Using TTreeFormula, root-config --libs in root 6.00/00

ROOT
1

Hello,

I’m trying to use a TTreeFormula in a C++ program using root 6.00/00 librairies. But if I try to compile this simple dummy program:
UseTTreeFormula.C (106 Bytes)
using the following line (I have gcc 4.8.2):

g++ UseTTreeFormula.C -o UseTTreeFormula `root-config --cflags` `root-config --libs`

I obtain:

/tmp/ccf6ZiIN.o: In function `main': UseTTreeFormula.C:(.text+0x1c): undefined reference to `TTreeFormula::TTreeFormula()' collect2: erreur: ld a retourné 1 code d'état d'exécution
I solved the problem by addind -lTreePlayer:

g++ UseTTreeFormula.C -o UseTTreeFormula `root-config --cflags` `root-config --libs` -lTreePlayer

So, would it be possible to add -lTreePlayer in the root-config --libs and root-config --glibs scripts for the future releases?

Thanks,
Timothée

Hi Timothée,

this is a nice suggestion: thanks.
A little comment about your commandline. You can make it more compact if you like:

g++ mySourceFile.cpp -o myExecutable `root-config --cflags --libs --cflags`

without the need of N invocations of root-config

Cheers,
