Hello ROOT authors,
Recently I got a PC and was happy by the idea of working with ROOT
on PC having a machine for me alone. Unfortunatly, I did not succeed
100%. First this is what I succeed in :
(1) - installation of ROOT on the PC.
(2) - installation of my code under Visual C++ with a makefile. I
could compile my code, link it with the ROOT libraries and execute it
ok.
This is what went wrong :
I had the surprise to discover that Visual C++ disables the debugger
when one enter in Visual C++ with a makefile ( which is a non-standard
way of using Visual C++ ). So I tried to make, very painfully, a
"developer studio project". I had to find which were the libraries
behind the "guilibsdll", how to indicate to Visual C++ where to find the
include files, and so on. I never succeed in linking my code that way. I
give at the end of this message the kind of error messages I get, but I
think it is much too complicate to try to solve this kind of problem by
mail, so the aim of this mail is to kindly ask the Authors of ROOT to
provide on the web some documentation about the use of ROOT in Visual
C++. For me the use of a debugger is essential and I return to unix on
HP, where the debugger dde is working quite well, until I know how to
get the debugger of Visual C++ to work. Thanks a lot if you can help me.
