Segfault trying to open any stl

[Nandru86]

Hi!

I'm on Kubuntu 25.04, fstl installed from repositories (version 0.10.0-2build3), running from terminal I get:

andres@T-072:~/Descargas$ fstl lego_test_piece.stl 
QWaylandGLContext: failed to create EGLContext, error=3009
QWaylandGLContext: failed to create EGLContext, error=3009
QOpenGLWidget: Failed to create context
QWaylandGLContext: failed to create EGLContext, error=3009
QOpenGLWidget: Failed to create context
Violación de segmento ('core' generado)

on dmesg I get:

[  874.010084] fstl[5609]: segfault at 8 ip 00007748ea98fb34 sp 00007ffd127a3ef8 error 4 in libQt5Gui.so.5.15.15[18fb34,7748ea8dc000+52d000] likely on CPU 2 (core 2, socket 0)

and attached goes what I assume is the coredump that it generated

Could you provide the OpenGL version information for your system too?

Something like glxinfo | grep version.

[Nandru86]

Sure!

andres@T-072:~$ glxinfo | grep version
server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
    Max core profile version: 4.6
    Max compat profile version: 4.6
    Max GLES1 profile version: 1.1
    Max GLES[23] profile version: 3.2
OpenGL core profile version string: 4.6 (Core Profile) Mesa 25.0.3-1ubuntu2
OpenGL core profile shading language version string: 4.60
OpenGL version string: 4.6 (Compatibility Profile) Mesa 25.0.3-1ubuntu2
OpenGL shading language version string: 4.60
OpenGL ES profile version string: OpenGL ES 3.2 Mesa 25.0.3-1ubuntu2
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20
    GL_EXT_shader_implicit_conversions, GL_EXT_shader_integer_mix, 

[ptsouchlos]

Sure!

    GL_EXT_shader_implicit_conversions, GL_EXT_shader_integer_mix, 

Thank you. Also just to clarify, does fstl segfault when you first open it without loading an external stl file? Do you see the isosphere in the viewer?

Yep, same error than before:

andres@T-072:~$ fstl
QWaylandGLContext: failed to create EGLContext, error=3009
QWaylandGLContext: failed to create EGLContext, error=3009
QOpenGLWidget: Failed to create context
QWaylandGLContext: failed to create EGLContext, error=3009
QOpenGLWidget: Failed to create context

Thanks - I suspect this is wayland specific. It will be tricky to reproduce but it could be something as simple as forcing software rendering or installing a possibly missing driver

Oks! I have an older ubuntu 24.04 running X11 on the office, will try to install it there and test El mar, 27 may 2025, 12:15, Paul T ***@***.***> escribió:
