Hi All, I met some problem when linking to libpfm. The error message was:
/usr/bin/python2.7 /home/yuhao/Documents/mozilla-release/config/ pythonpath.py -I../../config /home/yuhao/Documents/mozilla-release/ config/expandlibs_exec.py --uselist -- 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 -Wno-long-long -I/usr/local/ include -fno-exceptions -fno-strict-aliasing -std=gnu++0x -pthread - ffunction-sections -fdata-sections -pipe -DNDEBUG -DTRIMMED -g -Os - freorder-blocks -fomit-frame-pointer nsBrowserApp.o -lpthread -Wl,- rpath-link,/home/yuhao/Documents/mozilla-release/firefox-release/dist/ bin -Wl,-rpath-link,/usr/local/lib -Wl,--whole-archive /home/yuhao/ Documents/mozilla-release/firefox-release/dist/lib/libmozglue.a -Wl,-- no-whole-archive -rdynamic -L../../dist/bin -L../../dist/lib -lpfm -L/ usr/local/lib /home/yuhao/Documents/mozilla-release/firefox-release/ dist/lib/libxpcomglue.a -ldl -lpfm nsBrowserApp.o: In function `main': /home/yuhao/Documents/mozilla-release/browser/app/nsBrowserApp.cpp: 218: undefined reference to `pfm_initialize' /usr/bin/ld.bfd.real: firefox: hidden symbol `pfm_initialize' isn't defined /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 - Wno-long-long -I/usr/local/include -fno-exceptions -fno-strict- aliasing -std=gnu++0x -pthread -ffunction-sections -fdata-sections - pipe -DNDEBUG -DTRIMMED -g -Os -freorder-blocks -fomit-frame-pointer nsBrowserApp.o -lpthread -Wl,-rpath-link,/home/yuhao/Documents/mozilla- release/firefox-release/dist/bin -Wl,-rpath-link,/usr/local/lib -Wl,-- whole-archive /home/yuhao/Documents/mozilla-release/firefox-release/ dist/lib/libmozglue.a -Wl,--no-whole-archive -rdynamic -L../../dist/ 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 this?
