<DIV>Hi,</DIV> <DIV> </DIV> <DIV>- You are right Julien: </DIV> <DIV>#define USE_FFTWD 1</DIV> <DIV>#include "itkFFTWRealToComplexConjugateImageFilter.h" removes the error that FFTWRealToConjugateComplexImageFilter is not a member of ITK. </DIV> <DIV> </DIV> <DIV>However, it is still not simple for me. Now, I have this kind of linking errors: </DIV> <DIV> </DIV> <DIV><STRONG><EM>"error LNK2019: symbole externe non résolu _fftw_destroy_plan référencé for</EM></STRONG></DIV> <DIV><FONT face="Courier New" size=2> <div><STRONG><EM>fftw_destroy_plan</EM></STRONG></div> <div><STRONG><EM>fftwf_destroy_plan</EM></STRONG></div> <div><STRONG><EM>fftw_execute</EM></STRONG></div> <div><STRONG><EM>fftw_plan_dft_r2c</EM></STRONG></div><FONT face="Courier New" size=2> <div><STRONG><EM>fftw_plan_dft_r2c_1d</EM></STRONG></div> <div><STRONG><EM>fftw_plan_dft_r2c_2d</EM></STRONG></div> <div></FONT><STRONG><EM>fftw_plan_dft_r2c_3d"</EM></STRONG></div>
<div><STRONG><EM></EM></STRONG> </div> <div>I believe that, maybe, <STRONG>ITK fftw librairies have not been built</STRONG>. Are there some ITK fftw librairies to build? Or do I have just to mention where are fftw.h and fftwd.lib as configuring ITK with CMake? As looking at FindFFTW.cmake, I find words about <STRONG>"libfftw.a-->double, libfftwf.a-->float":</STRONG> are there the names of ITK librairies for FFTW? If so, I made a search for these files in my ITK bin directory, and I didn't find them..... </div> <div> </div> <div>Isabelle</div> <div><EM></EM> </div> <div><EM> </div></EM> <div> </div> <div> </div></FONT><BR><B><I>Julien Jomier <jjomier@cs.unc.edu></I></B> a écrit :</DIV> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid">Isabelle,<BR><BR>you need to add:<BR><BR>#define USE_FFTWD 1<BR><BR>before including itkFFTWRealToComplexConjugateImageFilter.h in your
