Summary0005647: ITK with shared libs on does not compile under MinGW
DescriptionCurrent ITK does not compile because MinGW linker does not find some symbols correctly (SmartPointerForwardReference). It fails during linking step of itkTestDriver.exe.

Solution/hack to overcome this bug can be to include itkSmartPointerForwardReference.txx in the source code of every executable, like itkTestDriver.exe, examples or any user application.

The bug is triggered by BUILD_SHARED_LIBS=ON cmake option.

This bug was discussed many times on mailing list since December 2006:

Recently there were also two threads in developers mailing list:

[Insight-developers] SmartPointerForwardReference Compile error with mingw
[Insight-developers] Re: [Insight-users] Fixing bugs for ITK with MinGW

This seems as an important bit from the former:

# I think it was for some interaction between ProcessObject and
# DataObject. There is an explicit instantiation of
# SmartPointerForwardReference inside itkDataObject.cxx, but it is not
# dllexport-ed.

The patch was committed to CVS
http://www.itk.org/cgi-bin/viewcvs.cgi/Code/Common/CMakeLists.txt?root=Insight&sortby=date&r2=1.125&r1=1.124 [^]

and the previous attempt (that didn't work) was removed.

We need a build of ITK in MinGW with SHARED_LIBS on in order to test this.

Duplicate bug 6724 resolves the issue. An update to cmake 2.6.4 permits successful shared library builds on cygwin and mingw.
