CRNN compile error with latest fblualib and thpp

Hi, I am running into a problem compiling TB++:

[ 50%] Building CXX object CMakeFiles/crnn.dir/ctc.cpp.o
/home/john/TextBoxes_plusplus/crnn/src/cpp/ctc.cpp: In instantiation of ‘int {anonymous}::forwardBackward(lua_State*) [with T =                float; lua_State = lua_State]’:

     const thpp::Tensor<T> input     = fblualib::luaGetTensorChecked<T>(L, 1);

This error is referenced here as well. I believe you have modified the CRNN code so I don't think I can use the latest version of CRNN that resolves this. One way that someone got it to compile (see reference) was by downgrading fblualib and thpp. Is this the route you would take or do you know of a cleaner way?

Thanks in advance and appreciate you sharing your software.

I was able to compile by install on ubuntu 14.04
