Ok, stupid thing... I forgot to enable the ITK_USE_GPU feature when
compiling ITK 4.2. <br>
<br>
Thank you ! <br>

Here is my CMakeLists: <br>

2.8.5)<br>
project (fMRI)<br>
<br>
#set (CMAKE_VERBOSE_MAKEFILE ON)<br>
set(CMAKE_CXX_FLAGS "-g -Wall")<br>
<br>
if(COMMAND cmake_policy)<br>
cmake_policy(SET CMP0003 NEW)<br>
endif(COMMAND cmake_policy)<br>
<br>
# Find ITK.<br>
FIND_PACKAGE(ITK REQUIRED)<br>
IF(ITK_FOUND)<br>
INCLUDE(${ITK_USE_FILE})<br>
ENDIF(ITK_FOUND)<br>
<br>
add_executable(ReadDCMWriteNii niftihandler.cpp main.cxx )<br>
target_link_libraries(ReadDCMWriteNii ${ITK_LIBRARIES})</big><br>
</small></small></blockquote>
Should be OK right ? Seems like I'm not linking well something...
<br>

Dear all,<br>
<br>
I am trying to run the following sample code with ITK 4.2 in
order to <br>
perform a GPU-based mean filter:<br>
<br>
typedef
itk::GPUMeanImageFilter<ImageType,ImageType> filterType;<br>
filterType::Pointer blurFilter = filterType::New();<br>
blurFilter->SetInput(handler.getOutput());<br>
blurFilter->SetRadius(2);<br>
blurFilter->Update();<br>
<br>
<br>
And i get the following errors from the linker (compilation is
fine):<br>
<br>
CMakeFiles/ReadDCMWriteNii.dir/main.cxx.o: In function<br>
`itk::GPUKernelManager::New()':<br>
/usr/local/include/ITK-4.2/itkGPUKernelManager.h:60:

undefined<br>
reference to `itk::GPUKernelManager::LaunchKernel(int, int,

<br>
I don't see the error ? Seems like a bad declaration in the
header <br>
itkGPUKernelManager.h but I didn't find it... Everythinh is
well <br>
included in my code though. Anybody got an idea ?<br>
<br>
Thank you !<br>
<br>
Best regards,<br>
