Hi guys,  
I’m trying to write a plugin for freefem++. And I found I must link with libff.dll. But I can’t find the import library (libff.lib).  
BTW I’m using the installation of FreeFem+±4.14-dev-win64.exe downloaded from Github.  
Many thanks!

on window,

1. first you must have installe msys2 and use the ff-c++ script to compile  
we use g++ and g++ do not need libff.lib)

the lib libel.dll is created in src/bin-win32 directory.
