[vtkusers] C++ VTK app on OSX

[Sandor Heman]

Hi,

I'm new to both VTK and Mac OS X and recently compiled VTK (withous other
language bindings) successfully.
But now when I try to build the simple sphere example from the VTK website
(under "examples") I get the following error after I type "make":

>>>
c++ -O2 -Wall  -I/usr/local/vtk -I/usr/src/VTK/Contrib -I/usr/src/VTK/Common
-I/usr/src/VTK/Graphics -I/usr/src/VTK/Imaging -I/usr/src/VTK/Rendering
-I/usr/src/VTK/Filtering -I/usr/src/VTK/Patented -c sphere.cxx -o sphere.o
c++ sphere.o -L/usr/local/vtk/bin -lVTKImaging -lVTKGraphics -lVTKRendering
-lVTKFiltering -lVTKCommon -lpthread -o sphere
ld: /usr/lib/crt1.o illegal reference to symbol: __objcInit defined in
indirectly referenced dynamic library /usr/lib/libobjc.A.dylib
make: *** [sphere] Error 1

I am using gcc 3.1 with the following Makefile (sources are in /usr/src/VTK
and build dir is /usr/local/vtk) :


>>>
.SUFFIXES: .cxx

# Specify the name of the program you want created on this line:
TARGET = sphere

# Specify the objects that make up your program in this line:
OBJECTS = sphere.o

${TARGET}: ${OBJECTS}

# Compiler and linker definitions for the different libraries we need:

# The Visualization Toolkit (Vtk):

VTK_HOME      = /usr/src/VTK
VTK_INC       = -I/usr/local/vtk \
                -I${VTK_HOME}/Contrib \

# Compiler and linker flags:

CXX_FLAGS     = -O2 -Wall ${DEFINES} ${INCLUDES}

# Automatic generator rules:

.o:

# Other targets:

clean:
        $(RM) ${OBJECTS} $(TARGET)

If anybody knows how to solve this problem and what I am doing wrong that
help would be really appreciated.

Thanks in advance
