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 rfork e 33 if(! test -f run.rc){ 34 echo 'make.rc must be run from $GOROOT/src' >[1=2] 35 exit wrongdir 36 } 37 38 # Clean old generated file that will cause problems in the build. 39 rm -f ./runtime/runtime_defs.go 40 41 # Determine the host compiler toolchain. 42 eval `{grep '^(CC|LD|O)=' /$objtype/mkfile} 43 44 vflag=() 45 if(~ $1 -v) { 46 vflag=(-v) 47 shift 48 } 49 50 fn nogoenv { 51 GO111MODULE=off GOENV=off GOOS=() GOARCH=() GOEXPERIMENT=() GOFLAGS=() $* 52 } 53 54 bootgo = 1.17.13 55 GOROOT = `{cd .. && pwd} 56 goroot_bootstrap_set = 'true' 57 if(! ~ $#GOROOT_BOOTSTRAP 1){ 58 goroot_bootstrap_set = 'false' 59 GOROOT_BOOTSTRAP = $home/go1.4 60 for(d in sdk/go$bootgo go$bootgo) 61 if(test -d $home/$d) 62 GOROOT_BOOTSTRAP = $home/$d 63 } 64 for(p in $path){ 65 if(! test -x $GOROOT_BOOTSTRAP/bin/go){ 66 if(go_exe = `{path=$p whatis go}){ 67 goroot = `{GOROOT=() nogoenv $go_exe env GOROOT} 68 if(! ~ $goroot $GOROOT){ 69 if(~ $goroot_bootstrap_set 'true'){ 70 echo 'WARNING: '$GOROOT_BOOTSTRAP'/bin/go does not exist, found '$go_exe' from env' >[1=2] 71 echo 'WARNING: set '$goroot' as GOROOT_BOOTSTRAP' >[1=2] 72 } 73 GOROOT_BOOTSTRAP = $goroot 74 } 75 } 76 } 77 } 78 if(! test -x $GOROOT_BOOTSTRAP/bin/go){ 79 echo 'ERROR: Cannot find '$GOROOT_BOOTSTRAP'/bin/go.' >[1=2] 80 echo 'Set $GOROOT_BOOTSTRAP to a working Go tree >= Go '$bootgo'.' >[1=2] 81 exit bootstrap 82 } 83 if(~ $GOROOT_BOOTSTRAP $GOROOT){ 84 echo 'ERROR: $GOROOT_BOOTSTRAP must not be set to $GOROOT' >[1=2] 85 echo 'Set $GOROOT_BOOTSTRAP to a working Go tree >= Go '$bootgo'.' >[1=2] 86 exit bootstrap 87 } 88 89 # Get the exact bootstrap toolchain version to help with debugging. 90 # We clear GOOS and GOARCH to avoid an ominous but harmless warning if 91 # the bootstrap doesn't support them. 92 GOROOT_BOOTSTRAP_VERSION=`{nogoenv $GOROOT_BOOTSTRAP/bin/go version | sed 's/go version //'} 93 echo 'Building Go cmd/dist using '$GOROOT_BOOTSTRAP'.
