There's a problem occuring on Linux systems due to incompatibility between RedHat 5.X and 6.X distributions. Binaries produced with 5.X are not fully compatible with 6.X. We observed several times problems on RH 6.X with CLHEP's Random when trying to save the engine status, and figured out that CLHEP needs to be recompiled with RH 6.X due to incompatibility of iostreams in the two systems. Please, check that you're using a CLHEP library built with RH 6.X. Concerning the problem in architecture.gmk for FCLIBS, this has been already fixed in the development version "config-V01-01-00". Thanks. |
