Dear All,

I moved this question from my email to [insight-users@itk.org](mailto:insight-users@itk.org) to this forum as suggested by Dženan. The original content (sent to [insight-users@itk.org](mailto:insight-users@itk.org)) was copied below. Dženan asked whether I used CMake to configure the compiler for the read-image-file code.

I used the following CMake file and set ITK\_DIR in ccmake to /path/to/ITK-build-release with the same compilation setting as the compiler setting for building the ITK library with  
CMAKE\_CXX\_COMPILER /usr/lib64/ccache/c++  
CMAKE\_CXX\_FLAGS -std=c++11 -pthread  
CMAKE\_EXE\_LINKER\_FLAGS -pthread  
After configuring and generating using ccmake, I call ‘make’ to compile and build the code.

Would anyone know why I get this error or how could I fix this error?

Thank you very much for your time and help

Best regads,

Ja

#- CMake file  
cmake\_minimum\_required(VERSION 2.8)

project(read\_image)

find\_package(ITK REQUIRED)  
include(${ITK\_USE\_FILE})

add\_executable(test\_read\_image test\_read\_image.cxx)  
target\_link\_libraries(test\_read\_image ${ITK\_LIBRARIES})

#-Content in the original email

I have a problem compiling a simple read-image-file code below in Fedora, after I build ITK 4.12.1 from source code downloaded from the ITK website. I did not receive any error for compiling ITK. For compilation of ITK 4.12.1, I did not change the default CMake options of the ITK library, and the CMake options for compilation were set as

CMAKE\_CXX\_COMPILER /usr/lib64/ccache/c++  
CMAKE\_CXX\_FLAGS -std=c++11 -pthread  
CMAKE\_EXE\_LINKER\_FLAGS -pthread

The error, from compiling the read-image-file code below, was all “undefined reference to ‘vnl\_vector::~vnl\_vector()’” with some data types T including long long, short, unsigned char, etc. I attached the file containing the error (std::cerr from ‘make’ command for single-thread compilation) to this email.

// Code  
#include “itkImageFileReader.h”

int main()  
{  
typedef itk::Image\<float, 2\> ImageType;  
typedef itk::ImageFileReader ImageFileReaderType;  
ImageFileReaderType::Pointer reader = ImageFileReaderType::New();  
reader-\>SetFileName(“some\_image\_filename”);  
reader-\>Update();

ImageType::Pointer image = reader-\>GetOutput();

return EXIT\_SUCCESS;  
}

Here is the part of the error I got. I cannot put all the error in due to the character limit of the forum.

Your CMakeLists.txt looks normal, declaring a lower minimum version should not be a problem.

I had this problem compiling ITK 4.12 with CMake 2.8.12.2 on CentOS 6. It went away when I built ITK with CMake 3.6.1.

I successfully compiled and ran the read-image-file code after I used CMake 3 to configure both ITK and the code. Thank you very much, Philip and everyone.
