Hi guys,

I have one problem on making pfmon-3.9. I know this question is kind of low level, but I have tried a lot of ways and no result.
The system  I am using is Ubuntu (2.6.38 kernel), and I have already installed libpfm-3.10 successfully.

The information for this failure is:

make[1]: Entering directory `/home/junjie/tools/PMU/pfmon-3.9/pfmon'

make[1]: *** [pfmon_symbols.o] Error 1
make[1]: Leaving directory `/home/junjie/tools/PMU/pfmon-3.9/pfmon'
make: *** [all] Error 2

Could anyone give me some hint or solution for this?
I have modified the config.mk according to the README.
