I`m Roberto I work at Computer Science Departement at UCLA, I am new about this topic of research and I have been started for a month, now I`m studing the ixp1200. I read the documentation "tutorial" and the "Developer`s guide" and the book "ixp1200 Programming" but I have not the idea very clear. I was able to compile and to run the example of the tutorial. Now I would like to do something but I think the tutorial does not cover all the aspect, like IDL call and the use of Resource Manager. I also had some problem to compile the example of the bool chapter 11 when I compile, writing malke I recive the message: tao_idl:not found make[3]:***[source/idl/bridging_sk_c.c] Error 127 I ask if someone has other tutorial or some guides (made for internal purposes) or some programs that I could use as example for better understanding the ixp1200 functionaliti Last question, I remember to have read (but I don`t remember where) that if I don`t have the licence for Cmicrocode I can only compile tha programs for only degud purpose. Is it right? Thanks an advance for the reply Roberto Maccaferri
