Dear Rooters Alos congratulations for 20000 downloads. I have a small problem using the attached shell script i tried to generate the files so that i can call cern library functions within root as described on the root web page. Unfortunately I am getting the following messages. Note: operator new() masked 1c Note: operator delete() masked 1c /tmp/cca024911.o: In function `main': /home/wenzel/root/test/rootCERN.cxx:27: undefined reference to `TRint::TRint(char *, int *, char **, void *, int)' Any idea what I am doing wrong here? cheers and thanks in advance for the help. hans wenzel IEKP Karlsruhe. #! /bin/tcsh -f rm -f CERNfunctions.h CERNLinkDef.h rootCERN.cxx CERN.cxx # # create CERNfunctions.h # cat >!
