Hi,
I'm trying to run opensg in linux. My problem is in the initialization
of the OSG::PassiveWindow, I think.
I get the Display* and the Window from another library (Currently QT is
taking care of them), und have to create my own GLXContext.
XVisualInfo *vi, visInfo;
XWindowAttributes winAttr;
XGetWindowAttributes(mMainWidget->getDeviceContext(),
mMainWidget->getWindowHandle(), &winAttr);
// get the existing glWidget's visual-id
memset(&visInfo, 0, sizeof(XVisualInfo));
visInfo.visualid = XVisualIDFromVisual(winAttr.visual);
// get a visual for the glx context
int nvis;
vi = XGetVisualInfo(mMainWidget->getDeviceContext(), VisualIDMask,
&visInfo, &nvis);
// is the visual GL-capable ?
int useGL;
glXGetConfig(mMainWidget->getDeviceContext(),
vi,
GLX_USE_GL,
&useGL );
if (!useGL)
{
std::wcout << L"Visual is not OpenGL-capable!" << std::endl;
}
int dummy;
if( ! glXQueryExtension( mMainWidget->getDeviceContext(), &dummy,
&dummy ) )
{
std::wcout << "Error: X server has no OpenGL GLX extension" <<
std::endl;
}
// create the new context
mContext = glXCreateContext(mMainWidget->getDeviceContext(), vi,
NULL, GL_TRUE);
if(!mContext)
{
std::wcout << L"ERROR: Invalid GL context!" << std::endl;
}
if(!glXMakeCurrent(mMainWidget->getDeviceContext(),
mMainWidget->getWindowHandle(), mContext))
{
std::wcout << L"Couldn't make mContext current" << std::endl;
}
This part of code works fine (None of the error messages is printed),
and it even works using another scenegraph drawing into the current
GLContext.
But when I call OSG::PassiveWindow, I get the following warnings (they
ssem to be the key to the problem).

Then I see the rendered Window (I use a different bgcolor), and
everything seems ok. (At this time, the scenegraph is empty).
Now I load some geometry into it, and get a crash. Using the debugger I
get down to
OSGGeoPumpFactory.cpp , line 877.
But I think this line shouln't be reached.
Shouldn't line 871 fail, because in the warnings above I found: Couldn't
get function 'glLockArraysEXT'.
Does anyone have a clue what to do?
Thx,
Marco
