- Subject: print_ubacktrace() and ppc 32
Hi all,
I am using systemtap userspace probes on a 32-Bit powerpc architecture. I do
crosscompile the probes on a 64-Bit x86 host.
The version I use is:
Systemtap translator/driver (version 2.3/0.152, non-git sources)
If I use print_ubacktrace() in my stap script it won't compile. I am getting two
main error messages and I ask myself which one tells me the real reason for the
error:
backtraces for 32bit programs on 64bit kernels don't work.
systemtap-2.3-32645/share/systemtap/runtime/stack.c:85:2: error: #error
"Unsupported architecture"
So is userspace backtrace not supported at all for PPC? Or does the problem come
due to a misconfiguration in my setup because I crosscompile on a 64 Bit host
architecture for a 32 Bit target architecture?
Regards
Holger
