I solved the problem by also installing g++-5 and setting CC variable to gcc-5 and CXX variable to g++-5. But now I have a new problem: although I have installed packages sparsehash 1.10-1ubuntu1 and libsparsehash-dev 1.10-1ubuntu1, the configure script does not see them

Here is the output, I attach the config.log file

Please post the _entire_ output of the ./configure script, together with
the config.log file.
