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/
