If you need the information, > it is lost. I second that. But I'm stripping those libraries for (at least) 3 reasons:
1. Already mentioned: my app became way too big 2. I'm fully confident that libstdc++ and libc are fully mature. They've been tested already a tig times by many millions of people, so there's no need any more for me to keep the debug information into those libraries 3. I have to statically link libstdc++ into my application, because it's not part of the RFS which is flashed into the FoxBoard (mine is still the "old" MCM, being 4MB flash, 16MB RAM). It's not part of the RFS, simply because if it would be part of the RFS, the complete image (kernel + RFS) would not fit any more into that 4MB flash. > > When building statically (the way I do it), the results are really > > very positive. > > When building statically, parts of the library are copied in your > application.

Well, if I'm stripping my application *after* the linking phase, also the debug info needed to debug *my* application would be gone, isn't that so? If yes, than that's not an option for me since I want to be able to debug my app. > > Finally, my app dropped from 7645244 bytes to 1964781 bytes. > > You can still strip it, as you didn't remove extra info from your own > code (only from the library).

But again, if I do this then I'm kicking out the debug info of my own app too, am I right? > To see the real size of an application, use "size" (or "cris-size" > if you lack the binutils-multiarch package). Another one I was not aware of, so thanks again... Best rgds, --Geert
