DES only pointed out a compilation problem (?), but my program actually
does something. When made a shared object, it writes a string of
characters to the standard output of the program which links to it or
dlopen()s it. That doesn't fit my definition of `doing nothing'.
You may as well `cin>>' data, perform any calculations required, and
`cout<<' output.
A quick hack to find out the list of files which do nothing in much the
same manner on your machine:
$ find /usr/lib/ -name "*.so*" |xargs grep _init
Still not guessed? All those libs do something at loading time.
Of course, they're not all written in C++. Some might have been written
in C --- but I doubt it's *portable* C. Or can you persuade me of the
contrary?
