The network plugin needs an external library which is currently not in the CS library packages, that's why the network plugin is not compiled on your machine and you got these error messages.
The library needed is HawkNL. You can download it from http://www.hawksoft.com/download/
, either the release 168 or 17b1 should be OK.
I personally could not manage to have the cel configure script detect if HawkNL was installed or not. In order to make it work, I hacked it with something like (as I remember):
- install the HawkNL .h and .dll/.so somewhere where it is visible when you compile and run nettest
- modify the cel/plugins/network/tcp/Jamfile file by removing the line "if $(HAWKNL.AVAILABLE) = "yes""
- compile and run
Note that the network plugin is still a work in progress. It is still missing some API changes and mostly an abstraction layer so that it works smoothly and easily with cel applications. I am the guy who wrote this plugin and I still want to work on it, but could not manage to find some time to do it. But it still something I really want to do...
