Has anybodody managed to make a Go-Tcl/Tk binding work under Mac OS X ?

[Serge Hulne]

Event with the latest versions of:

- Xcode.

- "port" (port of the Linux tools for Mac)

-  Go.

I cannot get the libraries using a binding between Go and Tcl/Tk (such a /github.com/nsf/gothic ) to work correctly on a Mac.

The library compiles, but the executable runs only once and only after a reboot of the computer, but not twice :

If I attempt to restart an application based on that library the Tcl/Tk part just "hangs" and displays a blank area, the size of the expected Tk window.


Since "port" is basically simply a port of the Linux tool chain to Darwin, I would expect it to work in just the same way under Linux and Mac.

I have no idea why it does not work correctly.

Has anybody a suggestion on how to make this work ?

Thanks,
Serge.

I can't comment on the ports install, but homebrew works for me after giving the correct CGO flags to tell clang where to find the tcl-tk installation.

> brew install tcl-tk

> cd $GOPATH/src/github.com/nsf/gothic

> CGO_FLAGS='-I/usr/local/opt/tcl-tk/include' CGO_LDFLAGS='-L/usr/local/opt/tcl-tk/lib' go build

Something similar will probably work for ports.

Thank you very much, Chris.

I tried with "homebrew" (with the corresponding modified versions of the include path and the library path), but I obtained the same result as with the MacPorts version:

- The library ("gothic") compiles without any error messages and the test provided with it works.

However, when the examples are compiled, the resulting executables sometimes start normally, sometimes just yield a blank window instead of the expected interface.

Nevertheless, thank you very much !

I give up,  I will write the interface for my Go application with JQuery and make it communicate with the executable (the server) with Ajax.

So basically, I will swap Tcl/Tk + gothic for JQuery + Ajax.

Serge.

I didn't consider the examples as test cases and assumed that there were just some issues somewhere between the library and the examples. I did notice the same behavior. You might check out Gustavo's go-qml library if you're dead set on having a GUI application. The limetext folks have their text editor running via go-qml and it seems to work very well under OS X considering that it's development code.

Thank you very much !

I was not aware of this qml binding for Go.

Hi I have, in the meantime installed :

- Yosemite (Mac OS X 10.10.1)
- The latest version of "Port" (https://www.macports.org/)
- XQuartz 2.7.7 and now it works

Nsf.s gothic (tcl/tk to Golang binding) library appers to work correctly on Mac now !

So the assumption that the problem was linked to the (late) implementation of  X11.app was correct !
