Hi, I searched in the roottalk archive for the problem I have encountered and I see that it has been discussed before, but there did not seem to be any clear resolution as far as I could see. I installed root version 2.25/03 on my NT desktop at work which seems to work fine if I set the ROOTSYS variable and add %ROOTSYS%\bin to my PATH. I installed exactly the same version on my laptop which is running Windows 98 and find that root does not work correctly unless I am running it from the directory containing the binaries. The problem is not in finding root.exe but in finding the .dll files which are in that directory. There was some discussion in roottalk about .rootrc files and setting the dynamic path correctly but I could not find a definitive answer to tell me how to make root work sensibly under win98, i.e. 1. What should the necessary configuration file be called ? 2. Which directory should it be in ? 3. What must it contain to be able to find the .dll files from anywhere ? The zip file containing the windows 95/98/NT version has a file called system.rootrc (not just .rootrc) located in the top level directory ( %ROOTSYS% ) which contains the following lines: # Path used by dynamic loader to find shared libraries and macros # Paths are different for Unix and Windows. The example shows the defaults # for all ROOT applications for either Unix or Windows. Unix.*.Root.DynamicPath: .:$(ROOTSYS)/lib Unix.*.Root.MacroPath: .:$(ROOTSYS)/macros WinNT.*.Root.DynamicPath: ./;$(ROOTSYS)/bin;$(PATH) WinNT.*.Root.MacroPath: ./;$(ROOTSYS)/macros Should this work for Windows 98 ? (I am not even certain that it is looked at by the root executable.) If not, then how must I change it to make it work ? I should point out that I am also just beginning to try to learn how to use root so don't even have any past experience from other platforms to help me. Thanks for any help you can give.
