Re: Crypto++ 5.2.1 compilation error on VS 2005 beta 2

I've just checked in the latest Crypto++ source code to CVS. It should compile without errors now on Visual Studio 2005 beta 2, but may still trigger some warnings on it. It can also be targetted for x86-64 now, but I haven't checked in the project files because I'm not sure the project files can still be used by Visual Studio 2003.

Hi,
crypto++ 5.2.1 is successfuly compiling on my Visual C++ 6.0 platform, and now, when testing it on Visual Studio 2005 beta 2, I run into the 2 following errors:

I know Visual Studio 2005 is not yet suported (it is just a beta,
after all...), but still I thought it's worth checking with others if
someone has seen these errors before and if there's a quick workaround
for that.

Thanks
Alex
