Well, that worked. I suppose these edits will be in the next unstable version, right?

Regardless, thank you so very much for your help. Bless you. 🙏

Change the declaration on line 735 from 
static char no_patch[] = to
static unsigned char no_patch[] =  

A quick file content search tells me it's in the following files...
fontform.cxx
jswtitle.cxx
screenedit.cxx
screenshot.cxx
spriteform.cxx

That's apparently caused by the version of libpng in use. I think it should be possible to replace
png_ptr->jmpbuf with 
png_jmpbuf(png_ptr) and see if that helps. You may have to do it in several files.

Thanks for the tips, but I did not know I needed the SDL1.x compatibility libraries. I'll check it out on my MX Linux laptop later. MX Linux is based on Debian Stable btw.

Well, Linux is my main operating system and the one I wrote JSWED on, so it ought to be possible to build it (I use Ubuntu 24.04.4 LTS). So I'd:
Install the SDL 1.x compatibility libraries. In Ubuntu these are the libsdl1.2 and libsdl1.2-dev packages. I think libsdl-image1.2 and libsdl-image1.2-dev may be required as well. Install libxml (packages: libxml2 and libxml2-dev) Downloading the source code for JSWED from the link @jetsetdanny gave. Unpack the archive into a directory. Open a terminal window. Use cd to change to the directory where you unpacked jswed, and type ./configure && make && sudo make install If it built and installed without errors, then typing jswed at a command prompt will launch it. 

Hi. My name is Chelsea but you can call me Cheez. What brought me here is @UncleWan's PvZ JSW48 remake and I am curious about how to make kinda games.
If you got any pointers on how to use JSWED on Linux (probably with Wine I would guess), I would appreciate it. Other than that, I hope to be friends with y'all. ❤️

Slightly late but Welcome @Cheez26

Not too much more to do. I have npcs. miner and misc graphics in sprite sheets, the music is in opus format and the text will be done in custom fonts rather than a bitmap. Screen record works, save state works and the html level/npc editor is about 90% done but working.

I have a very busy work week. But hopefully later this week or early next week at the latest. Would be great to have some feedback from testing etc

latest editor screenshot

I sure hope so because I had a one heck of a time trying to compile JSWED for MX Linux and I just hopped back to Mint recently. @UncleWan

Here are some screenshots from my attempt to make a Manic Miner Construction Kit.

Most sprites and NPCs are now png spritesheets 32 x 32 so more detail available. These sprite sheets are made with gimp so are easily to editable. If anyone likes doing pixel art. Please do volunteer to help :)

The editor is currently a html web editor. But an in app sdl2 might also be possible. I will try and get a public repo and release up in the next couple of weeks.

Hello and welcome，Cheez！🙂
I'm really glad to know that you became interested in making JSW games because of my game.
I don't use the Linux system, so I'm sorry I can't help you with this matter.Let's see what others have to say.🙂
