I start with a clean empty build tree. Since Apple do not support
gcc 4.5.2 (think they have moved to clang or something) I used Mac
Ports to buld and install gcc 4.5.2. I used gcc_select, a script
that manages all the symbolic links. So CMake finds gcc, g++ etc
in the appropriate locations. I get the same error with 2.8.4 as
follows:<br>
<br>
bricklemacho-imac-g5:VTK-Clean brickle$ cmake -version<br>
cmake version 2.8.4<br>
<br>
bricklemacho-imac-g5:VTK-Clean brickle$ cmake -G "Unix Makefiles"

How do you tell CMake to use gcc 4.5.2? (Is it in the PATH, do you
set CC and CXX env vars?)<br>
<br>
Does the same thing happen with CMake 2.8.4?<br>
<br>

I previously had compiled under GCC 4.2.1 but was required to
upgrade to<br>
GCC 4.5.2 to allow PCL (Point Cloud Library) compile. PCL has
a<br>
dependency on VTK for its visualizer.<br>
<br>
I am now trying to compile VTK on MacOS 10.6.7, GCC 4.5. Can
anyone<br>
help with the following error which occurs during the CMake
process:<br>
