Dear Members,

I am trying to use systemtap on Pandaboard with Linaro Ubuntu 13.04 version. http://releases.linaro.org/13.04/ubuntu/panda

I have installed systemtap & other dependencies by apt-get. And followed the instructions below.

https://wiki.linaro.org/Platform/DevPlatform/Tools/Systemtap

Simple script to test systemtap: stap -k -v -e 'probe vfs.read {printf("read performed\n"); exit()}'

It failed at the step 4(pass) to compile the code. By default -Werror flag is also enabled by stap. I guess that would be the cause. Also there are few other errors.

Please find the compilation error message below & let me know how to solve this. Thanks in advance.
