Does somebody know what is going wrong on gcc 3.X machines?

Hi Stefano

I changed some of the code (change or add include statements) to be compatible with root v5.16.
In TpcPatternRecoTask.cxx i add a

#include <cmath>
using std::fabs;

which results in the shown error message on systems with gcc 3.
The error occurs because you want to get the absolute value of a
boolean variable, but this function is not implemented and i don't
know if this makes sense.

Maybe Christian or Sebastian can have a look at the problem.

Ciao

Florian
