[OpenBIOS] Cross-compiling and testing sparc64 on Mac OS X

[Andreas Färber]

Hello guys,

It's awesome seeing you've made some progress towards emulating  
Solaris/sparc64!

However trying myself, compiling on Mac OS X (after making sure that  
NEED_INT128_T is defined) fails with the following error:

  HOSTCC host/kernel/bootstrap.o
In file included from ../include/openbios/sysinclude.h:7,
                  from ../kernel/bootstrap.c:9:
/usr/include/stdlib.h:267: error: syntax error before ‘arc4random’
make[1]: *** [host/kernel/bootstrap.o] Error 1

The return type of arc4random is u_int32_t, which is defined (in my  
case) in <ppc/types.h>. Not sure what goes wrong there. I thought it  
could be a name clash with OpenBIOS' __TYPES_H (malc would be  
furious!), but - luckily - Apple uses __TYPES_H_ for their _types.h.  
Anyway, not having these functions declared by defining  
_POSIX_C_SOURCE made the compilation proceed with only one warning:

  HOSTCC host/kernel/bootstrap.o
../kernel/bootstrap.c: In function ‘interpret_source’:
../kernel/bootstrap.c:529: warning: implicit declaration of function  
‘strcasecmp’

If I symlink .../share/qemu/openbios-sparc64 to .../obj-sparc64/ 
openbios-builtin.elf (or copy it over) I get this at runtime:

qemu: fatal: Trap 0x0010 while trap level (5) >= MAXTL (5), Error state

This looks different from what you've posted and is identical with  
QEMU's version of openbios-sparc64. Same with or without -nographic.

Any ideas?

Regards,

Andreas
