转到构建失败:runtime / mstkbar.go:151:10:debug.gcstackbarrieroff未定义

  • install

This code compiled OK using prior release of golang (1.8.3) however fails to compile after upgrading to new golang (1.9)

~/src/gopath/src/github.com/scottstensland/infosynth $ go build infosynth.go

/usr/local/go/src/runtime/mstkbar.go:227:19: too many errors

Any ideas ? Actually, this error happens for any golang version upgrade not just the versions I mentioned here.

PS Also get same errors when issuing : go get -v -t ./...

    SOLUTION : you must first delete previous golang install prior to installing new go version

    type go    # issue this to confirm where your go lives

    a typical output :

    go is /usr/local/go/bin/go  # delete /usr/local/go not just /usr/local/go/bin/go

    so just remove it

    sudo rm -rf /usr/local/go  #  OP's missing step else above errors

    before you install new version

    export golang_ver=$(curl https://golang.org/VERSION?m=text 2> /dev/null)
    wget https://storage.googleapis.com/golang/${golang_ver}.linux-amd64.tar.gz
    sudo tar -C /usr/local -xzf ${golang_ver}.linux-amd64.tar.gz

    I use Windows10. I have to uninstall go18 with Control Panel (do not trust 1.9 installer when he asks to uninstall prev version - do it by hands). After that I remove c:\go - the default goroot and only after this - install 1.9. In my case it was 1.9.2 And of course check your GOROOT && GOPATH
