 If you get linker errors about undefined references to symbols that involve types in the `std::__cxx11` namespace or the tag
 `[abi:cxx11]` then it probably indicates that you are trying to link together object files that were compiled with different
-values for the _GLIBCXX_USE_CXX11_ABI marco. This commonly happens when linking to a third-party library that was compiled with 
+values for the _GLIBCXX_USE_CXX11_ABI marco. This commonly happens when linking to a third-party library that was compiled with
 an older version of GCC. If the third-party library cannot be rebuilt with the new ABI, then you need to recompile your code with
 the old ABI,just like:
