GVM on Cygwin throws an error during installation about gvm

[CMCDragonkai]

Perhaps here is where the potential switch can be: https://github.com/moovweb/gvm/blob/master/scripts/install#L81

We can use what go does:

# Test for Windows.
    53  case "$(uname)" in
    54  *MINGW* | *WIN32* | *CYGWIN*)
    55      echo 'ERROR: Do not use make.bash to build on Windows.'
    56      echo 'Use make.bat instead.'
    57      echo
    58      exit 1
    59      ;;
    60  esac

Unfortunately I'm not well versed in the arts of the bash script. If someone else can help?

I just tried out using make.bat.

It gives out a permission denied error.

You need chmod it in Cygwin just prior to running it, here's a modified install script.

compile_go() {
display_message " * Compiling..."
unset GOARCH && unset GOOS && unset GOPATH && unset GOBIN && unset GOROOT &&
export GOBIN=$GO_INSTALL_ROOT/bin &&
export PATH=$GOBIN:$PATH &&
export GOROOT=$GO_INSTALL_ROOT &&
#cd $GO_INSTALL_ROOT/src && ./all.bash &> $GVM_ROOT/logs/go-$GO_NAME-compile.log ||
cd "$GO_INSTALL_ROOT/src"
chmod 777 ./make.bat
./make.bat &> "$GVM_ROOT/logs/go-$GO_NAME-compile.log" ||
(rm -rf "$GO_INSTALL_ROOT" && display_fatal "Failed to compile\nCheck the logs at $GVM_ROOT/logs/go-$GO_NAME-compile.log")
}

However after that comes some compilation errors:

# Building C bootstrap tool.

 char *goroot = GOROOT_FINAL;

Not sure where to go from here.

@CMCDragonkai your "fix" works at current version of GVM under cygwin (i'm using it with babun).

In babun. it says installs successfully. But under ".gvm\gos\go1.4\bin" go binary not found.
