RE: [OpenBIOS] How to enable print statement in the openbios-kernel?

==>So you are not cross compiling?
 
No, I am using GCC for compilation
 version - gcc-g77-2.96-110

==>So you cannot even build all of openbios on your machine?

When I compile the kernel with option "#define DEBUG_CONSOLE"
(/kernel/include/config.h), it compiles fine.

But, If I add single "printk" statements in the each of the functions
processxt(), next(), enterforth() in the file /kernel/kernel/internal.c
it hangs....

ALSO

If I add DEBUG_INTERPRETER OR DEBUG_INTERNAL it still hangs....the
output I have mailed at the bottom.

These are the inner heart of the forth kernel and they are running very
often! If you put debugging in there, the resulting forth kernel will
become really slow. (by a factor of 100-1000 i might guess wildly)
Thus bootstrapping the device interface, which is the biggest part of
OpenBIOS, takes almost forever.
