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

[Luis Ibanez]

Hi Phillip,

The Mac seems to need an additional setup for GUI applications.

You have to run a command like the following:

        /Developer/Tools/Rez Carbon.r -o MyProgram

If this doesn't give you the expected result, you may want to try
this second line that takes advantage of a default configuration
file provided by FLTK for the Mac:


/Developer/Tools/Rez Carbon.r /path-to-fltk/include/FL/mac.r -o
MyProgram


In both cases, please replace "MyProgram" whith the full path
to the executable of the program that you want to configure.

-------

This configuration can be done automatically by CMake if you
add the following lines to your CMakeLists.txt file. (again
replacing "MyProgram" with the real name of your executable).



ADD_EXECUTABLE(MyProgram ${MyProgram_SRCS})

IF(APPLE)
   FIND_PROGRAM(ITK_APPLE_RESOURCE Rez /Developer/Tools)
   IF(ITK_APPLE_RESOURCE)
     ADD_CUSTOM_COMMAND(
       SOURCE MyProgram
       COMMAND ${ITK_APPLE_RESOURCE}
       ARGS Carbon.r -o ${EXECUTABLE_OUTPUT_PATH}/MyProgram
       TARGET VolView
       )
   ENDIF(ITK_APPLE_RESOURCE)
ENDIF(APPLE)

-------

Please let us know if you encounter further problems,


Thanks


Luis
