Greetings, after being able to build BRLCAD without "-DBRLCAD_BUNDLED_LIBS=ON" option, both Archer and Mged crash.
This is the output from Mged while using GDB:

Thank you for this report. Can you tell what your operating system and hardware is? Also, it would help if you ran "b exit" and "bt" so we can see the full backtrace where they are halting. At a glance, archer and mged appear to be failing for completely different reasons.
One workaround is to disable opengl (-DBRLCAD_ENABLE_OPENGL=OFF) which should make mged work, but will disable archer completely.
My apologies for my ignorance:
Operating system: Void GNU Linux
CPU: POWER9 ppc64le
GPU: AMD Vega 64
Motherboard: Talos II Lite (https://www.raptorcs.com/content/TL1MB1/intro.html)
regarding "bt" and "b exit " on mged:
regarding "bt" and "b exit " on Archer:
I can confirm I can run Mged by disabling OpenGL.
Tell me if you need more info, I will gladly provide it.
That's perfect for mged, thank you! For archer, you have to run "b exit" first, then "run", then "bt". You may need to run "b exit_" alternatively.
Ok, this is the output, you can tell that I don't know what I'm doing :P
I have to go so my next reply might be way later. I will be online as soon as I can.
thats my mistake, I meant "b _exit"...
Sorry for the delay:
You set the breakpoint correctly with "b _exit" but then needed to run "bt" to get the backtrace.
Can you see if "bwish" runs? Should just pop open a simple window.
And seems BWISH runs without issues
One detail, I see that you have not installed... on your hardware, installation may be necessary.
You are on a hardware configuration that we've not tested the GUI on ourselves before. Both the OpenGL/Mesa issue affecting MGED and the hv3/tk8.6 issue affecting Archer appear to be likely related. Since you have a solution for MGED (i.e., X11-only), it may be best to focus on what's going wrong with Archer. Have you tried compiling against a system-installed tcl/tk 8.6 instead of bundled libs?
Greetings, after realizing I didn't have tcl's dev packages installed, I proceeded in installing them and now I cannot compile it and the following error appears
If I build it with the bundled libs, another compilation error appears:
Thank you a lof for your help
Hi Draena, so this is complex because each change you make or try involves a whole chain of events that have different requirements and things to check. When you installed new system libraries, did you rebuild completely fresh? You will want to delete your build directory every time you change what's installed on your system.
The first error (default build) appears to be some incompatibility between Itk and (presumably) your system IncrTcl. What (if any) version of IncrTcl do you have installed on your system?
For the second error (bundled build), that seems to be this issue: https://gitlab.kitware.com/paraview/paraview/-/issues/18176
Greetings Sean, I made sure I deleted the build directories after doing any changes, the error messages are the same.
Regarding tcl, I have 8.6.11 installed on my system.
