Segmentation Fault Error on Compile

[ezacharyk]

I am starting my projects again from a fresh install of HaxeFlixel. My computer decided to crash and needed restored. So I just reinstalled Haxe, Lime, and HaxeFlixel.

But now my project that was compiling just fine is crashing with a Segmentation Fault.

I went ran all the commands from the Install HaxeFlixel documentation, and I am not sure what is left.

These are the libraries I have installed:

actuate: [1.8.9]
box2d: [1.2.3]
flixel-addons: [2.11.0]
flixel-demos: [2.8.1]
flixel-templates: [2.6.6]
flixel-tools: [1.5.1]
flixel-ui: [2.4.0]
flixel: [4.11.0]
hscript: [2.4.0]
hxcpp: [4.2.1]
layout: [1.2.1]
lime-samples: [7.0.0]
lime: [7.9.0]
openfl-samples: [8.7.0]
openfl: [9.1.0]
systools: [1.1.0]

Haxe is on version 4.2.4.

This is the output of lime test linux -verbose:

Like I said, this project was running just fine prior to having to reinstall my OS and the HaxeFlixel libraries. Any suggestions on what to fix?

[ezacharyk]

Alright. I think I am just dumb. The problem was my game controllers. I had unplugged them during my OS reinstall and my game project doesn't properly handle the case that they are not plugged in. That is what is going on.

Thanks for looking if you were researching.

[ezacharyk]

To further elaborate here, I only have two game controllers to test with, a Xbox 360 controller and a Logitech Rumble Pad. The 360 controller works fine out of the box, but the Logitech controller's inputs are all wrong by default on Linux. So I check for the controller model and if it is not XINPUT, I change it to XINPUT. This block of code was causing the segmentation fault if no controllers were plugged in.

So I wrapped it in a if statement that checked the number of active gamepads to make sure there were any.

if (FlxG.gamepads.numActiveGamepads > gamepadID)
		{
			controller = FlxG.gamepads.getByID(gamepadID);
			if (controller.model != XINPUT)
			{
				controller.model = XINPUT;
			}
		}
