I had problems with my code which was causing errors because of gflags. So i decided to play with gflags repositories and linkings manually which seems that was a bad idea. Now I even cannot compile caffe.
While making it all this following command
make all -j $(($(nproc) + 1))
I am getting following error message.
.build_release/tools/convert_imageset.o: In function `_GLOBAL__sub_I_convert_imageset.cpp':
convert_imageset.cpp:(.text.startup+0x74): undefined reference to `google::FlagRegisterer::FlagRegisterer<bool>(char const*, char const*, char const*, bool*, bool*)'

I looked through Internet for some possible solutions in some git threads and some other threads . Nothing working. Any kind of help or suggestion will be highly appreciated.
The problem is solved by downloading gflags package and installing it manually. Using following commands:
$ tar xzf gflags-$version-source.tar.gz
$ cd gflags-$version
$ mkdir build && cd build
$ ccmake ..
- Press 'c' to configure the build system and 'e' to ignore warnings.
- Set CMAKE_INSTALL_PREFIX and other CMake variables and options.
- Continue pressing 'c' until the option 'g' is available.
- Then press 'g' to generate the configuration files for GNU Make.
$ sudo make -j4
$ sudo make test -j4
$ sudo make install -j4
