Peter has pointed out that the TrackFitterLikelihood is not compiling in the MarlinTPC trunk (sorry about that).

The problem is that it uses the newest version of Minuit. It is C++ based and written at CERN.

At the time I wrote the Fitter a standalone version of Minuit was available. It has no dependencies on outside packages. I compiled it and used that version.

Now it is available as a part of ROOT (5.08.00) as ROOT::Minuit2.

This leaves three options that I can see.

1) Including the standalone version with the Fitter (along with hopefully including it with the gmake process)

2) Adding ROOT as a dependency to MarlinTPC (ugly)

3) Using the standalone FORTRAN version of Minuit.

1 and 2 can probably be combined with clever programming. Which is the most likely case? Do many people already have ROOT installed and this would not be a problem?

Thank you for your input.
