Greetings! I have been working on the BID tutorial in writing the hiworld example. I was able to complete the exercise :) I just found one compilation error, in "4.3 Client helper library", where it said no member ipc_error for env. Declaration is as follows: CORBA_Environment env = dice_default_environment; One usage in the example is: return -env.ipc_error; I checked l4/tool/dice/include/dice/dice-corba-types.h and for l4x2 version, ipc_error is declared inside a _p union. Hence, the usage of: env._p.ipc_error worked fine. Is that correct? I tested hiclient and hiserver replacing demo-drops images with my compiled ones, and it worked fine. My documentation and the source code can be viewed from: http://www.shakthimaan.com -> fiasco Regards, SK -- Shakthi Kannan, MS Software Engineer, Specsoft (Hexaware Technologies) [E]: shakthimaan@yahoo.com [M]: (91) 98407-87007 [W]: http://www.shakthimaan.com [L]: Chennai, India __________________________________ Yahoo!
