Hello Rene Can you say which compiler you are using at present? You mentioned MS Fortran compiler. That was dropped by MS about 5 years ago in favor of the Digital Fortran compiler (later known as Compaq Fortran Compiler. Are you sure ftp://root.tar.gz/root/pythia62win.tar.gz is a valid address It is a typo. It should be: ftp://root.cern.ch/root/pythia62win.tar.gz Valeri > -----Original Message----- > From: owner-roottalk@pcroot.cern.ch [mailto:owner-roottalk@pcroot.cern.ch] > On Behalf Of Rene Brun > Sent: Tuesday, July 22, 2003 5:27 PM > To: Nick van Eijndhoven > Cc: Rene Brun; ROOT discussion group > Subject: Re: [ROOT] Pythia6 business. > > Hi Nick, > > Concerning Pythia6 on windows: if you or a Windows guru > have time to investigate why pythia62 does not compile > under Xp with the .NET environment, you can take > ftp://root.tar.gz/root/pythia62win.tar.gz > and try to build the dll/lib using setpythia.bat. > This used to work under Windows/NT with the previous MS > Fortran compiler. > If somebody send me the necessary changes to make this dll, > I will be happy to include it in the next release. > > Rene Brun > > On Tue, 22 Jul > 2003, Nick van Eijndhoven wrote: > > > Hi Rene, > > I get your point, but I don't think it's pure accident that > > my stuff works under win98. > > The windows release of ROOT 3.05/06 doesn't have any TPythia6 > > stuff in; what I did was that I saved all the TPythia6 stuff > > (i.e. all .lib, .dll and corresponding header files like e.g. > > TPythia6Calls.h, TMCParticle.h etc...) from a previous version > > 3.04.
