[IGSTK-Users] help on itk 3.20.1 vs2008 compilation needed

[Özgür Güler]

Hi Aiden,

when I run following simple CMakeLists.txt

----CMakeLists.txt
cmake_minimum_required(VERSION 2.6)

set(VXL_SIZEOF_SIZE_T 7)
MATH(EXPR VXL_ADDRESS_BITS 8*${VXL_SIZEOF_SIZE_T} )
message(${VXL_ADDRESS_BITS})
----

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

The error you get is reproducible if you comment the line where I set
VXL_SIZEOF_SIZE_T  to 7.

In ITKs CMakeLists.txt this means that this variable is not set, which
causes the strange error message.
ITK tries to set this variable one line above MATH(.... with

check_type_size(size_t  VXL_SIZEOF_SIZE_T)

this CMake command should set the variable VXL_SIZEOF_SIZE_T with 4
(byte) or 8 (byte)
it seems that this command does not set this variable.

the following code snippet gives on my Laptop 32 (CMake 2.8, CMake 2.6)

INCLUDE (${CMAKE_ROOT}/Modules/CheckTypeSize.cmake)
#set(VXL_SIZEOF_SIZE_T 7)
CHECK_TYPE_SIZE(size_t  VXL_SIZEOF_SIZE_T)
MATH(EXPR VXL_ADDRESS_BITS 8*${VXL_SIZEOF_SIZE_T} )
message(${VXL_ADDRESS_BITS})

could you try that and post the result?

Best,
Özgür
