Complete Example Yaml program on http://code.google.com/p/yaml-cpp/wiki/HowToParseADocument does not compile

Question

Using G++ 4.6.2 on Linux Library was built according to instructions. run_tests in test directory works fine.

setenv YAML_HOME /nfs/site/proj/dt/ltt_test_15/work_area/ironchef/new_version/ironchef/trunk/yaml/yaml-cpp-0.5.0

ls $YAML_HOME total 640 16 CMakeCache.txt 0 build/ 0 libyaml-cpp.so.0.5@ 8 test/ 8 CMakeFiles/ 8 cmake_install.cmake 480 libyaml-cpp.so.0.5.0* 8 util/ 16 CMakeLists.txt 0 include/ 8 license.txt 8 yaml-cpp.pc 8 CTestTestfile.cmake 8 install.txt 8 matt_sandbox/ 8 yaml-cpp.pc.cmake 40 Makefile 0 libyaml-cpp.so@ 8 src/

cd matt_sandbox g++ -o test_yaml -g -I/usr/intel/pkgs/boost/1.48.0-gcc-4.6.2/include -I$YAML_HOME/include -I$YAML_HOME/include/yaml-cpp -I$YAML_HOME/include/yaml-cpp/node -I$YAML_HOME/include/yaml-cpp/node/detail -I$YAML_HOME/include/yaml-cpp/contrib main.cpp

That example uses the old API (version 0.3.0), but you're using the new API (version 0.5.0). I've updated the main page to make that clear.

For examples using the new API, see http://code.google.com/p/yaml-cpp/wiki/Tutorial.
