Hi,
I have created a program called tpcdata where I am using also Root functions, and so for that I have included the Root header files as
#include “TH1.h” for example…
For compiling it I have created the following Makefile:
tpcdata: tpcdata.cxx
g++ -I/afs/cern.ch/sw/root/v3.05.07/rh73_gcc32/root/include -L/afs/cern.ch/sw/root/v3.05.07/rh73_gcc32/root/lib -lCore -lCint
-lHist -lGraf -lGraf3d -lGpad -lTree -lRint -lPostscript -lMatrix -lPhysics -lpthread -lm -ldl -rdynamic -o tpcdata tpcdata.cxx
Then I compile it and get the desired executable tpcdata.
But then when I try to run it I get the folowing error message:
tpcdata: relocation error: tpcdata: undefined symbol: _ZN8TStorage11ObjectAllocEj
It seems that maybe there are some problems with the libraries?!
If I trype ldd -r tpcdata:
libCore.so => /afs/cern.ch/sw/root/v3.05.07/rh73_gcc296/root/lib/libCore.so (0x00111000)

undefined symbol: _ZN5TFileC1EPKcS1_S1_i (./tpcdata)
This is what I get!! Why it is trying to find the libraries in /afs/cern.ch/sw/root/v3.05.07/rh73_gcc296/root/lib
when I explicity pointed in the Makefile to -L/afs/cern.ch/sw/root/v3.05.07/rh73_gcc32/root/lib ???
Is this the problem??
Thank you very much for your help…
