Re: ROOT with Visual Studio 2008

Hi,

we strongly recommend to use ACLiC, and we discourage using the bare compiler by not providing detailed tutorials for it :-) But you seem to already manage to build, so what exactly are you looking for?

You can get rid of the warnings by adding w32pragma.h as a forced include (somewhere in Project / C++ settings). This will silence most of the warnings that we silence in ROOT, too, and you get compatible build settings.

The only and most important ingredient to remember is that you need a debug build of ROOT if you build a debug application, and a release build of ROOT if you build a release application. Microsoft has different debug / release C runtimes and STL implementations; they must match across libraries.

Cheers, Axel.
