[Linux] Shadwen fails to launch because of no libpng12.so.0

[shmerl]

I bought GOG version, and now I'm getting this:

Code: Select all

Running Shadwen
./bin/shadwen_linux_launcher_64bit: error while loading shared libraries: libpng12.so.0: cannot open shared object file: No such file or directory


libpng 1.2 is already deprecated and doesn't exist in Debian. Can you use libpng 1.6 instead?

Same bug plagues Trine 3 by the way.

Running it directly avoids the problem (since only the launcher depends on the invalid library):

Code: Select all

LD_LIBRARY_PATH=/opt/games/shadwen/game/lib/lib64 bin/shadwen_linux_64bit

But result was hanging with the mouse cursor wasn't moving and it didn't even react to keyboard, so I had to kill the process from the tty (Ctrl+Alt+F1) which still worked. I'll do some more tests, but so far the game is unplayable.

OK, the hanging happened apparently because without running the launcher, game wasn't properly configured. I managed to start the launcher by copying libpng12 from Debian Jessie into the game's lib/lib64 directory.

To developers: can you please either ship libpng12 with the game, or even better, switch to up to date library?

Hi shmerl!

I think the dependency is indirect one via WXWidgets, which would explain it being required only by the launcher (haven't checked tho, but would make sense).

We'll take a look if the dependency could be dropped or bundled with the game, but currently I do not know about our patching schedule so it could take some time.
