[vtkusers] Compilation problems...

[Tuhin Sinha]

Hello everyone,

  I have two specific compilation errors that I was wondering about.

  (1)  Has anyone gotten the nightly tree to compile with the GNU 3.2 compiler 
collection with processor specific optimizations enabled?  I get as far as 
"vtkImageEuclideanDistance" and then I get compiler errors.  The error asks 
me to submit a bug report to the GCC developers, but I wanted to make sure I 
was doing things right.  My C(XX) flags in CMake were: "-O3 
-march=pentium{3|4} -fomit-frame-pointer".  I tried this configuration on a 
PIII 900 and a PIV 2.4, both choke at vtkImageEuclideanDistance (running 
Debian Testing, and Gentoo 1.4_rc1).  Compiling without the 
"-march=pentium{3|4}" works just fine on both platforms.
  
  (2) I can't get last night's source tree to compile.  Linking "vtk" stalls 
with the following errors:

/home/sinhatk/VTK/bin/libvtkRendering.so: undefined reference to `vtable for 
vtkXTextMapper'
/home/sinhatk/VTK/bin/libvtkRendering.so: undefined reference to 
`vtkXRenderWindowInteractor::New()'

/home/sinhatk/VTK/bin/libvtkRendering.so: undefined reference to 
`vtkXTextMapper::CollectRevisions(std::basic_ostream<char,

/home/sinhatk/VTK/bin/libvtkRendering.so: undefined reference to 
`vtkXTextMapper::PrintSelf(std::basic_ostream<char, std::char_traits<char> 
>&, vtkIndent)'

  Compiled with C(XX) flags: "-O3 -march=i686 -fomit-frame-pointer" using 
gcc3.0.  Is there something I'm doing wrong?  Thanks in advance for your 
help.
