[vtkusers] problems building simple executable

[Robert S Laramee]

Dear Fellow VTK Users,

i'm trying to build a simple 
exectuable here, that is, i'm 
trying to convert:

VTK/Examples/Rendering/TCL/CADPart.tcl

to C++.  i'm having a little trouble
getting started.  i've included the
lines:

#include "vtkSTLReader.h"
...
  vtkSTLReader *part = vtkSTLReader::New();

It looks like there is no problem
building the object file, BobsApp.o,
however, it looks like there's a linking
problem, i.e., i get this error message:

[larameer at lnxc25 Cxx]$ make
Building object file BobsApp.o...
Building executable ./BobsApp...
/home/larameer/evaluation/vtk/vtk-src-unix/bin/libvtkIO.a(vtkSTLReader.o): In 
function `vtkSTLReader::CreateDefaultLocator(void)':
vtkSTLReader.o(.text+0x1bec): undefined reference to 
`vtkMergePoints::New(void)'
/home/larameer/evaluation/vtk/vtk-src-unix/bin/libvtkIO.a(vtkSTLReader.o): In 
function `vtkByteSwap::Swap4LE(float *)':
vtkSTLReader.o(.vtkByteSwap::gnu.linkonce.t.Swap4LE(float *)+0xe): undefined 
reference to `vtkByteSwap::Swap4LE(char *)'
/home/larameer/evaluation/vtk/vtk-src-unix/bin/libvtkIO.a(vtkSTLReader.o): In 
function `vtkByteSwap::Swap4LE(unsigned long *)':
vtkSTLReader.o(.vtkByteSwap::gnu.linkonce.t.Swap4LE(unsigned long *)+0xe): 
undefined reference to `vtkByteSwap::Swap4LE(char *)'
collect2: ld returned 1 exit status
make[1]: *** [BobsApp] Error 1
make[1]: *** Waiting for unfinished jobs....
make: *** [default_target] Error 2

Any ideas what the problem is?
i don't understand this because i've included
-lvtkIO into the linking.  My Makefile looks like 
the following.

#---------------------------------------------------------
# executable
#

./BobsApp: $(BobsApp_SRC_OBJS) $(BobsApp_DEPEND_LIBS)
	echo "Building executable ./BobsApp..."
	c++ \
	-I/usr/X11R6/include \
	-fPIC  $(BobsApp_SRC_OBJS) \
	-o ./BobsApp -rdynamic \
	-L/home/larameer/evaluation/vtk/vtk-src-unix/bin \
	-L. \
	-L/usr/X11R6/lib \
	-lvtkRendering \
	-lvtkGraphics \
	-lvtkImaging \
	-lvtkFiltering \
	-lvtkCommon \
	-lpthread \
	-lvtkIO \
	-ldl -lm -lSM -lICE -lSM -lICE -lX11 -lXext -lX11 -lXext -lvtkftgl -lGLU 
-lGL -lvtkfreetype -lXt -lSM -lICE -lX11 -lXext 
-Wl,-rpath,/home/larameer/evaluation/vtk/vtk-src-unix/bin:.:/usr/X11R6/lib 

Any feedback is most appreciated.

-cheers, bob
