undefined reference to `YAML::detail::node_data::end()'

[marvin2k]

When building this, I get:

      liblib_config.so: undefined reference to `YAML::detail::node_data::end()'               
      liblib_config.so: undefined reference to `YAML::Load(std::string const&)'               
      liblib_config.so: undefined reference to `YAML::detail::node_data::begin()'             
      liblib_config.so: undefined reference to `YAML::LoadAll(std::string const&)'            

where my linker-call is

/usr/bin/c++    -std=c++11 -O3 -DNDEBUG    CMakeFiles/lib_config_bin.dir/Main.cpp.o  -o lib_config_bin -rdynamic -lboost_system -lboost_system -lboost_filesystem -lboost_filesystem -lboost_regex -lboost_regex .../install/lib/libyaml-cpp.so liblib_config.so -lboost_system -lboost_filesystem -lboost_regex .../install/lib/libyaml-cpp.so -Wl,-rpath,.../tools/lib_config/build/src:.../install/lib 

After remaking external/yaml-cpp, I get a whole lot of other compiler-errors -- probably yaml-cpp-0.3 vs 0.5 fuckup? jesses... All in an entern bootstrap....

Yep 03 vs 05. external/yaml_CPP may not be installed

[marvin2k]

Which one? external/yaml_CPP? external/yaml-cpp? autoproj only knows external/yaml-cpp, which installs version 0.3

[jmachowinski]

external/yaml-cpp may not be installed (e.g. version 0.3)
