Your code is very hard to read since you didn't bother using code tags.
And you didn't indicate which line the error refers to. I can't see it.
And you didn't bother to say what the program does, either.

Why all the C-strings, you really should be using C++ strings instead of the C-strings and vector of char.

The std::map stores its elements in std::pair so you need to pass a std::pair<vector<char>, vector<char>> as argument to insert.

subt.insert({lineWords[0], lineWords[1]});

Alternatively you can use emplace which will forward the arguments to the std::pair constructor.

subt.emplace(lineWords[0], lineWords[1]);
