In that case you need to create a second alias of the symbol with hidden visibility for internal use within the library. The Drepper paper explains how to do this in section 2.2.7. The problem with doing this in C++ code is that the alias declaration needs the assembler name of the function which includes the mangling, and there's no way to automatically generate that short of compiling a testcase and looking at the assembly output. You could arrange for this to be done automatically with some kind of multi-pass compilation scheme with tons of macro magic: first run g++ -S over the source, then use a perl/awk/whatever script to extract the mangled names of exported functions and substitute them back into a second compilation of the same file with the alias declarations added. To me that sounds like a fragile and complicated way of achieving a modest optimization. The wrapper function approach mentioned in that same section is probably the best way to go in the face of C++. Brian
