I'm writing a library (or collection of libraries really) that has a "front end" interface library and several "back end" implementation libraries. The front end basically has a single point of entry: a factory method that accepts a string that identifies a particular back end. The back end library is then dynamically loaded and used to create the appropriate environment object. Note, multiple back ends can be in use at the same time. All other objects are allocated at run-time from this environment and all other functions are accessed from the allocated objects. Sounds like a good design. I just wonder if it will really work in C++. Eric. _______________________________________________ http://lists.gnu.org/mailman/listinfo/libtool
