Re: [Help-gsl] How To Reduce Size of GNU Included Routines

[Kees Zeelenberg]

The linker automatically links only the modules that are actually needed in 
the executable. So in this respect the executable is always of the smallest 
size possible. You might be able to reduce its size further by stripping the 
executable from its debug symbols etc. by using the Wl,-s option at the 
linking stage.
