Enter debugger
by ahmad kamal 17 Jan '08

17 Jan '08

Hi mates, Any idea how to enter debugger when running fiasco other than put a debug statements in the codes? For example, in OKL4 we can enter the debugger by pressing ESC key? ____________________________________________________________________________________ Never miss a thing.

Problems creating IDL
by Lucyantie Mazalan 16 Jan '08

16 Jan '08

Hi all, I have been creating a package which implements a server invoked by a client. I understand from the tutorial that I have to create an IDL file listing all my public function there. Problem here is that, I would like to know whether I really need to do the IDL file or can there be other way that I can actually skip the IDL and how do I do that, since my intention here is just to create a simple communication with purpose between my server and client using 1 same language, C. Please advice me in this. Thanks, Lucillle. ------------------------------------------------------------------ - - - DISCLAIMER: This e-mail (including any attachments) may contain confidential information.

sigma0 and tbuf
by Marc CHALAND 11 Jan '08

11 Jan '08

Hi, I tried to use fiasco without jdb. It works fine, but, at boot time, sigma0 issues an int 3. After some analysis, int 3 is generated by init_memory in init_mem_v2.cc. It calls fiasco_get_status_phys(). If I comment this, everything is then fine. Why this call is for ? Regards Marc
