Note that you need -fPIC to build shared libraries.
I did this and succeeded:
% g++ -O2 -c ugur4.cpp  -o ugur4.o -DUSE_DOUBLE `fltk-config --cxxflags` -fPIC
ugur4.cpp:47: warning: deprecated conversion from string constant to ‘char*’
ugur4.cpp:47: warning: deprecated conversion from string constant to ‘char*’
ugur4.cpp:47: warning: deprecated conversion from string constant to ‘char*’
% g++ -shared -o ugur4.so ugur4.o `fltk-config --ldflags`
