GLFW_jll : Segfault on finding XOpenDisplay

[willcoxe]

Hi all,

Briefly, I fist opened this issue here on discourse to which I received no responses so I opened another issue in the GLFW github and they referred me here, suggesting this was a BinaryBuilder issue.

TLDR; The issue is one of GLFW.Window() segfaulting, irrespective of

1. julia version or julia installed with
   a) juliaup
   b) git clone & make
   c) snap
2. GLFW version
3. julia> dllist() finding libX11
4. using a single monitor or two
5. C example code for opening a window compiling and running properly
6. glxinfo -B showing no issues

OS: Ubuntu 24.04.3 LTS

Some glxinfo:

~> glxinfo | grep -i OpenGl
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: AMD Radeon Graphics
OpenGL core profile version string: 4.6.0 Core Profile Context 25.10.250708
OpenGL core profile shading language version string: 4.60
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:

OpenGL shading language version string: 4.60

Some info from vulkaninfo:

========
GPU0:
	apiVersion         = 1.4.308
	driverVersion      = 2.0.342
	vendorID           = 0x1002
	deviceID           = 0x1681
	deviceType         = PHYSICAL_DEVICE_TYPE_INTEGRATED_GPU
	deviceName         = AMD Radeon Graphics
	driverID           = DRIVER_ID_AMD_PROPRIETARY
	driverName         = AMD proprietary driver
	driverInfo         = (AMD proprietary shader compiler)
	conformanceVersion = 1.4.0.0

Segfault in julia:

julia> GLFW.Window()
lib for symbol XOpenDisplay is missing

[401894] signal 11 (1): Segmentation fault
in expression starting at REPL[2]:1
unknown function (ip: (nil)) at (unknown file)
Allocations: 3086097 (Pool: 3084732; Big: 1365); GC: 5

There is some additional information in the discourse and the GLFW issue.
Any idea what the problem might be?

Thanks in advance!

It's not helpful for package developers to claim a segfault is BinaryBuilder's fault without any effort to find the root cause: JuliaGL/GLFW.jl#245 (comment). I'm going to close this ticket until someone brings an evidence there's actually something problematic here.
