Hi Christophe, Pere, The solution to the problem is effectively along the lines of what you indicate, except that it has to run on all our supported platforms. We have now a working solution tested on all platforms and we expect to release this facility in a coming release. The idea is to generate automatically a libXXX.map file for each libXXX.so file. Interactively, ROOT will scan the LD_LIBRARY_PATH to search for all possible *.map files to locate a given class. This new facility will simplify several operations. -we will be able to do a dynamic linking automatically when referencing an unknown class (no need for gSystem->Load anymore). -The documentation generation system will also be able to exploit this new facility to generate the class index per library. -and last, but not least, you will be able to ask "In which lib class yyy is?"
