[Insight-users] Linking errors with ITK+WTL - help please

[Frank Gao]

Hi Luis,

Thanks for the reply. I was able to get it work by searching some old posts.
The reason seems to be that I did not completely configure the project with
options found in vcl/vnl modules. I opened the ITK solution and coped the
options from there, and then get it work. I was using CMAKE, but I am pretty
new to this. Not sure how I can make sure to get options of VCL. I had
similar problem with another GUI tool the other day. It seems people tend to
have trouble with vcl and vnl.

Thanks again,

Frank

Hi Frank,

You seem to be making the common mistake of mixing compilation modes.

You probably built ITK for "Debug" and your application for "Release" ,
or the other way around.

Please make sure that you use the *EXACT* same compilation mode for
all the components of you application. That will include ITK, VTK,
and any other library that you may be combining.

If you were using CMake in order to configure your project, you
will not be having any of these problems.


    Regards,


       Luis
