In short, just don't. The system programs have been tested, developed and debugged with the *SYSTEM* version of the libraries. Blindly replacing these libraries with others is something you should do only with extreme care. > what has to be set/changed, to have this setting as soon as the OS > starts?

All the compilers that I have to use for every day work and for my own stuff have options that can hardcode a 'runtime library path' in the ELF binary. What did you try to compile? What do you mean by writing ``the compilation does not even find the new libraries''? > please don't tell me things about RTFM or weblinks This is also a good way of learning new stuff though :) > i just need ~3 simple lines of what the hell to do that i get a > persisting setting for compilations and runtimes How do you know it is ``3 simple lines''?
