[Linker Error] Error processing module JConsts.pas

Cause

Not sure, but I did both two things below:

Added the following line to support JPEGs, to only one of the implementation files (.cpp) that will need it:

#include <jpeg.hpp>

Or made a too difficult std::string concatenation

std::vector<std::string> v;

v.push_back(" " + m_question->m_filename + " ");

Not sure which one of the two hypothesized solutions is the real one. I just did both.

I added the following line to the other implementation files (.cpp) that will need it:

#include <jpeg.hpp>

I also broke apart the std::string concatenation

std::vector<std::string> v;

const std::string filename = " " + m_question->m_filename + " ";

v.push_back(filename);
