#aptitude search fltk|grep dev

p   libfltk1.1-dev                  - Fast Light Toolkit - development files    
p   libfltk1.3-dev                  - Fast Light Toolkit - development files

Why to choose one over another?

Solution

From version history:

This is basically FLTK-1.1.10 with extra features, but with an incompatible ABI. The new features include: full UTF-8 Unicode support, which allows left-to-right non-Latin text such as Greek and Cyrillic; new Fl_Tree, Fl_Table and Fl_Native_Filechooser widgets; printing support; a device abstraction layer; and a new progamming manual generated from the code using Doxygen.

As you see, you have now:

  • A new ABI that is incompatible with the old
  • UTF-8/Unicode
  • New tree, table, and filechooser widgets
  • Printing
  • Device abstraction(new implementation)
  • Programming manual from Doxygen

The OP also describes memory usage differences:

I also noticed 1.1 used 3 MB and 1.3 46 MB
