Hi Charlie,
Welcome to ITK !
The errors that you are getting are due to FLTK.
We have tried to stick with a pretty stable
version of FLTK instead of using the latest one.
The recomended version of FLTK to use with
ITK examples is version 1.0.11.
The reason for the error messages in your build
is that starting with version 1.1 FLTK divided
its library in two libraries. One with the
tradicional widgets (fltk.lib) and a second
library (fltkgl.lib) with OpenGL related
widgets (like the Fl_Gl_Window for example).
FLTK version 1.0.11 used a single library: "fltk.lib".
Our CMake projects are configured to link with the
single "fltk.lib" of version 1.0.11 and do not include
at all the "fltkgl.lib" file.
The result is that when you install version 1.1, all
the OpenGL related widgets are missing at link
time because ITK project doesn't try to link with
fltkgl.lib. Those are the "unresolved external symbol"
messages that you are getting.
Other people have encounter this problem before
and they have adapted the CMakeList.txt files to
be compatible with both versions of FLTK or at least
to run with FLTK 1.1.
Probably the person who knows better how to do it
is Julien Jomier at UNC (he could probably give you
new CMakeList.txt files).
If you are anxious for getting ITK running
(and I bet you are :-)
Here are two quick solutions:
1) Download FLTK 1.0.11, build it, and reconfigure
ITK for using this version instead of the newest 1.1
(it will be quite fast since fltk is very compact)
or
2) In Project settings, go to the tab "Link" and add
fltkgl.lib to the list of libraries to link with.
This second option is not that good because you
will have to do it in *every* project that needs
the library.
Note that ITK itself does not require FLTK at all.
The only reason why FLTK is used is to provide some
examples of who to write applications that interface
a GUI with ITK.
We look forward to migrate the examples to FLTK 1.1,
since this version have some new interesting
functionalities like the support for "themes" that
make desktop applications look uniform.
Please let us know if you encounter any other
problem
Thanks
Luis
