When you pass -static to the linker as part of the link command, it will search for libcrypto.a rather than the default (dynamic) libcrypto.so (which should be a sym-link to the current version named libcrypto.so.VERSION-NUMBER). Also remember that the application: /usr/bin/g++ which you are calling is just the "front end" of that toolchain. It calls the sub-components (pre-processor, compiler, assembler, linker, etc) as required based on the options and files it is passed. Note also when you did: g++ --help in a terminal window that the order is: g++ <options> files not: g++ files <options> Also try: info g++ in a terminal window.
