Unable to build any application that uses yaml-cpp, linker errors

[divyansh2681]

I am building an application that uses yaml-cpp but I get these errors:

/usr/bin/ld: CMakeFiles/transcribe.dir/transcribe.cpp.o: in function `returnVocabulary(std::string const&)':
transcribe.cpp:(.text+0x55786): undefined reference to `YAML::LoadFile(std::string const&)'

Facing the same issue, did you get a chance to find a work around/solution?

[divyansh2681]

In my case, the YAML file was very straight forward, so I parsed it as a text file and wrote a function to extract the data that I need from the file.

Can you try a different version? maybe the 0.7.0 ?
