Jeff, I downloaded and install QT as you suggested, and created an environmental variable QTDIR as C:\Qt\4.6.0 (the installation directory). I then downloaded FreeSWITCH source via svn (v16230) and built it successfully. I then opened the FSCOMM project within the FreeSWITCH directory and attempted to build it. It failed with the messages below. Any ideas on what I might have done wrong? The environment is Windows 7/64.
