Re: [Insight-users] Compile error with mingw

[Tomáš Kazmar]

Hi Nic,

  it seems that building ITK with mingw is somehow broken
by now. I have similar setup ITK 2.8.0, gcc 3.4.2, runtime 3.9,
w32api 3.6, mingw-makefiles and I get exactly the same error.

I found a workaround which is not elegant but works. Because
only symbols from SmartPointerForwardReference are missing,
I include itkSmartPointerForwardReference.txx from every
executable target as it is advised in the header file
itkSmartPointerForwardReference.h.


Question is why this linking error happens at all because all
relevant symbols are in libITKCommon.dll (according to
"nm libITKCommon.dll") which is included in linking. It seems
that explicitly for this purpose there is a
itkSmartPointerForwardReferenceProcessObject.cxx file which
is added to list of sources used to create that dll.

If anybody finds out what causes it, please let me know. Until
then we can use that ugly workaround.


Regards,
Tomas
