Hi Dave,

Yes, tcptk50.tar.F is matching the TCP/IP 5.10 run-time.

To localize your issue, please, build demo projects from tcptk50.tar.F bundle. 
They are located at /usr/tcptk/5.0/usr/demo/src/socket after installation. In 
case the issue occurs, post here your build log.

To answer my own question, incase anyone else wants to know.

The link failed as watcom  was unable to select the library automatically.

Looking at socket.h from the older 4.25 installation and the new one shows this pragma block..

#if defined __SW_3R
#  pragma library (socket3r)
# elif defined __SW_3S
#  pragma library (socket3s)
#elif defined __SMALL__
#  pragma library (sockets)
#elif defined __COMPACT__
#  pragma library (socketc)
#elif defined __MEDIUM__
#  pragma library (socketm)
#elif defined __LARGE__
#  pragma library (socketl)
#endif

Adding this back to the later socket.h cured my link issue.

Perhaps there is a better solution, but it works.

Dave.
