<DIV>Hi again,</DIV>
<DIV> </DIV>
<DIV>I am still trying to use FFTW in my project. </DIV>
<DIV> </DIV>
<DIV>- First, I thought it was because I didn't update my ITK version. Now, I installed the new release ITK2_2. ITK2_2's configuration, enabling USE_FFTWD and USE_FFTWF, is fine and the building, under visual c++, works without any problem. </DIV>
<DIV> </DIV>
<DIV>- Then, I want to configure my own project using FFTW with CMake. CMake still gives this error: FFTW_DIR should contain the file FFTWConfig.cmake, which I don't have. </DIV>
<DIV> </DIV>
<DIV>- As adviced, I tried to install FFTW3 independantly of ITK. However, it seems that <STRONG>Microsoft Visual C++ version 6.0 is buggy</STRONG>: <STRONG>no one successed to build fftw librairies with MSVC 6.0</STRONG> and the compiler of MSVC 6.0 can't call fftw librairies. </DIV>
<DIV> </DIV>
