However, Iâ??m stuck on how to re-run the cmake > program to update the relevant files? I'm not sure if I am understanding your question correctly, but the command "cmake" just updates the Makefile. In the build directory where you run cmake, a new Makefile is regenerated. Source code isn't recompiled. To do a recompile, you need to run "make" after "cmake". Indeed, if you've created a separate build directory (which you should always do to avoid cluttering up the source directory), you can always remove everything in that directory and redo the "cmake" and "make" steps. I think this is what you're stuck on? Ray ------------------------------------------------- This e-mail is sent by CUHK WebMail http://webmail.cuhk.edu.hk
