Things to look for include - libpng12.so.0 is 32-bit and you need 64 (or vice versa) - libpng12.so.0 is libc5 - /usr/lib/libpng12.so does not exist - /usr/lib/libpng12.so points to something else The output you posted suggests to me the 3rd option above. ld does not use ld.so.conf: that is runtime only. ld needs .so files Cheers ...
