setRotation issue. (CEGUI 0.7.1)

[Bababoo]

Hi, im having issues using CEGUI::Window::setRotation(const Vector3& rotation) with the OpenGL renderer.
CEGUI Version: 0.7.1
This is the troublesome code:

Code: Select all

CEGUI::Vector3 rotation;
CEGUI::Window* window;

window = CEGUI::WindowManager::getSingleton().getWindow("TestWindow");
rotation = window->getRotation();
rotation.d_z+=10;
window->setRotation(rotation);

Ive tried on several PC's these are the results:

First PC OS: Ubuntu 9.10
Video board manufacturer: Nvidia
Calling setRotation crashes the application, it crashes on allocateRenderingWindow()

Code: Select all

    if (!d_autoRenderingWindow)
    {
        d_autoRenderingWindow = true;

        TextureTarget* const t =
            System::getSingleton().getRenderer()->createTextureTarget();  //*** Crashes here ***

Log:
30/03/2010 12:07:34 (Std) Window::setRotation - Activating AutoRenderingSurface on Window 'TestWindow' to enable rotation support.

Second PC OS: Ubuntu 9.10
Video board manufacturer: Nvidia
Calling setRotation crashes the application, it crashes on allocateRenderingWindow()

Code: Select all

    if (!d_autoRenderingWindow)
    {
        d_autoRenderingWindow = true;

        TextureTarget* const t =
            System::getSingleton().getRenderer()->createTextureTarget();  //*** Crashes here ***

Log:
30/03/2010 12:20:50 (Std) Window::setRotation - Activating AutoRenderingSurface on Window 'TestWindow' to enable rotation support.

Third PC OS: Ubuntu 9.10
Video board manufacturer: ATI
TestWindow texture dissapears (So the window gets all white) but rotates fine.

Log:
30/03/2010 12:38:17 (Std) Window::setRotation - Activating AutoRenderingSurface on Window 'TestWindow' to enable rotation support.

Fourth PC OS: Fedora 12
Video board manufacturer: Nvidia
Calling setRotation crashes the application, it crashes on allocateRenderingWindow()

Code: Select all

    if (!d_autoRenderingWindow)
    {
        d_autoRenderingWindow = true;

        TextureTarget* const t =
            System::getSingleton().getRenderer()->createTextureTarget();  //*** Crashes here ***

Log:
30/03/2010 12:40:12 (Std) Window::setRotation - Activating AutoRenderingSurface on Window 'TestWindow' to enable rotation support.

Fifth PC OS: Fedora 10
Video board manufacturer: Chipstet Intel. (Its an embedded PC)
Works perfectly.
Log:
30/03/2010 12:58:23 (Std) Window::setRotation - Activating AutoRenderingSurface on Window 'TestWindow' to enable rotation support.

Sorry if there isn't enough information.
Also: Thanks for your hard work guys. CEGUI is great.

Hi, sorry to hear about the troubles

For one of the NVidia equipped machines that the app crashes on, please post:
1) The indicated section from the CEGUI.log file
2) The type of "crash" - such as segfault or whatever.
3) A backtrace from the point of the crash.

For the ATI machine with the 'white' window, please post:
1) The indicated section from the CEGUI.log file.

Thanks!

CE.

Thanks for the fast response.
I hope thats the info you asked for.

For the ATI white surface it's bound to be related to FBO completeness checks (or the lack of them, I should say). I will try and investigate further, though it's difficult when/if I can't reproduce the issues.

The backtrace you posted is kind of what I was after, but actually lacks any useful information. I'm not sure how you got that, but for example if I set a breakpoint at the top of that function (since it doesn't crash for me - also on NV hardware ), and request a backtrace, I get this:

Code: Select all

(gdb) bt

which as you can see, contains a lot more useful info, such as files, line numbers and argument values (some, or all, of which may not be available if the binaries are stripped). If you can get the extra info, that would be great - especially since I can't reproduce this issue here.

Sorry my mistake. GDB tells me this:

Again sorry and many many thanks for your help.

Hmmm. Really annoying that it happens to be dying in the GL call. Not entirely sure what that could be, unless the ptr we pass in to receive the integer is somehow messed up. I don't have any real ideas at the moment as to what that could be - especially given that the call works elsewhere.

Thanks for the help.

Cheers.
