cmake arch 64 issue

druk · 2010-05-26 02:46:09

It seems cmake in arch 64 does not set the internal variable CMAKE_SIZEOF_VOID_P. It works in arch 32. Can this be a problem with the pakage or with cmake?

[rtiago@zulu hummstrumm]$ cmake .
CMAKE_SIZEOF_VOID_P =
-- Configuring done
-- Generating done
-- Build files have been written to: /home/rtiago/games/hummstrumm

[rtiago@zulu hummstrumm]$ uname -s -r -v -m
Linux 2.6.33-ARCH #1 SMP PREEMPT Mon Apr 26 19:31:00 CEST 2010 x86_64

[rtiago@zulu hummstrumm]$ cmake --version
cmake version 2.8.1

In 32-bit works.
[rtiago@zulu hummstrumm]$ cmake .
CMAKE_SIZEOF_VOID_P = 4
-- Configuring done
-- Generating done
-- Build files have been written to: /home/rtiago/games/hummstrumm

Does anyone uses cmake in arch 64?

Can anyone test this on their systems? I would like to know if this is somewhat specific to my installation of its a bug in cmake.

Just follow this simple instructions.

Pacman -S cmake

create a CMakeLists.txt

project (test)
cmake_minimum_required (VERSION 2.6)
message("CMAKE_SIZEOF_VOID_P = ${CMAKE_SIZEOF_VOID_P}")

Run "cmake ." in the directory where CMakeLists is.

I really appreciate.

It works fine for me - and I do use cmake to build some other stuff on arch64

Thanks sr! This is something with my installation then.

There must have been some updates in the cmake package because running pacman -Su, has upgraded cmake but the version numbered stayed the same?!

[2010-05-27 18:19] starting full system upgrade
[2010-05-27 18:22] upgraded cmake (2.8.1-2 -> 2.8.1-2)

After doing the upgrade and clearing cmake cache, everything works as expected.
