Hello,
For my work, I need the log_net server which only compiles with oskit. So I cannot abandon it.
There now is a replacement for log_net, called log_ore in l4/pkg/lib/uip/log_ore. It builds with dietlibc. This log_net replacement uses the ORe network switch to communicate over the network and could be a solution for you.
log_ore's LOG handling is mainly copied from l4/pkg/dmon (a log client for DOpE). At the moment there is only support for standard LOG messages. I'll be working on binary channels asap, because this is what I need for my diploma thesis.
So far Bjoern
