[vtkusers] Getting Started Questions

[Labitt, Bruce]

I originally used ccmake and set "t" for the advanced view.  I did not
use RPATH originally.  In ccmake I set enabling python.

BUILD_TESTING is on.  I just did a make test and found that most tests
failed.  Umm, 916 out of 952 tests failed!

I just realized that I built vtk BEFORE I installed the ATI3D drivers.
That means I did not have "opengl" stuff installed.  So, do I need to
rebuild vtk?  I presume yes.

If I need to rebuild, then what do I do?  

make clean ? to uninstall everything

Then delete the contents of /VTK-build
and execute
[VTK-build]$ env CC=/usr/bin/gcc CXX=/usr/bin/g++ ccmake ../VTK

This is because I want to do a out-of-source build.

Does that sound right?  /VTK has the original files, and /VTKData the
data files.

Directory Structure
/home/me
/home/me/VTK	 ==> unmolested extracted files
/home/me/VTK-build ==> where I want stuff to be built
/home/me/VTKData	 ==> unmolested data files

Thanks

Couple ideas, but they may be way off for Linux.
   First, use "ccmake" to run the "gui" version of cmake. After that  
launches press the "t" key to get the advanced view. Scroll down the  
list and look for VTK_USE_RPATH (I think that is it) and turn that ON.  
This allows running VTK apps from the build directory but will stop  
any type of actual "install" of vtk. This may solve the library  
loading issues.

    Still in ccmake, there is an option to "BUILD_TESTING". Turn this  
on or make sure it was ON. Type "c" to configure again. Type "g" to  
generate new makefiles and exit ccmake.
   Recompile vtk. If you have a multi-core/multi-processor system use  
"make -j2" to help speed up the recompile.
   After the compilation reaches 100% you can do a "make test" which  
will run all the tests and report any errors. Simply watch the output  
for any tests that fail. If they all pass then you have a good build.

Hope some of that helps
