Resolution:

For Ubuntu 12.04
with g++ 4:4.6.3-1ubuntu5.

sudo apt-get install scons scons-doc

Now use scons to build google-gtags.
But first there are g++ header missing problems:

In filename.h:
#include <string.h>

In tagsutil.h
#include <cstdlib>

In iterators.h
#include <cstdio>

In symboltable.h
#include <cstring>

In file.h
#include <cstdio>

Now execute scons to build google-gtags.
scons

NOTE: There is one more warning message:

g++ -o gtags.o -c gtags.cc

On emacs gtags-find-tag fails even after restarting gtagsmixer:

gtags-cannot-connect: Cannot connect to mixer.  Please type M-x 
gtags-restart-gtags-mixer and try again.

On Ubunntu 14.04, still cannot build (with scons and the header edits described 
above).
