The point of libfl is that it provides(among other things) a yylex().

Here we are going out of scope of my knowelge. If the yylex function
is defined in libfl.so, the only thing I would check is whether and
how it is exported. For example:
- is it defined static or extern? Maybe your compiler, or options
given to it implies a static declaration?
- ir it C or C++. I mean: is it exported with mangled name?
