- Subject: different result on cross-compile on fc12 and fc13
Hi,
I have a develop board, which runs linux 2.6.35. The board is
connected to a fedora 12. I cross-compile the systemtap script to
generate trace.ko, and copy the trace.ko to run the instrumented code
on the board.
If I compiled the trace.ko on fc13, then everything is fine. The trace
log is generated correctly. But if I compiled the trace.ko on fc12,
whatever I use the stap on fc12 or compile a systemtap 1.4 myself, I
cannot see correct trace log on the board after running. The trace.ko
cannot generate any log from application, but only able to trace
probe.end.
I didn't see any compile error msg on fc12 system.
Any idea to solve this problem. I cannot drop fc12 now and don't want
to use another fc13 to compile the script.
Thanks,
Zhiwei
