Can I run setup by myself? Currently, 'long long' type is supported by some computer platforms but not al l.So, I separated implementation of 'long long' into a different DLL. It is currently tested only on Linux and Windows-NT/9x. For other platforms, long.dl should be built with minor modification it the platform supports 'long long'. To do so, you need to download cint source package from http://root.cern.ch/Cint.html You need to copy $CINTSYSDIR/include/long.dl to $ROOTDIR/cint/include/long.dl. If you successfully build long.dl in other platform, please let me know and give me that change you made. Rene askes why using this platform dependent method. Because 'long long' is platform dependent itself. This is inevitable for now I think. There are still many ROOT running platforms which do not have 'long long'. I guess ROOT has 8 byte integer type. It would be better using it. (Is this correct Fons?) Masaharu Goto
