[Cmake] Re: [vtkusers] Error while building VTK 4.2.1 with CMake on Linux

[Joseph Barraud]

Hi,

Thanks for your answer.
I am using the latest version of Cmake (1.6.5). My purpose is to instal ITK 
with all the available options and demonstration applications. So I started 
with the installation of Cmake, then GCC_XML, Cable and FLTK (with the 
options shared libraries and threads activated). So I am at the "VTK 
stage". Everything worked fine so far (I hope so).

To run the process, I have "untared" the source file, then I made a 
directory vtk-build. I launched ccmake from this directory with:

ccmake ../VTK-4.2.1

The error occurs before the display of all the options in ccmake.
I have the latest Mandrake (gcc 3.2.2) and I have installed almost 
everything concerning development. I do have pthread.h in /usr/include and 
a number of files called thread-something in various places. I don't 
understand what's wrong with this pthread_create that seems to be a very 
basic function.

Joseph.
