jakelinux: When I try to run Trine: Enchanted Edition on Kubuntu 19.04 I get this error:

./bin/trine1_linux_launcher_32bit: /home/jake/GOG Games/Trine Enchanted Edition/lib/libz.so.1: version `ZLIB_1.2.9' not found (required by /lib/i386-linux-gnu/libpng16.so.16)

So Trine is bundled with an old version of zlib that won't play nice with the libpng from my package manager, and as a result the game won't run. I had this problem on 18.10 and (I think) 18.04 too. Is there any chance that the developers will update the GOG version to actually be playable out of the box on modern Linux?

adamhm: It looks like GOG bundled some libraries that are now causing some problems for more recent distros. Try removing everything from <installdir>/lib/ except for libpng12.so.0 and libpng12.so.0.50 - this got it starting for me on Linux Mint 19.2 (which is based on Ubuntu 18.04).

cgr37712: this no longer works for newer linux mint distros like linux mint 21.1 any suggestions

melioratio: Have you tried using symlinks (shortcuts) to "fool" the game into thinking it's using the required libraries when it's actually using the ones on your system which are probably newer? I've done this with a few games and it worked (though I'm on an Arch based system and SUSE based in the past).
