OS: Sonoma 14.2.1 (23C71),
I am porting a linux code (that uses C++, QT) to mac OS. after compiling the code on mac, I get segmentation error due to libGL.dylib.
My question is how to avoid the segmentation error.
debug messages when I run it using lldb:

The error occurs when initializing an opengl window:
void MyGLCanvas::initializeGL()
{
m_width = this->frameGeometry().width();
m_height = this->frameGeometry().height();
m_initialized = true;
m_Eye[0] = 0.0f; m_Eye[1] = 0.0f; m_Eye[2] = -2.0f; //Actual code
m_PerspectiveAngleDegrees = 45.0f;
m_NearPlane = 0.01f;
m_FarPlaneOffset = 100.0f;
glViewport(0, 0, (GLint)m_width, (GLint)m_height);
Before calling MyGLcanvas::initializeGL() there is a call to setFocus() function. SetFocus is a function used in GUI programming to give focus to a specific window or control within a window.
My second question : Is setFocus valid is mac OS or is there an equivalent?
