cybrthng asks: "How do you stop glibc hell on Linux? I thought I'd long lost the ever familiar DLL hell on Windows, but with Linux it breaks the applications so bad its not funny. Will Linux only be able to truely survive with applications available in source form? For instance take Oracle Applications, it is nearly impossible to install it on RedHat 7.0 or any glibc 2.2 based distro since the applications were built against 2.1.x. When you install this software it tries to relink itself with the correct libraries and fails miserably. You can however force it to use glibc-compat, but that isn't a solution for a production system. Do vendors have to recompile there applications for every kernel, every library and every distro? How can I use Linux when the core libraries don't seem to be forwards or backwards compatible across different distributions?"
