&gt;Hi&nbsp;Aiden,

&gt;

&gt;when&nbsp;I&nbsp;run&nbsp;following&nbsp;simple&nbsp;CMakeLists.txt

&gt;

&gt;----CMakeLists.txt

&gt;cmake_minimum_required(VERSION&nbsp;2.6)

&gt;

&gt;set(VXL_SIZEOF_SIZE_T&nbsp;7)

&gt;MATH(EXPR&nbsp;VXL_ADDRESS_BITS&nbsp;8*${VXL_SIZEOF_SIZE_T}&nbsp;)

&gt;message(${VXL_ADDRESS_BITS})

&gt;----

&gt;

&gt;with&nbsp;CMake&nbsp;2.8&nbsp;and&nbsp;2.6&nbsp;it&nbsp;works&nbsp;fine&nbsp;and&nbsp;I&nbsp;get&nbsp;the&nbsp;result&nbsp;56&nbsp;as&nbsp;output.

&gt;

&gt;The&nbsp;error&nbsp;you&nbsp;get&nbsp;is&nbsp;reproducible&nbsp;if&nbsp;you&nbsp;comment&nbsp;the&nbsp;line&nbsp;where&nbsp;I&nbsp;set

&gt;VXL_SIZEOF_SIZE_T&nbsp;&nbsp;to&nbsp;7.

&gt;

&gt;In&nbsp;ITKs&nbsp;CMakeLists.txt&nbsp;this&nbsp;means&nbsp;that&nbsp;this&nbsp;variable&nbsp;is&nbsp;not&nbsp;set,&nbsp;which

&gt;causes&nbsp;the&nbsp;strange&nbsp;error&nbsp;message.

&gt;ITK&nbsp;tries&nbsp;to&nbsp;set&nbsp;this&nbsp;variable&nbsp;one&nbsp;line&nbsp;above&nbsp;MATH(....&nbsp;with

&gt;

&gt;check_type_size(size_t&nbsp;&nbsp;VXL_SIZEOF_SIZE_T)

&gt;

&gt;this&nbsp;CMake&nbsp;command&nbsp;should&nbsp;set&nbsp;the&nbsp;variable&nbsp;VXL_SIZEOF_SIZE_T&nbsp;with&nbsp;4

&gt;(byte)&nbsp;or&nbsp;8&nbsp;(byte)

&gt;it&nbsp;seems&nbsp;that&nbsp;this&nbsp;command&nbsp;does&nbsp;not&nbsp;set&nbsp;this&nbsp;variable.

&gt;

&gt;the&nbsp;following&nbsp;code&nbsp;snippet&nbsp;gives&nbsp;on&nbsp;my&nbsp;Laptop&nbsp;32&nbsp;(CMake&nbsp;2.8,&nbsp;CMake&nbsp;2.6)

&gt;

&gt;INCLUDE&nbsp;(${CMAKE_ROOT}/Modules/CheckTypeSize.cmake)

&gt;#set(VXL_SIZEOF_SIZE_T&nbsp;7)

&gt;CHECK_TYPE_SIZE(size_t&nbsp;&nbsp;VXL_SIZEOF_SIZE_T)

&gt;MATH(EXPR&nbsp;VXL_ADDRESS_BITS&nbsp;8*${VXL_SIZEOF_SIZE_T}&nbsp;)

&gt;message(${VXL_ADDRESS_BITS})

&gt;

&gt;could&nbsp;you&nbsp;try&nbsp;that&nbsp;and&nbsp;post&nbsp;the&nbsp;result?

&gt;

&gt;Best,

&gt;Özgür

&gt;

&gt;&gt;&nbsp;Hi,

&gt;&gt;

&gt;&gt;&nbsp;May&nbsp;I&nbsp;ask&nbsp;for&nbsp;help&nbsp;on&nbsp;the&nbsp;compilation&nbsp;of&nbsp;itk&nbsp;3.20.1&nbsp;using&nbsp;vs2008?

&gt;&gt;

&gt;&gt;&nbsp;If&nbsp;I&nbsp;use&nbsp;cmake&nbsp;2.8.7,&nbsp;I&nbsp;got&nbsp;the&nbsp;same&nbsp;error&nbsp;when&nbsp;configuring:

&gt;&gt;

&gt;&gt;&nbsp;http://www.itk.org/pipermail/insight-users/2011-December/043132.html

&gt;&gt;

&gt;&gt;&nbsp;Then&nbsp;I&nbsp;switched&nbsp;to&nbsp;cmake&nbsp;2.6.4,&nbsp;turned&nbsp;off&nbsp;BUILD_TESTING&nbsp;and&nbsp;BUILD_EXAMPLE,

&gt;&gt;&nbsp;I&nbsp;got&nbsp;a&nbsp;similar&nbsp;warning,&nbsp;as&nbsp;attached.

&gt;&gt;

&gt;&gt;&nbsp;In&nbsp;the&nbsp;end,&nbsp;I&nbsp;got&nbsp;a&nbsp;message&nbsp;of&nbsp;error,&nbsp;but&nbsp;without&nbsp;any&nbsp;red&nbsp;line.&nbsp;The&nbsp;"OK"

&gt;&gt;&nbsp;button&nbsp;is&nbsp;grayed.&nbsp;I&nbsp;guess&nbsp;it&nbsp;is&nbsp;the&nbsp;same&nbsp;error&nbsp;with&nbsp;cmake&nbsp;2.8.7.&nbsp;I&nbsp;attached

&gt;&gt;&nbsp;the&nbsp;CMakeCache.txt,&nbsp;ITKBuildSettings.cmake,&nbsp;ITKConfig.cmake&nbsp;here.

&gt;&gt;

&gt;&gt;&nbsp;Thanks&nbsp;a&nbsp;lot&nbsp;for&nbsp;helping&nbsp;out.

&gt;&gt;

&gt;&gt;&nbsp;Regards,

&gt;&gt;&nbsp;Aiden

&gt;&gt;
