Looking at the strace output, it does seem to relate to libpng: --8<---------------cut here---------------start------------->8--- open("/gnu/store/hf5kklv837xbfcv6gc7gpsj36l69j3sj-glibc-2.19/lib/libpng15.so.15", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) open("/gnu/store/6z7k9ms4sf367c3phl7djhb740ly3dqi-gcc-4.8.2/lib/libpng15.so.15", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) open("/gnu/store/hf5kklv837xbfcv6gc7gpsj36l69j3sj-glibc-2.19/lib/libpng15.so.15", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) close(6) = 0 munmap(0x7f09053e2000, 4096) = 0 --- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0x8} --- --8<---------------cut here---------------end--------------->8--- And indeed, ‘abbaye’ is not explicitly linked against libpng, so it can’t find it. If I do: --8<---------------cut here---------------start------------->8--- LD_LIBRARY_PATH=/gnu/store/naxqxdf7f6lfpy4h481h8j8hs2r44v09-libpng-1.5.17/lib /gnu/store/9gfzrsj71ph5pk2hxn7mmpsfflz0jpc7-abbaye-1.13/bin/abbaye --8<---------------cut here---------------end--------------->8--- Then it works like a charm. I suppose we need to add -lpng on the link command line? BTW, the splash screen says “freeware”; would be great if we could change that to “free software”. (Seeing this game makes me feel younger. ;-)) Thanks, Ludo’.
