I can answer that second error with out even looking at the .cpp file.
Lets say you have code like this:
void bob ( const char h );
char *bob = "hello";
myfunc(bob[3]);
that would not work. bob[3] is a char, not a const char.
you would have to do this:
myfunc( const char(bob[3]) );
so to fix that error, typecast the variable to a const char.
