Re: [wxVTK] terrible memory leak problems with using vtk on wxwidgets

[Mathieu M. <mat...@gm...>]

Hi Senthil,

  You should really read:

http://www.catb.org/~esr/faqs/smart-questions.html

  So I am going to guess since you are using Visual Leak that your are
on Win32. If you are on Win32, you may be suffering from the well know
issue with MFC:

http://www.vtk.org/pipermail/vtkusers/2007-May/090968.html

False memory leak reports are caused by VTK dlls loading *before* MFC dlls.
You have to use the linker's /delayload flag to avoid this issue.

The /delayload flag should be correct by default in the MFC examples if you
are using CVS VTK... If you are using a previous version of VTK (5.0 or
earlier) then you will have to figure out a way to link with that flag.

See the CVS version of files in VTK/GUISupport/MFC for details. Or grep the
VTK source tree for "DELAYLOAD"



Let us know if this solve your issue

Thanks
