Best way of compiling applications to run on older linux distros
Tue Nov 4 17:25:00 GMT 2008
I've never tried it on too old platforms, but isn't it sufficient to copy ALL new libraries with which your application is dynamically linked from the new machine to the old one, and then adjust LD_LIBRARY_PATH in order to guarantee that the correct libraries are used (check with "ldd application_name")? OK, that may raise juridical questions, if your application is not GPL'ed (may be, I have no idea...) and increases the total size of the project. But I think, that should work? What am I missing?
PS: I have the impression, that's the technique used by most windows applications: simply install all needed libraries in the adequate version on the target machine ...
