Re: Segmentation fault at exit of gui

Post by mlundh »

I just got my CF2, its a beauty! Running on my mac everything works fine and it is a lot of fun to fly!

Running my ubuntu machine I also had the joystick module problem with the latest version of cfclient. I added the joystick module to the installation folder manually and that solved my problem. I agree that that setup.sh and setup.py should be updated.

I have another input related problem though, the throttle mapping has stopped working. Everything works fine in the input device configuration window, all axis work the way they should, but after save and switch to main window the throttle stops working. I have double checked the device and mapping. Any idea?

Maybe this helps? It's just a guess though, I didn't really try to understand the code.

Glad to hear that you like it! Both of these has been fixed in the latest version on master so try to pull it.

I have this problem too. I'm running OSX Yossemite on my 2014 MacBook Air.

I've been using the VM and it works fine, but then I got it working directly. Here are the logs. It crashed a few times and I want to see what's up.

What steps did you use to install necessary dependencies on your Mac? Are you using MacPorts, Brew or native python libraries?
