Please use Boost SVN trunk here:
https://svn.boost.org/svn/boost/trunk/boost/spirit https://svn.boost.org/svn/boost/trunk/libs/spirit
and make sure to put these directories in front of your normal Boost installation (V1.37 is required at minimum). The high_resultion_timer.hpp is here:
https://svn.boost.org/svn/boost/trunk/libs/spirit/benchmarks/ high_resolution _timer.hpp
Hi Hartmut, So, I did the following and placed them in different directories. $ svn checkout https://svn.boost.org/svn/boost/trunk/boost/spirit $ svn checkout https://svn.boost.org/svn/boost/trunk/libs/spirit In both cases it states "Checked out revision 55030". And shoved high_resolution_timer.hpp in the appropriate place. After modifying "uint_parser.cpp" to add #include <iostream> I get the following error: $ g++-4 -I ~/Desktop/boost_spirit/ -I ~Desktop/libs_spirit/ -I ~/ Desktop/boost_1_39_0 -o uint_parser uint_parser.cpp uint_parser.cpp: In function 'int main()': uint_parser.cpp:37: error: 'qi::int_' has not been declared uint_parser.cpp:104: error: 'int_' was not declared in this scope which seems fairly fundamental. Do I have the correct revision of Spirit? Any suggestions? -ed ------------------------------------------------ "No more boom and bust." -- Dr. J. G. Brown, 1997
