Primitive Failed error trying openInExternalWindow

Hello Eduardo

this method is not done to be invoked like that. In the future Pharo
will move to SDL (in fact to OSWindow based on SDL or other
framework). Right now OSWindow is not ready to be really used.
Right now what you should do is resize the main window the the size of
your largest morph.
We should definitively invest more in the deployment of Application.

Hi Eduardo,

Your FFIStructures are not initialised (I thought this was solved in latest Pharo 7 ? Maybe not integrated yet). Run:

FFIExternalStructure allSubclassesDo: #rebuildFieldAccessors.

Then your code should work.

I wrote a simple game using Pharo/SDL2/Cairo and it works very well (50fps without problems, responsiveness is really good, etc.), the ReadMe includes how to run it on Ubuntu/Mac OS X/Windows, check here:

Let me know if you have other questions.

Hi, greetings!

I was trying out some examples from the Pharo By Example book on the latest development version of Pharo, and I wanted to create a stand-alone window for a simple game on Ubuntu. So I found out the openInExternalWindow method, the window appears but I get this error that I couldn't understand, and could not find any reference to it online. So I'm not sure if it's a bug.

The simplest way I found to reproduce it was:

'Hello' asMorph openInExternalWindow.

I'm using Pharo 7 on Ubuntu 17.10.

A copy of the stack:

[ self eventLoopProcessWithoutPlugin ] in OSSDL2Driver>>setupEventLoop in Block: [ self eventLoopProcessWithoutPlugin ]
[ self value.

But it seems incomplete. Any more information I can provide?

Thank you.
