I would suggest going outside the IDE and play around with those last
two compile + link lines in a terminal window until you get it to work,
then tweak your IDE to use the correct commands.
First, I'd suggest removing the -fexceptions from your compile line.
That might make the build different enough from the fltk lib's build
to cause link issues.
Also, as an aside, I'd suggest trying an absolute path to the libfltk.a
file instead of using the -L/-lfltk combo, eg:
OLD: mingw32-g++.exe -o bin\Debug\test.exe obj\Debug\main.o
-LC:\Users\Svalorzen\Documents\Projects\fltk-1.3.0\lib -mwindows -lfltk -lole32
-luuid -lcomctl32
NEW: mingw32-g++.exe -o bin\Debug\test.exe obj\Debug\main.o -mwindows
C:\Users\Svalorzen\Documents\Projects\fltk-1.3.0\lib\libfltk.a -lole32 -luuid
-lcomctl32
This seems to ensure a static link against the .a (as opposed to the
.so/.dll)
