Created attachment 429456 [details, diff] Patch to the Makefile to build the missing object. Due to changes in the libgraphics.so sources, the Makefile provided no longer builds all the objects needed for running dwarf-fortress. /opt/dwarf-fortress/libs/Dwarf_Fortress: symbol lookup error: /opt/dwarf-fortress/libs/libgraphics.so: undefined symbol: _ZN7widgets7textbox6renderEiiii A patch is attached that I've used to get a working libgraphics.so built on my system.
Fixed in latest.
