There are some makefile tweaks available at http://sourceforge.net/tracker/?func=detail&aid=3409518&group_id=6152&atid=356152 and http://sourceforge.net/tracker/?func=detail&aid=3409556&group_id=6152&atid=356152. The tweaks add the static and dynamic objects to the default rule (all). They also add a leading hyphen to the CP command so it continues on library copy failure (if you build the shared object, but not the archive, make will fail before copying the SO during install). > After this I assumed that it is installed and went about trying the > samples for RSA given on the wiki..

I'm new to crypto++ and relatively new to c > ++ too. I've got to check if that (not using a variable name) is legal C++. I thought it was when the sample was written. If legal, it might be that not using a variable does something with sequence points, or GCC is optimizing too aggressively.
