Yes, in principle. If you have code that depends on the environment it must be recompiled if you change the environment. This applies to any code, not just Geant4. It is a typical situation for visualisation because the distributer cannot know what window system and what graphics libraries are available.

However, you can short cut the rebuilding process if you know which part of the code is affected. In the case of Geant4 it is interfaces, visualisation and the user application code. For more guidance follow the link to "Appendix - Step-by-Step Installation Guides" in Chapter 2 of the installation guide.

./Configure -E -build (the -E prevents it starting to build - see ./Configure -help) ./Configure (writes environment scripts, env.sh and env.csh) source env.sh (or source env.csh if you are using a C-like shell) (cd source/interfaces; make clean; make) (cd source/visualization; make clean; make) cd <your user application working directory or examples directory> make clean; make
