M1 Crash With Irrlicht + OpenGL

[Henkie]

Hi all,

I've been struggling to run reliably with Irrlicht and OpenGL on a Mac M1, does anyone face a similar issue? Sometimes it launches fine, but often I get a segfault or bus error in the following part:

m_device_params.DriverType = irr::video::EDT_OPENGL;

m_device = irr::createDeviceEx(m_device_params);

In ChVisualSystemIrrlicht.cpp

"""

void ChVisualSystemIrrlicht::Initialize() {

if (m_device)

return;

// Create Irrlicht device using current parameter values.

m_device = irr::createDeviceEx(m_device_params);

if (!m_device) {

std::cerr << "Cannot use default video driver - fall back to OpenGL" << std::endl;

m_device_params.DriverType = irr::video::EDT_OPENGL;

m_device = irr::createDeviceEx(m_device_params);

if (!m_device) {

std::cerr << "Failed to create the video driver - giving up" << std::endl;

return;

}

}

"""

Thank you in advance for any suggestions!

Forcing it to directly use OpenGL instead of trying to use the default device seems to have resolved the crash:

For those interested, change the code above as follows:

void ChVisualSystemIrrlicht::Initialize() {

if (m_device)

return;

// Create Irrlicht device using current parameter values.

m_device_params.DriverType = irr::video::EDT_OPENGL;

m_device = irr::createDeviceEx(m_device_params);

if (!m_device) {

std::cerr << "Failed to create the video driver - giving up" << std::endl;

return;

}
