[vtkusers] Re: problems building simple executable

[Goodwin Lawlor]

Hi Robert,
How about using cmake with a simple CMakeLists.txt config file from here:
http://www.vtk.org/Wiki/VTK_FAQ#Writing_a_simple_CMakeLists.txt.
to build your make file for you.

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):

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):

vtkSTLReader.o(.vtkByteSwap::gnu.linkonce.t.Swap4LE(float *)+0xe): undefined

/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. \

-Wl,-rpath,/home/larameer/evaluation/vtk/vtk-src-unix/bin:.:/usr/X11R6/lib

Any feedback is most appreciated.

-cheers, bob
