[Ace-users] [ace-users] ACE 5.3 Linking problem in VS2008

[Douglas C. Schmidt]

Hi Nikola,

Thanks very much for your email.  Please make sure to send all
questions related to TAO or ACE to the ACE mailing list or ACE+TAO
newsgroup, rather than to me directly.

ACE 5.5 is also old.  I recommend you upgrade to ACE 5.6.2 or contact
one of the companies that provides commercial support for older versions
of ACE.

You should *definitely* build your software and ACE with the same C++ compiler!

Thank,
