Why would it be impossible to fully statically link an application?

Question

I\'m trying to compile a statically linked binary with GCC and I\'m getting warning messages like:

warning: Using \'getpwnam_r\' in statically linked application         


        

Answer 1

AFAIK, it's not impossible to fully statically link an application.

The problem would be incompatibility with newer library versions which might be completely different. Say for example printf(). You can statically link it, but what if in a future that printf() implementation changes radically and this new implementation is not backward-compatible? Your appliction would be broken.

Please someone correct me if I'm wrong here.
