Hi,

I also encountered some problems compiling ccRTP with msvc 6.0.
1) I got the following error compiling duplex.cpp:
error C2247: 'Error' not accessible because 'ost::UDPSocket' uses 'public' to inherit from 
'ost::Socket'

I changed the return type of the following function
UDPTransmit::Error RTPDuplex::connect(const InetHostAddress &ia, tpport_t port) 
to RTPDUplex::Error.

2) compiling 'queue.cpp':
error C2065: 'O_RDONLY' : undeclared identifier

So I added at the top of this file the following include line:
#include <fcntl.h>

Now the code compiles but I get a bunch of linking errors:

I've tried the suggestions proposed in http://lists.gnu.org/archive/html/ccrtp-devel/2003-06/msg00000.html, but it didn't solve the problem. 
Has anybody some suggestions to solve this?
