sun4u should be sun4u. I do all my builds on a Netra t1 and deploy the
resulting binary on 20 E450s.
But they all run Solaris 8.
I am also the one "responsible" (if you can call it that) for Ganglia's
performance (or lack thereof) on the Solaris platform. My development
environment was gcc 3.0 on Solaris 8, testing on E450s and the
aforementioned Netra.
If memory serves me correctly, the kstat and kvm_* calls don't actually
have any OS-revision-specific magic numbers in them. kvm_* reads from
/dev/ksyms for all its offsets and kstat uses a set of abstracted strings
(as you can see in the gory debug output) to handle queries.
I'm a little disappointed that I didn't see my "kvm_read() failed, I'll
probably segfault soon..." message in there, but that only pops up when a
32-bit kvm_read() sees a 64-bit /dev/ksyms. :)
I haven't upgraded my build box to gcc 3.2, although I probably should...
maybe that would cause these problems to pop up.
And before you ask, I don't have a Solaris 7 SPARC box handy... :)
Although my code in solaris.c isn't the finest, it's been very stable and
people have apparently been using it in production elsewhere without any
major problems, so I am not going to put on my code spelunking hat quite yet...

Does anyone have 64bit solaris7 binaries of ganglia which will work on a
particular platform (sun E450 5.7 Generic_106541-18 sun4u sparc
SUNW,Ultra-4)?
I have managed to compile in most cases (various solaris 8 machines and a
solaris7) but this one platform is eluding me. I tried compiling with gcc
3.2 (sunfreeware.com) on this platform
5.7 Generic_106541-18 sun4u sparc SUNW,Ultra-60
thinking the interface would be binary compatible with the same major kernel
number?
The output from this when I run with debug level 100:

Is there a way I can get this to work without compiling gcc itself on the
target machine ?
If there is an accepted way of building these I am happy to provide/maintain
solaris packages for ganglia as long as it isn't too painful.
Cheers
