[zeromq-dev] ZeroMQ chat example runtime error in Windows MS Visual C++ 2005

[Martin Sustrik]

Hi,

We have no MSVC 2005 installation here so it's hard to say if there's a 
MSVC2005 related problem. Anyway, I recall someone have build the 
project using MSVC2005 some time ago.

Can you be more specific about what kind of runtime error you've got? 
Acces violation? Calling pure virtual function? Also, call stack 
backtrace would help to identify the problem.

Pthread library should not be used on Win platform. If you have a look 
at the code, you'll notice that the sections using pthread functions 
look like this:

#if defined ZMQ_HAVE_WINDOWS
  .... native Win32 call ...
#else
  .... pthread call ...
#endif
