building error when linking to one more library

Hi All,

I met some problem when linking to libpfm. The error message was:

/usr/bin/python2.7 /home/yuhao/Documents/mozilla-release/config/ -I../../config /home/yuhao/Documents/mozilla-release/
config/ --uselist -- c++ -o firefox -fno-rtti -

usr/local/lib /home/yuhao/Documents/mozilla-release/firefox-release/
dist/lib/libxpcomglue.a -ldl -lpfm

nsBrowserApp.o: In function `main':
218: undefined reference to `pfm_initialize'
/usr/bin/ld.bfd.real: firefox: hidden symbol `pfm_initialize' isn't
/usr/bin/ld.bfd.real: final link failed: Bad value
collect2: ld returned 1 exit status

This doesn't make sense to me. I specified the library name (-lpfm),
as well as the path for the linker to find it (-L/usr/local/lib). I am
sure these paths are correct.

I also tried not to use the python script, but just normal building:

c++ -o firefox -fno-rtti -pedantic -Wall -Wpointer-arith -Woverloaded-
virtual -Wsynth -Wno-ctor-dtor-privacy -Wno-non-virtual-dtor -Wcast-
align -Wno-invalid-offsetof -Wno-variadic-macros -Werror=return-type -

bin -L../../dist/lib -lpfm -L/usr/local/lib /home/yuhao/Documents/
mozilla-release/firefox-release/dist/lib/libxpcomglue.a -ldl -lpfm

And it just worked. So I assume the problem was with the python
script. I am not familiar with python, so could anyone help me with
