Hi
The problem is rooted in a change from the Solaris 2.5 to Solaris 2.6
version of
/usr/include/stdio.h !
One version uses sys/va_list.h, the other doesn't.
When you build gcc/egcs the prevailing system include files are copied and
patched
up in to the gcc/egcs tree. This works just fine so long as you run on the
same
`ptarch` as your distribution. However if you mix and match, you find that
you get
precisely your problem, the cloned stdio.h references a missing system file.
I thought this was a problem we created on our site. It appears to be a
problem
with the distributed pre-built binary. It claims to be Solaris 2.5 when
actually
it has Solaris 2.6 include files.
Rebuilding from scratch on the machine with the required OS is then ok, but
you
will need to have both a sol2.5 and a sol2.6 variant to support both
correctly.
Incidentally, if you want sol2.6.cfront you need to reorder the lines of
$PTOLEMY/mk/config-sol2.6.cfront.mk to get the ARCHFLAGS definition after
the
include (just like in config-sol2.5.cfront.mk). All except xv then builds
with
only vast numbers of warnings.
