Well I have in principle the Ubuntu package for libpng12 installed at the right place. I didn't modify it. However, I installed he latest version libpng 1.62 whih I compiled. I have ImageMagick, wxWidgets and WxPython working with libpng1.62 Till now I didn't had any application not working with this set-up. I have a lot of Photo Video applications and the latest versions can compile with libpng1.62. However it looks like Ubuntu officials apps are locked in at libpng1.2 ... However I did try to compile libcairo ad i is still not working at all with libpng1.62 (I mean libpng >= 1.15). libpng.org on their website still have the remainder for making the code compatible. Portability Note ---------------------- The libpng 1.5.x and 1.6.x series continue the evolution of the libpng API, finally hiding the contents of the venerable and hoary png_struct and png_info data structures inside private (i.e., non-installed) header files. Instead of direct struct-access, applications should be using the various png_get_xxx() and png_set_xxx() accessor functions, which have existed for almost as long as libpng itself. If your application is fully dependent on libcairo that may explain the behaviour. Anyway I have left he libpng1.2 libraries at their original place. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1191195 Title: Cannot launch banshee: Unhandled Exception: System.DllNotFoundException: libgtk-x11-2.0.so.0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/banshee/+bug/1191195/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
