I guess it is a trivial question, but failed to include my own classes into the CollectionTree class.
Lets assume my class is named CDemo with the corresponding files CDemo.h and CDemo.cxx. I include them in CollectionTree.h via #include “CDemo.h” and create an object as a member variable of CollectionTree.
In root I compile CDemo via “.L CDemo.cxx++” which works fine. In a second step I run the proof-marco (which compiles the CollectionTree class). So far so good.
The problem occurs if I want to run proof: I get the following errors in the log-files (here only one example):
/scratch/.tmp/pool/proofbox/session-81836-24247/worker-0.17-lx53/./fileLWonlX.o: In function
CollectionTree2::~CollectionTree2()': fileLWonlX.cxx:(.text._ZN15CollectionTree2D0Ev[CollectionTree2::~CollectionTree2()]+0x28): undefined reference toCDemo::~CDemo()’
Thanks in advance for the help!
