Hi Joseph, >how to search and get relevant documentation for using certain functions Stroustrup's C++ Programming Language (3rd ed or Special ed). Cline, Lomow, Girou's C++ FAQs (2nd ed). >I'm unclear as to when I would need to use the L option to specify libraries on the command line. The -L option is used to specify the path which libraries are located. For instance, if you had some libraries at ~jolic/3party/hotdog you could specify -L~jolic/3party/hotdog and GCC would use that path location to resolve the -lhotdog library. Without the -L~jolic/3party/hotdog, GCC wouldn't know to check in that location for libhotdog.so or libhotdog.a. >Do you know of any tutorials on the internet that would cover these kinds of fundamentals. <http://gcc.gnu.org/onlinedocs/> HTH, --Eljay
