PlatformLinux i386OSDebianOS Versionbuster (testing)

Target VersionFixed in Version 
Summary0010771: has no dependency on in the 32 bit build
DescriptionWhen trying to start the 32 bit version of Dwarf Fortress I get an error window saying “Not found: data/art/curses_640x300.png” on the screen and the message “libpng error: bad parameters to zlib” is printed on stderr. When I dismiss the error Dwarf Fortress does not start. The 64 bit version doesn't seem to have this problem.

The cause of this problem seems to be that the 32 bit version of is missing the dependency on This can be confirmed by comparing the readelf output of as follows:

$ readelf --dynamic amd64/libs/ | grep libz
 0x0000000000000001 (NEEDED) Shared library: []

$ readelf --dynamic i386/libs/ | grep libz
<no output>

This can be worked around by setting LD_PRELOAD=/lib/i386-linux-gnu/ before starting Dwarf Fortress.
Steps To ReproduceTry to start Dwarf Fortress on a 32 bit Linux system without setting LD_PRELOAD.
Additional InformationThis issue seems to be related to 0002688. Maybe the fix described there wasn't applied to the i386 version?

I could run 32bit df 44.09 on ubuntu 16.04 normally, but after i upgraded to 18.04 the same issue came up with 44.10. I didn't try to run 44.09 after upgrade though, will check that up.

Edit: 44.09 won't run usually either.
