I must add a precision : only the platform is ia64. My development machine is ia32, and I do cross-compilation to compile my BIOS.
I never heard of this "vanilla Windows version of gdb", have you informations about it ? > >Hi people of Cygwin & GDB, > > > >I'm trying to do some quite complicated debug stuff with Cygwin, > and can't > >find how to do it.
