[Boost-users] RTTI for VC 6

VC 6 has an option for Run-Time Type Information (RTTI) that is normally off. I was able to compile and execute a sample program that had a problem. I noticed that Boost uses RTTI (such as the dynamic_cast operator), so I checked to see if the option was on; it was not. I turned the option on and the program worked. That problem is probably a known problem, but something such as the following can be added somewhere to not allow a VC 6 program to even compile if the RTTI option is off. I think it could make things a little easier for some beginners. # if !defined(_CPPRTTI) # error "Boost requires use of RTTI" # endif
