Can't install on Debian Bullseye

[RagingFlames]

I'm trying to run the xlinux_install script but it isn't working. I manually found and installed all the dependencies. This is what it return when I try to install.

From looking online, the latest guide on how to install this on linux is from 5 years ago, is it possible to get a new guide?

[xaizek]

It works for me if I change LCEngine2.so to LCEngine4.so in LCEngine/xcython_linux.sh.

[RagingFlames]

Are there any plans to update the instructions or change that by default? It also still doesn't work, with a similar error.

[xaizek]

Have no idea why @lukasmonk hasn't updated that script yet.

Are you running the script while inside LCEngine/ directory? running build_ext should be followed by LCEngine4.so being build (invocations of gcc).

[lukasmonk]

Changed 2 with 4. All my efforts at the moment are focused on the new version of the program with python 3.7 and pyside2 / qt5 In the new program I would like to create a version of Linux / 64. For now I will settle for this new version to work for Windows32.

[RagingFlames]

Is there a time line for the Linux version? Is it worth just waiting, or should I keep googling these errors?

[lukasmonk]

I would like to publish the windows version after summer, and from that moment, once it stabilizes, I will try to work the Linux version. All my efforts are dedicated to this new version (LucasChessR).

[RagingFlames]

Alright, I understand. If there is nothing more that can be done at the moment to make this work on Linux you can close this issue if you want, or leave it open until its working for reference.

[xaizek]

It works on Linux. Look through scripts and files in LCEngine/ directory, maybe you'll figure it out. For example xcython_linux.sh invokes python command. Is that python2 on your system? If not, you should change that to python2.
