Gflags Compile time error

I am trying to compile file which have GFLAGS inside. My compiling command :

g++ -I ../eigen-eigen-b9cd8366d4e8/ -I/caffe_path/distribute/include  my_file.cpp -std=c++0x   -lpthread -lglog -lboost_system -DUSE_OPENCV

My error message is:

/usr/bin/ld: /tmp/ccv5GAaZ.o: undefined reference to symbol '_ZN6google26ShowUsageWithFlagsRestrictEPKcS1_'
//usr/lib/x86_64-linux-gnu/libgflags.so.2: error adding symbols: DSO missing from command line

It is my first time working with Gflags. Based on the suggestion on internet i tried to comment lines with#ifndef and #endif in the following lines but it did not help.

#ifndef GFLAGS_GFLAGS_H_
  namespace gflags = google;
#endif

I also tried suggestions on this thread , but it did not fix anything.

The gflags installed inside the caffe and seperately were somehow causing conflict. Uninstalling any of them did not help. Solution for me was uninstallation (all) of the whole caffe and gflags (internals and externals) solved the problem. When I was sure that there is no trace of gflags/glogs and caffe on my system I was able to install caffe again.
