Dear Maintainer,

it appears that maxima fails to load the package draw on the loong64
architecture.

The issue can be reproduce  on the current long64 porterbox as follows.
The command

$ echo 'debugmode(true);load(draw);quit();' | maxima

gives

	Maxima 5.49.0 https://maxima.sourceforge.io
	using Lisp GNU Common Lisp (GCL) GCL 2.7.1 git tag Version_2_7_2pre35
	Distributed under the GNU Public License. See the file COPYING.
	Dedicated to the memory of William Schelter.
	The function bug_report() provides bug reporting information.
	(%i1)
	(%o1)                                true
	Unknown reloc type 110
	loadfile: failed to load /usr/share/maxima/5.49.0/share/draw/draw.lisp
	 -- an error.  Entering the Maxima debugger.
	Enter ':h' for help.

This issue does not occurs on other officially supported architectures.

I suspect that this issue is related to the gcc-16 transition,
but I cannot confirm since I am not familiar with the maxima
building process.

#4731 draw() does not work on new debian 13 installation

I get an error message when attempting to use draw() and wxdraw() inside
wxMaxima.

I get errors like "cannot load draw.lisp."

I discovered that if I install the GCC compiler on Debian that the bug went
away.

Apparently there is additional maxima code that needs to be
compiled when certain functions are called by maxima.

After a cursory look I think the problem might be lack of R_LARCH_CALL36
handling in gcl27 in h/elf64_loongarch64_reloc.h

I have added more details to

https://sourceforge.net/p/maxima/bugs/4731/

#4731 draw() does not work on new debian 13 installation.

Is this the place to discuss these issues?

I am a user of maxima and wxmaxima, and I would like these software
programs to continue running on new, clean, default debian installs.
So I am trying to figure out a way to deal with debains policy of not
installing gcc.

== bug #1143982 ==
Can we make draw() part of Maxima's pre-compiled core instead of an
optional package?
Draw() seems like a core routine to me, not an optional package like ctensor.

So do we already have or can we add a way to maxima's build system to
1) run gcl to create the c code for draw
2) compile and link this c code with gcc into the core or a shared library.

Hi,
With GCC 16.2 the default code model on loong64 is -mcmodel=medium.

You can get the old behavior (-mcmodel=normal) with:

Hi,

I attached a patch that fixes the relocation issue.
This fixes the load(draw) issue in maxima, and a FTBFS with GCC 16 in fricas.
