How to Build UPBGE on Ubuntu

[nutti]

I tried to build UPBGE on Ubuntu 22.04 by following the build process. But, it got error when I execute a command make -C build.

It seems that the error message comes from the mismatch of the OpenImageIO version. UPBGE expects OpenImageIO v2.3, but only v2.2 is supported on Ubuntu 22.04.

• 2.3: https://openimageio.readthedocs.io/en/v2.3.19.0/imagebuf.html
• 2.2: https://openimageio.readthedocs.io/en/v2.2.19.0/imagebuf.html

This makes us change the installation process on Ubuntu 22.04. Could you show me the installation process on Ubuntu 22.04?

Hello, I advise you to follow blender guide instead: https://wiki.blender.org/wiki/Building_Blender/Linux/Ubuntu which is more complete and maybe more up to date. Instead of cloning blender sources, you can clone upbge sources:

git clone https://github.com/UPBGE/upbge.git

for libs, the address seems a bit different:

https://svn.blender.org/svnroot/bf-blender/trunk/lib/linux_x86_64_glibc_228

But i'm guessing it should work on an ubuntu LTS version...? I'm not sure though because I think svn has openimageio 2.4 now, but you can try anyway.

Thanks. Now, I can build UPBGE without any error by following the instruction.
