[Botan-devel] Linking error [SOLVED]

[Joel Low]

Actually, I think nothing has to be done. It is more likely that you sent
the wrong compile flags when compiling your client program instead of
compiling Botan.

The confusion occurs because in the Visual Studio IDE /MD is default for
release and /MDd is default for debug. When building from the command line
/MT is default and /MTd is default for debug.

All VS 2005 libraries are now multithreaded, there are no more
single-threaded libraries.
