Hi,
I am trying to load and run the attached demo script but get the following errors. (The script does a minimization with minuit2). I have tried with ROOT 5.18 on an UBUNTU Linux machine, and ROOT 5.18 and 5.20 on a Windows XP machine.
with CINT- .L Quad4FMain.cxx
the error is- Limitation: Reference member not supported. Please use pointer minuit2/abobj.h(98)
with ACLiC- .L Quad4FMain.cxx +
the error is- ‘cl’ is not recognized as an internal or external command, operable program or batch file. Error:external preprocessing failed… Error: C:\root\bin\rootcint: error loading headers… Error in : Dictionary generation failed…
Any assistance will be greatly appreciated.
Thanks,
Warren

. ACLiC calls the installed compiler (Microsoft’s C++ compiler on windows) and hence this compiler needs to be setup properly.
