[vtkusers] Problem building Activiz.NET wrappers

Tue Mar 1 10:08:59 EST 2011

Hey Mathieu,

I finally got it to work after having overlooked that Kitware supplies a public key in the root directory of both mummy/ and activizdotnet/. So, the way it's set up by default the dlls get delay-signed by this public key. The CMakeLists.txt files are set up to see whether you've set a value for AVDN_SNKEYFILE, and if not, it loads the Kitware public one and uses that:

# If a real strong name signing keyfile has not been predefined,
# then use the public key file in the source tree to /delaysign
# .NET assemblies...
#
IF(NOT DEFINED AVDN_SNKEYFILE)
  GET_FILENAME_COMPONENT(AVDN_SNKEYFILE "${CMAKE_CURRENT_SOURCE_DIR}/Kitware.VTK.pub.snk" ABSOLUTE)
ENDIF(NOT DEFINED AVDN_SNKEYFILE)
MESSAGE(STATUS "AVDN_SNKEYFILE='${AVDN_SNKEYFILE}'")

I generated my own keypair by running (in a Windows SDK v7.0 CMD Shell):

sn -k EMonsonVTKKeyPair.snk

and placed a copy of that file in the root source directory of both mummy and activizdotnet. For now I just added this section above the former one in the CMakeLists.txt files:

# Defining own keypair here...
GET_FILENAME_COMPONENT(AVDN_SNKEYFILE "${CMAKE_CURRENT_SOURCE_DIR}/EMonsonVTKKeyPair.snk" ABSOLUTE)

As far as I can tell it's working now. I didn't do extensive testing, but I was able to run one of the examples that wouldn't run before. 

I think it would be better to change the CMakeLists.txt files so that there was a real CMake option for setting that AVDN_SNKEYFILE variable during config – maybe that will get changed sometime... It would also be nice to have a real option, if testing is turned off, for not converting the Tcl tests.

Talk to you later,
-Eric

It looks like they must do it after the dlls are built, maybe with the Assembly Linker, rather than as part of the build process since the csharp AssemblyInfo.cs files don't contain an assembly key file attribute. It seems like it could be made part of the CMake setup to point to the key file and then have it automatically inserted into the correct spots so the assemblies get signed during the build. (But, I barely know what I'm talking about, so don't put too much weight on this yet... :)

I think the only non-default settings I used were turning ON BUILD_SHARED_LIBS and VTK_USE_PARALLEL (the latter I only figured out when activizdotnet needed VPIC.dll and couldn't find it -- someone should make a note on the instructions page that that VTK_USE_PARALLEL should be ON) and turned OFF BUILD_TESTING and BUILD_EXAMPLES. Builds of gccxml and mummy went fine.
