Strange, this is the first I've heard of this problem affecting C++. Can you possibly split your .proto into multiple files? It takes quite a monster of a file to produce a 64k descriptor, even when using lots of custom options. It seems like such a file would be hard to maintain anyway, so splitting it up would be a good idea.
Also, can you file an issue report? http://code.google.com/p/protobuf/issues/list On Wed, Apr 7, 2010 at 6:22 AM, Iiro <iiro.hiet...@gmail.com> wrote: > The problem seems to occur with Visual C++ 2008 also.
