CLHEP is a C++ class library for High Energy Physics supported by the Application Software group in IT division. A Reference Guide and a User Guide exist as documentation.
The CLHEP library is installed by default in the NICE server. It is located in Z:\P32\LHCXX\specific\Windows_NT\CLHEP\pro
The user of CLHEP under Visual C++ only needs to setup the INCLUDE and LIB path to the correct place. Using the Tools->Options command and under the tab Directories add the directory for the Include files to Z:\P32\lhcxx\specific\windows_NT\clhep\pro\include, and for the Library files add the directory Z:\P32\lhcxx\specific\windows_NT\clhep\pro\lib
Make sure that the settings for the project (Project->Settings..) are similar to the follwing figures.
