[Insight-users] link issue

[Luis Ibanez]

Hi Delphine


The symbol

                      ifuShowText()

is defined in

    InsightApplications/Auxiliary/FltkImageViewer

in the files

             fltkUtils.*

 From your error message, it looks like you are building
this library as a Shared library, and since the declaration
of this function doesn't have the EXPORT, then the symbol
is not available for linking.

You can try building the library as a STATIC library
or you could add the EXPORT to the function (and probably
will have to add it for other functions too...)


Please let us know what you find....


    Thanks


       Luis
