The system uses up-to-date packages for all of the zsnes dependencies.

Thanks for reporting.

I believe the current zsnes package only supports X11. `gdb zsnes` and `r` shows a SIGSEGV:
"0xf76a33f0 in _XSend () from /usr/lib32/libX11.so.6"

I can reproduce the issue in Sway/Wayland.

Could you please try running Zsnes in ie. Xfce4 and see if the problem persists?
Comment by Melissa Loos (Kaiyazeera) - Monday, 28 June 2021, 09:31 GMT
The problem occurred in Cinnamon. I do not have xfce, but someone else might report for this.
As a workaround, I switched to mednafen ;-/

I can reproduce the issue in Xfce4 as well. This is an issue on both X and Wayland.
Comment by Alexander F. Rødseth (xyproto) - Monday, 28 June 2021, 10:17 GMT
After adding -std=c++14 to make the package build again, I get the same segfault, on both X and Wayland.
Comment by Alexander F. Rødseth (xyproto) - Monday, 28 June 2021, 10:18 GMT
Also, _XSend is not in the Zsnes source code, so this might be a library issue.
Comment by Alexander F. Rødseth (xyproto) - Monday, 28 June 2021, 10:23 GMT
There are many SNES-emulators that does not depend on lib32-*.
The last release of Zsnes was 14 years and 5 months ago.

Zsnes might possibly be ready for AUR.

Gentoo bugreports hints that a segfault might also happen if lib32-zlib is compiled with -O3, but I tried recompiling that package with -O2 and got the same result.

This might be audio-related, since `zsnes -m file.smc` (launch without GUI) also segfaults.

I'm planning to patch ZSnes so that it uses SDL2 instead of SDL1.
Comment by Melissa Loos (Kaiyazeera) - Wednesday, 07 July 2021, 09:44 GMT
thank you very much!
Comment by Alexander F. Rødseth (xyproto) - Thursday, 08 July 2021, 19:31 GMT
I created a fork of Zsnes where all the patches and trickery needed to build it are committed to the repository.

Zsnes has not had a release for >14 years, so any fork that accepts pull requests is an improvement, if we are to keep zsnes in [community], IMO.

I updated the package in [community] to use this fork.
