Hi,
the MitkDiffusionIO module is a "auto-load module" which *should* only
provide IO classes for diffusion related types. Such a module usually
does not export any symbols and hence does not have a public API.
Although you can technically link to it (by writing DEPENDS
MitkDiffusionIO) there are two issues:
1. The module usually does not have a public API
2. The module's runtime file (.so, .dll, .dylib) is located in a special
sub-directory which leads to runtime linker errors due to missing PATH
entries on Windows
In your case, the mitk::FiberBundleXMapper2D is not exported and hence
not public API. You might argue that it should be moved e.g. into the
MitkFiberTracking module and be exported for re-use. This is a decision
for our diffusion sub-group and you might want to discuss this in a
separate mail.
Best,
Sascha

Hi all,
I'm trying to extend mitk::FiberBundleXMapper2D to change its behavior.
To do so, I created my own class where I changed one of the virtual
method and added MitkDiffusionIO to my cmakelist
MITK_CREATE_MODULE( ImekaFiber
DEPENDS MitkDataTypesExt MitkDiffusionIO ...
PACKAGE_DEPENDS Qt4|QtCore
EXPORT_DEFINE IMEKAFIBER_EXPORT
)
Yes, I use IMEKAFIBER_EXPORT with my class.
The problem is, I have some external errors that I don't understand:
PeaksMapper2D.obj : error LNK2001: unresolved external symbol...
public: virtual class vtkProp * __cdecl
mitk::FiberBundleXMapper2D::GetVtkProp(class mitk::BaseRenderer *)
protected: __cdecl
mitk::FiberBundleXMapper2D::FiberBundleXMapper2D(void)
protected: virtual __cdecl
mitk::FiberBundleXMapper2D::~FiberBundleXMapper2D(void)
protected: virtual void __cdecl
mitk::FiberBundleXMapper2D::GenerateDataForRenderer(class
mitk::BaseRenderer *)
On another module, I use the MitkFiberTracking module and it works.
The only difference I can see is that MitkDiffusionIO has
"AUTOLOAD_WITH MitkCore" in its cmakelist. Is it possible to depend on
a module that uses autoload? Thank you for your time.
