[SOLVED] Problems compiling opengl SDK examples in Mac OS for MeeGo target

deion · wrote on 4 Oct 2011, 12:02

Hi all,

I want to compile the opengl examples that come with the Qt SDK for MeeGo Harmattan. I am running QtCreator 2.3.0 (I do not know the version of my Qt SDK, I know it was written in the installer filename I downloaded to install the Qt SDK; how do I find out this version, other than writing it down on a napkin when downloading the installer file?). Anyway I am running under Mac OS X.
So I copied the whole /Developer/Examples/Qt/opengl directory into my work directory. From here I try to individually compile the following subdirectories/projects:

2dpainting - this compiled fine for both Desktop and MeeGo targets
framebufferobject & grabber: these compiled fine only for Desktop target; for MeeGo I am getting opengl compilation errors, see below (I haven't tried compiling projects other than these 3):

Can someone help me?

I updated to Qt Creator 2.3.1 ( I do not know the new version of Qt SDK :D )
I still have the same errors as before...
I also tried compiling another simple OpenGL example from here:
http://www.thasler.org/blog/?p=10
and below are the compilation errors for MeeGo target (again it compiles fine for Desktop target):

I will try to compile these sample projects on Windows too for target MeeGo and report the results.

Seriously !! No-one can help ?!
I mean I am trying to run OpenGL basic examples that come with the SDK, I have not modified in any way these examples. If I can't compile basic examples ... How can Nokia release an SDK before making sure their own examples at least compile.

Anyway, I'll google it more for some help.

Seriously? You bump a topic after less than 20 hours. Please be more patient! Everyone here is doing this in his/her spare time, no one is paid for the aid he/she gives. It's acceptable to bump a topic after waiting a few days, not hours.

For the time being, something to "read":http://www.catb.org/~esr/faqs/smart-questions.html.

Seriously, in 20 hours a new iPhone was released, but in the meantime I can read the forum documentation :D

I was just eager to try out some OpenGL examples and start experimenting. Now it's VERY frustrating when you can not even compile the examples that came with the SDK. I had the same experience when first trying to learn about QML. I was on Windows and I tried running any QML examples from the SDK: they wouldn't compile/package for Harmattan, and others had the same problems on forums.
Luckily I could run them on Mac OS. Looking back I am happy I could pass over those problems fast by switching to Mac, because QML proved to be such a JOY, but I wouldn't have discovered this if I was stuck in trying to get the examples compiled.

Thanks & regards,
Ionut

I'm having exactly the same problem.
Have you found any solution?

Hi deion,
Qt for Meego target use OpenGLES 2.0 as default. So you can't compile & run an OpenGL example. Try looking for the gles example in Qt SDK.

Hi all,

Looks like the opengl examples that come with the SDK were not meant for MeeGo. For complete and very WOW (see the water demo) opengl examples that compile and run fine on N950 see this:
