Setup Xcode and FLTK

Question

Errors I get when trying to build the first block of code on this page under Xcode

Undefined symbols for architecture x86_64:

"fl_define_FL_SHADO

Answer 1

I have found the solution at groups.google.com and below is what I have done:

1. Change build settings as such:

   Header Search Paths : -I/usr/local/include

   Library Search Paths : /usr/local/lib

2. Go to terminal and type fltk-config --ldflags

   You get a line of flags, mine was -L/usr/local/Cellar/fltk/1.3.2_1/lib -lfltk -lpthread -framework Cocoa.

   In Xcode Build settings, paste that in other linker flags

3. After these steps Xcode compiled the file successfully.
