I have no idea where to debug.

Well the linker is missing a library that the source code requires,
adding "-ldl" to the end of the g++ command should work. If it has
a common sort of configure script, try:
$ LIBS=-ldl ./configure [any other args that you've been using]

If it's a handmade Makefile, you'll just have to find where
"-lXext -lX11" is specified and add " -ldl" on the end.

Ah, well that will probably be a bit more in-depth to fix. The
only easy option might be if there's a current package for
some other Linux or BSD, the package maintainers might have
already made their own patch to get around that problem.

Otherwise you could report a bug to the software's author, or
try debugging the code yourself.

If you can turn off features with command-line arguments to
gsportx, maybe see if you can get it to avoid the bit of code
causing the seg fault.

From time to time I admire this news group/mailing list.
OP is trying to compile something that was working in Wheezy for Buster!!!
Do you know when Wheezy went out of support? Do you know how Debian changed meanwhile? I see last update of this code was 2017 and it is written for
x86.
So you have to rework a lot of the code and the autotool files to make it
work. This means if you do not understand programming, better leave it.
If you understand programming ... well you wouldn't be writing here :)

I suggest you git clone https://github.com/david-schmidt/gsport and try your luck. Chances to succeed are much higher. Note that this is x86 code and
you have to add x86 to the system. Install the required dev packages
(basically follow the README). Good luck

Do you know when Wheezy went out of support? Do you know how Debian changed meanwhile? I see last update of this code was 2017 and it is written for
x86.

Well the homepage describes build instructions for the Raspberry
Pi, and unless a program is written in assembly there's no
immediate reason to assume it won't build on ARM even if only
tested on x86 by the developer.

Actually this reminds me (especially the topic name) of my recent
attempts building XFree86 for the Pi Zero running Raspbian Buster.
That software hasn't been updated since before Raspberry Pis even
existed, and although it supposably supported building on ARM, this
turned out to be broken in the last release (or else GCC worked
_very_ differently with certain bits of code back then). After
working through a much longer string of similar problems (first
just trying to build the Makefiles), and even a similar seg fault
problem, I did get it running in the end. I've got a very long log
of all the changes I had to make - being able to compare code with
Xorg offered a good way to cheat, except where subsystems had been
completely rewritten since XFree86.

One hopes that an emulator like this would be a lot easier than
that though. XFree86 ties into a lot of lower-level stuff which is
more architecture-dependent than most other software needs to be.
Plus it's HUGE (the Makefiles still had rules for building on a 486
- I can only assume that those people are still waiting for it to
finish compiling :) ).

Only if it hasn't made assumptions about x86 structure packing,
non-aligned accesses, and a lot of other subtle architecture pitfalls.

However that may not stop it building - just working :-)

FYI - it is important when compiling for a given shared lib (in this
case, X11) to install the "-dev" packages associated with it. I forget
which ones (exactly) are needed, but if you were to install the
dependencies for building gtk I bet it would be enough [or very close].

try "apt-get build-dep libgtk2.0-dev"

it's a lot, I know, but the libs you end up getting the -dev packages
for are the ones that are a) likely to be installed, and b) probably
needed for most X11 applications

NOTE: I tested this - "apt-get build-dep libgtk2.0-dev"

I think it includes all of the most popular libs for -dev packages. The default RPi includes gtk2 and the dev package needs "all that" to build.
It was around 600Mb when I just tested it on a different Linux system
(based on Debian Buster). RPi is usually very similar. But I think i
already installed all of the -dev packages on my RPi systems...

Make sure you have 'build-essential' too. You won't get far without it!
