Hello,
I have just downloaded the latest stable version of OpenCV (2.4.4) and tried to compile it. The compilation fails with the following messages:
<pre>

The command used for compilation is (from http://opencv.willowgarage.com/wiki/InstallGuide):
@cmake

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/Users/u/lib/opencv@
CMAKE_INSTALL_PREFIX=/Users/u/lib/opencv

with:
@$->

$-> cmake --version
cmake version 2.8.10@
2.8.10

and
<pre>$->

$-> g++ -v
