Compilable macros are : -----> TrkCalibQLookBasic.cpp (needed TrkCalibQLook_BASIC.cpp and TrkFunctions.cpp) -----> TrkCalibQLookExpert.cpp (needed TrkCalibQLook_EXPERT.cpp and TrkFunctions.cpp) -----> TrackerQLookBasic.cpp (needed TrkQLook_BASIC.cpp and TrkFunctions.cpp) -----> TrackerQLookExpert.cpp (needed TrkQLook_EXPERT.cpp and TrkFunctions.cpp) to compile enter the command ""ant" from a terminal in the this directory [... macros]$ ant the result will be four executable files TrkCalibQLookBasic TrkCalibQLookExpert TrackerQLookBasic TrackerQLookExpert in the directory TRACKER/bin NB: to compile correctly set the right paths in the initial part of the file build.xml NB: use the options "-h" or "--help" to known the input parameters
