Compilation errors in compiling C++ Analyzer with ROOT Linux libr aries

Hi,

I am trying to use the THaCutList & THaVarList classes, which are dependent on ROOT framework.

I have installed the latest binaries of production version (5.16) of ROOT root_v5.16.00.Linux.slc3.gcc3.2.3.tar.gz. Whereas, the C++ Analyzer component which uses ROOT is version 1.4.7. I compiled the analyzer source code and my test program on "Red Hat Enterprise Linux AS release 3 (Taroon Update 4), 2.4.21-9.0.1.Elsmp" having "gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-24)".

Analyzer source code got compiled fine, but when I tried to compile my test program (given below), I got multiple undefined references errors. I have added the required ROOT libraries for linking in the compilation command. Few of them are given below.

May I please know, why these errors are coming? Do I need to compile the ROOT source also with the same compiler? Do I need to use any additional components or libraries for this compilation to happen?

Please help.

Thanks and Regards,
Ganesh
