Hello Rooters,
I used Rene Brune's macro listed below as test macro (krecik.cxx). It's a
standalone program creating ROOT Tree. It's working fine on older version
of Linux, but it doesn't work on RedHat 5.0 because probably new version
of glibc. I hoped that the problem will be solved in new ROOT v.2.0, but
unfortunetly, it's also there. I'm looking for temporary solution of that.
How convert the standalone program (krecik.cxx) in ROOT macro krecik.C ?
This is an error output on ROOT v.2.0
