Hello, If you want to use c++ library, then you can try to compile it by yourself: yum install cmake boost boost-devel boost-doc gtest gtest-devel protobuf protobuf-devel libicu libicu-devel $ cd libphonenumber/cpp $ mkdir build $ cd build $ cmake .. $ make $ ./libphonenumber_test cp -r libphonenumber.so* /usr/lib64/ cp -r libgeocoding.so* /usr/lib64/
