[vtk-developers] build errors with libvtkCommon.so.4.5

[tom fogal]

It seems like I didn't fully explain the issue in my initial message.
Sorry, hopefully this will clarify.

I assume you mean "ON" here, because I've just installed (see below)
without setting this environment variable.

I have just checked, this works appropriately.

I didn't explain this properly; the reason I wrote the original mail
was because the following did not work:

$ mkdir cvs_build_vtk
$ cd cvs_build_vtk
$ ccmake ../VTK
  # setup; note VTK_USE_RPATH is ON
$ make
$ sudo make install
  # bang head against wall for being dumb about VTK_USE_RPATH
$ ccmake ../VTK  
  # set VTK_USE_RPATH to OFF
$ rm bin/*
$ make
$ sudo make install

The second 'sudo make install' still failed with the same error.  I got
the impression from the error message that this was all I needed to do,
but I've yet to get it to work without 'rm -fr cvs_build_vtk'-ing and
restarting from scratch, ensuring VTK_USE_RPATH was OFF the *first*
time.

I was under the impression that removing everything in the bin/
directory should work.  Maybe I am just not following the appropriate
procedure?

Okay, I agree with the logic that CVS users should be smarter.
Should've have paid closer attention to that thread...  Sorry.
