On another windows machine, creating the frame buffer object works (no more GL_FRAMEBUFFER_UNSUPPORTED error). But the rendering looks strange, this is not how it is supposed to look, right?

Help with metacello configuration needed

by Gabriel Cotelli

Hi guys, I need some help with a metacello configuration. The development version is working OK, but I can't find a way to define a "version" that works. The configuration implies some conditional loading logic and optional groups. Here's the case and how to reproduce it: - Take a 3.0 Pharo image - Add the repository http://smalltalkhub.com/mc/gcotelli/RenoirSt/main and load ConfigurationOfRenoirSt-GabrielOmarCotelli.11. - Open a workspace and print the result of: *(ConfigurationOfRenoirSt project version: '1.1.0') record loadDirective. * *"* *linear load : * * linear load : 1.1.0 [ConfigurationOfRenoirSt]* * load : RenoirSt-GabrielOmarCotelli.28* * load : RenoirSt-HTML-GabrielOmarCotelli.3* * load : RenoirSt-HTML-Tests-GabrielOmarCotelli.4* * load : RenoirSt-Tests-GabrielOmarCotelli.22."* That's the first branch of the conditional loading. Now go to the ConfigurationBrowser and install the stable version of Units package. and retry the previous code, the result now is: *linear load : * * linear load : 1.1.0 [ConfigurationOfRenoirSt]* * load : RenoirSt-GabrielOmarCotelli.28* * load : RenoirSt-HTML-GabrielOmarCotelli.3* * load : RenoirSt-HTML-Tests-GabrielOmarCotelli.4* * load : RenoirSt-Tests-GabrielOmarCotelli.22* * load : RenoirSt-UnitsCompatibility-GabrielOmarCotelli.1* * load : RenoirSt-Seaside-GabrielOmarCotelli.1* * load : RenoirSt-Seaside-Tests-GabrielOmarCotelli.1* when I expect it to be *linear load : * * linear load : 1.1.0 [ConfigurationOfRenoirSt]* * load : RenoirSt-GabrielOmarCotelli.28* * load : RenoirSt-HTML-GabrielOmarCotelli.3* * load : RenoirSt-HTML-Tests-GabrielOmarCotelli.4* * load : RenoirSt-Tests-GabrielOmarCotelli.22* * load : RenoirSt-UnitsCompatibility-GabrielOmarCotelli.1* I don't get why in the second case metacello is trying to load the Seaside related packages when this packages are in a group that should not be loaded by default. *And if I use #development instead of the version name the result is the expected one (actually the versions are the same for development).* Any help is appreciated.

Re: [Pharo-dev] Pharo as a NT service

by Esteban A. Maringolo

To implement a 100% native service the executable must support certain "functions". Which I don't think Pharo VM does. However you could use srvany.exe to run any executable file as a service (http://support.microsoft.com/kb/137890) Regards! Esteban A.

Pharo as a NT service

by phil＠highoctane.be

I need to be able to run a Pharo VM+image as a service. I saw that in the Windows VM there are such flags. But I do not know how to make that work (or if it still works). Anyone knowing? Phil

This error is going from OpenGL itself. GL_FRAMEBUFFER_UNSUPPORTED is a constant reported by opengl.. are you going to introduce separate error-handling method for each and every possible error code which opengl produces (includes hundreds of extensions and more coming each year) ? If yes, then i wish you good luck! :) The complete error description can be found in corresponding OpenGL documentation. As well as recommendations what to do and what not.
