Re: C++ help needed: singleton.hpp

[Klaus Spanderen-2]

Hi

I'm having this problem using Visual Studio Express 2005.

I nailed it down to a 15 line program (attached to this email), which
generates to wrong results when compiled within a separate Visual Studio
solution _and_ the option

Common Language Runtime-Support (/clr)

is switched on. Everything is okay as soon as I'm switching this option off or
declaring

inline T& Singleton<T>::instance() { ..}

instead of

T& Singleton<T>::instance() { }


cheers

Hmm. We might use the preprocessor to define the inline declaration
conditional to that particular compiler and option---I'd like to keep it
non-inline when possible, since inlining it might give problems on other
compilers. What do you think?

Later,
        Luigi

Klaus,
        I've committed a fix. May you try it and see if it works?

Thanks,
