[Insight-users] cmake errors

[Julien Jomier]

Hi Tina,

This is perfectly normal.
Basically, CMake tries to compile sample programs to determine the optimal
configuration (compiler flags, etc...) for ITK depending on your platform
and environment.
The file you are looking at (CmakeError.log) contains the results of the
TryCompile() command used by CMake when the compilation of these sample
programs fails, which is a normal behavior. For instance, CMake tries to see
if "pthread_create" exists and because the compilation fails, it determines
that it does not on your platform.

That said, did you sucessfully compiled ITK on your linux box?

hope that helps,

Julien
