Hi
In my feeble and ignorance, I'm attempting to build CogVM on OpenBSD.
I've come across some problems that my limited skills cannot solve.
$ make

-DCOGMTVM=0 -DDEBUGVM=0 -I/usr/X11R6/include -I/usr/local/include

And the offending code is >>
#if COGVM
/* If we're in generated machine code then the
only way the stack
* dump machinery has of giving us an accurate
report is if we set
* stackPointer & framePointer to the native
stack & frame pointers.
*/
# if __APPLE__ && __MACH__ && __i386__
void *fp = (void *)(uap ? uap->uc_mcontext->ss.ebp: 0);
void *sp = (void *)(uap ? uap->uc_mcontext->ss.esp: 0);
# elif __linux__ && __i386__
void *fp = (void *)(uap ?
uap->uc_mcontext.gregs[REG_EBP]: 0);
void *sp = (void *)(uap ?
uap->uc_mcontext.gregs[REG_ESP]: 0);
# elif __FreeBSD__ && __i386__
void *fp = (void *)(uap ? uap->uc_mcontext.mc_ebp: 0);
void *sp = (void *)(uap ? uap->uc_mcontext.mc_esp: 0);
# elif __sun__ && __i386__
void *fp = (void *)(uap ? uap->uc_mcontext.gregs[REG_FP]: 0);
void *sp = (void *)(uap ? uap->uc_mcontext.gregs[REG_SP]: 0);
# else
# error need to implement extracting pc from a ucontext_t on this system
# endif
char *savedSP, *savedFP;
ifValidWriteBackStackPointersSaveTo(fp,sp,&savedFP,&savedSP);
#endif
I have got ucontext.h from src and stuff. Anyway. I want to know what
on earth I should do with call stacks and ucontext and what all this
is... Somebody educate me. I need to be schooled.
Many thanks
Dusty
