGS: extra flags to provide to "dist bootstrap". 53 # (Or just pass them to the make.bash command line.) 54 # 55 # GOBUILDTIMELOGFILE: If set, make.bash and all.bash write 56 # timing information to this file. Useful for profiling where the 57 # time goes when these scripts run. 58 # 59 # GOROOT_BOOTSTRAP: A working Go tree >= Go 1.4 for bootstrap. 60 # If $GOROOT_BOOTSTRAP/bin/go is missing, $(go env GOROOT) is 61 # tried for all "go" in $PATH. $HOME/go1.4 by default. 62 63 set -e 64 65 unset GOBIN # Issue 14340 66 unset GOFLAGS 67 unset GO111MODULE 68 69 70 if [ ! -f run.bash ]; then 71 echo 'make.bash must be run from $GOROOT/src' 1>&2 72 exit 1 73 fi 74 75 if [ "$GOBUILDTIMELOGFILE" != "" ]; then 76 echo $(LC_TIME=C date) start make.bash >"$GOBUILDTIMELOGFILE" 77 fi 78 79 # Test for Windows. 80 case "$(uname)" in 81 *MINGW* | *WIN32* | *CYGWIN*) 82 echo 'ERROR: Do not use make.bash to build on Windows.' 83 echo 'Use make.bat instead.' 84 echo 85 exit 1 86 ;; 87 esac 88 89 # Test for bad ld. 90 if ld --version 2>&1 | grep 'gold.* 2\.20' >/dev/null; then 91 echo 'ERROR: Your system has gold 2.20 installed.' 92 echo 'This version is shipped by Ubuntu even though' 93 echo 'it is known not to work on Ubuntu.' 94 echo 'Binaries built with this linker are likely to fail in mysterious ways.' 95 echo 96 echo 'Run sudo apt-get remove binutils-gold.' 97 echo 98 exit 1 99 fi 100 101 # Test for bad SELinux. 102 # On Fedora 16 the selinux filesystem is mounted at /sys/fs/selinux, 103 # so loop through the possible selinux mount points. 104 for se_mount in /selinux /sys/fs/selinux 105 do 106 if [ -d $se_mount -a -f $se_mount/booleans/allow_execstack -a -x /usr/sbin/selinuxenabled ] && /usr/sbin/selinuxenabled; then 107 if ! cat $se_mount/booleans/allow_execstack | grep -c '^1 1$' >> /dev/null ; then 108 echo "WARNING: the default SELinux policy on, at least, Fedora 12 breaks " 109 echo "Go.
