[Insight-users] FLTK and ITK on Mac OS X

[Phillip Cheng]

Hello,

I'm having some problems using some of the FLTK applications in 
InsightApplications under MacOS 10.2.4.

A number of applications such as MetaImageViewer and ImageRegistration 
build and run without error, but for some reason I cannot bring the 
windows into focus.  Interestingly, individual window widgets such as 
buttons and drop lists are responsive, but the window itself is not.  
Because the windows do not have focus, keyboard events are not 
received.  For instance, I can load an image in MetaImageViewer and a 
crosshair appears on mouse-clicks, but I cannot move between slices 
with the keyboard.

I am using fltk-1.1.3 and Apple's X11 0.2.  I should also note that I 
can run fluid and the applications in the fltk/test directory without 
any window focus problems.

Another problem is that the InsightApplications build chokes on 
AnisotropicDiffusionFltkGui:

Building executable AnisotropicDiffusionFltkGui2D...
ld: Undefined symbols:
Fl::error
make[3]: *** [AnisotropicDiffusionFltkGui2D] Error 1
make[2]: *** [default_target] Error 2
make[1]: *** [default_target_AnisotropicDiffusionFltkGui] Error 2
make: *** [default_target] Error 2

I'm not very familiar with FLTK, so I hope someone out there can help!

Thanks,

Phillip
