Hi, I am using Xcode 4 and trying to set up FLTK 1.3.0 to run Bjarne Stroustrup's Chapter 12 FLTK Demo at the end of the chapter. I keep getting the following error when compiling, and have no idea where to go. I have an idea it might have to do with the linker flags, but I don't know what flag to add and where...
Here's the error:
Undefined symbols for architecture x86_64:
"Fl_JPEG_Image::Fl_JPEG_Image(char const*)", referenced from:
Graph_lib::Image::Image(Point, String, Graph_lib::Suffix::Encoding) in Graph.o
"Fl_GIF_Image::Fl_GIF_Image(char const*)", referenced from:
Graph_lib::Image::Image(Point, String, Graph_lib::Suffix::Encoding) in Graph.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
