[Insight-users] compile problem: vnl object files not linked in!

[Luis Ibanez]

Hi Zach

Can you please post your CMakeCache.txt
file to the list ?

Note that with "nm" you can demangle C++
names by using the option "-C" or its
equivalent "--demangle".

Before building with shared libraries and
wrapping ON, did you performed a build
without wrapping in this same binary directory ?

if yes, did you used static libraries in this
occasion ?

Please let us know,


    Thanks


      Luis
