[vtkusers] Undefined reference using CygWin+VTK+wxWidgets+wxVTK

[jonas]

I'm trying to compile the wxVTK package, but gets a linking error when linking
Sample.exe when running make. This is my configuration:

- VTK 4.4.2 compiled and installed in four different configurations (debug,
debug+static, release and release+static) in /usr/local/
- wxWidgets 2.6.3 alsp compiled and installed in four different configurations
(debug, debug+static, release and release+static) in /usr/local/
- ccmake version 2.2-patch 3
- All using the latest CygWin in WindowsXP

I get five (one for each sample in wxVTK) warnings when generating in ccmake:

Warning: Ignoring path found in link libraries for target: Sample, the path is :
/usr/local/lib. Expected a library name or full path to a library name.

It all compiles but when linking Sample.exe I get a lot of 'undefined reference'
(one of them is 'undefined reference to `wxClassInfo::Register()´).

I've tried forcing the linker flags to the output of `wx-config --libs´ with no
success:

CMAKE_EXE_LINKER_FLAGS:STRING=-L/usr/local/lib -lwx_msw_xrc-2.6 -lwx_msw_qa-2.6
-lwx_msw_html-2.6 -lwx_msw_adv-2.6 -lwx_msw_core-2.6 -lwx_base_xml-2.6
-lwx_base_net-2.6 -lwx_base-2.6

The only progress I could make was to add the linking info directly into
CMakeFiles/Sample.dir/build.make but this isn't nice coding:

bin/Sample.exe: CMakeFiles/Sample.dir/build.make
    @echo "Linking CXX executable bin/Sample.exe"
    $(CMAKE_COMMAND) -E remove -f bin/Sample.exe
    c++    -Wno-deprecated -mwin32  -L/usr/local/lib -lwx_msw_xrc-2.6
-lwx_msw_qa-2.6 -lwx_msw_html-2.6 -lwx_msw_adv-2.6 -lwx_msw_core-2.6
-lwx_base_xml-2.6 -lwx_base_net-2.6 -lwx_base-2.6  $(Sample_OBJECTS)
$(Sample_EXTERNAL_OBJECTS)  -o bin/Sample.exe  -L/cygdrive/c/apps/wxVTK/bin
-L/usr/lib/w32api -L/usr/local/lib/vtk -lvtkIO -lvtkHybrid -lvtkCommon
-lvtkGraphics -lvtkRendering -lcomctl32 -lrpcrt4 -lwsock32 -lopengl32 -lglu32
-lvtkGraphics -lvtkImaging -lvtkIO -lvtkFiltering -lvtkCommon -lpthread -lgdi32
-lm -lvtkDICOMParser -lvtkpng -lvtktiff -lvtkzlib -lvtkjpeg -lvtkexpat -lvtkftgl
-lvtkfreetype -lglu32 -lopengl32


So my final question is; how do i solve the linking problem to wxWidget?


This is the CMakeCache file in the wxVTK directory

# You can edit this file to change values found and used by cmake.
# If you do not want to change any of the values, simply exit the editor.
