[MPICH] Error compiling mpich2 on solaris with gcc, PTRACE_XXXX

[James S Perrin]

Hi,

I'm using :
	mpich2-1.05p4 source
	gcc 3.3.2
	Solris 9 (sunOS 5.9)

Configured as:
./configure --prefix=/opt/apl/sp/mpich2 --with-mpe --with-pm=mpd 
--with-device=ch3:ssm --with-thread-package=pthreads --disable-f77 
--disable-f90 --disable-cxx

make fails with the following error:

gcc -DHAVE_CONFIG_H -I.

The PTRACE_XXXX defines do not seem to be set on solaris, it uses 
explicit integer values for ptrace requests according to the man page.

shmproc.c has :

#ifdef HAVE_SYS_PTRACE_H
#include <sys/ptrace.h>
#endif

but does not #if..def the calls to ptrace or define PTRACE_XXXX instead. 
Looking at the source for shmproc.c in CVS this still seems to be the 
case (though it has moved to src/mpid/ch3/util/shmproc).

 From the little I understand after reading the man page only 
PTRACE_PEEKDATA seems to have and equivalent value on this system - 2. 
So there doesn't seem to be much that can be done, the man page in 
courages use of /proc for debugging purposes instead. So this is 
probably just a FYI.

I've successfully compiled using SUN Studio but MPICH2 doesn't currently 
support the ssm device for these compilers.

Regards
James
