Keep in mind if you want to port this to other architectures, LaGUI (which is the basis of OurPaint) is designed for little-endian and 64bit systems. Big-endian systems will not work, 32 bit systems might work but not verified, and files saved with 32bit LaGUI (even if it works) are probably not readable in 64 bit systems. It's a rather simple backend without much care in cross-architecture portability.

Thanks, I'll update meta.platforms. Is it also supposed to be linux only?

[ChengduLittleA]

@fgaz I developed the backend on windows but now I don't have a windows machine, so I didn't port most of the functionalities back. If I were to do so it should run on windows as well. So for now just linux.

What's the status of this?

[fgaz]

Looks like it fell off my radar...

I'll try to update to the recently released 0.2a, thanks for the ping.
