Re: Met Problem on Enable SystemTap on Android

Thanks Turgis.

The fixed the -D problem. However, new problem comes out.

I tried to cross-compile the syscall_by_pid.stp but stuck on phase 4.
So I tried the most simple script helloworld.stp, but it still does
not work. I reinstalled the systemtap host and target tools, and I
double checked the ptrace.h and kernel compilation flags. Nothing
seems to be wrong.

The commands I run are:
./stap -gv -a arm -D OMAP_L25 -B
CROSS_COMPILE=~/Downloads/arm-2008q3/bin/arm-none-linux-gnueabi- -r
/home/lwan1/WORKING_DIRECTORY/kernel -I
/data/systemtap-1.5-macharm/share/systemtap/tapset/ -R
/data/systemtap-1.5-macharm/share/systemtap/runtime/ -m
syscalls_by_pid ~/Downloads/syscalls_by_pid.stp

and

./stap -gv -a arm -D OMAP_L25 -B
CROSS_COMPILE=~/Downloads/arm-2008q3/bin/arm-none-linux-gnueabi- -r
/home/lwan1/WORKING_DIRECTORY/kernel -I
/data/systemtap-1.5-macharm/share/systemtap/tapset/ -R
/data/systemtap-1.5-macharm/share/systemtap/runtime/ -m helloworld
~/Downloads/helloworld.stp

As the error message is too long, I saved them in .txt files and
attached them here.

Please check them up, and help me get through this procedure.

Any hint would be warmly welcomed.

Thank you very much.

Yours
Sincerely
