Hi, I think it is not so hard to eliminate Ruby dependency from Trema. You may develop and run your controller application without Ruby as follows:
(1) Create a Makefile to build libtrema.a and core modules (switch_manager at least) (2) Build libtrema.a and core modules with the Makefile (3) Write your controller in C (4) Build your controller which links with libtrema.a (5) Run your controller manually or by a script like follows: $ mkdir -p /somewhere/tmp/log; mkdir /somewhere/tmp/pid; mkdir -p /somewhere/tmp/sock $ export TREMA_HOME=/somewhere $ /somewhere/switch_manager/switch_manager --daemonize --port=6633 \ --switch=/somewhere/switch_manager/switch -- \ port_status::your_app packet_in::your_app state_notify::your_app vendor::your_app $ /somewhere/your_app/your_app --name your_app --daemonize Regards, CHIBA Yasunobu (2012/02/15 23:24), Simon van der Linden wrote:
Hello, I'm looking for an elementary library to implement a controller in C. I would like not to depend on Ruby as Trema does (AFAIK the only controller framework for plain C). I have seen the small controller in the OpenFlow reference implementation, but at first glance the basic protocol implementation does not seem exported. I would appreciate if someone could point me to such a library. Otherwise I will work on extracting the useful bits from Trema for instance in order to create one.
