Make launcher with extension module

park · November 13, 2023, 9:54am

Hi all

I am trying to create an application launcher with custom and built extionsion modules.
I would like the modules loaded in slicer already when the custom application is installed by launcher.

I found a similar topic [Customized application launchers] and there is an option for custom installers that can be built without modifying anything in Slicer source code, just by tuning CMake options.

As I understood :

the base slicer and all modules should be built already in the released version separately.
a .cmake file should be created or modified when building PACKAGE project in the CMakePredefinedTargets folder.

Could you let me know which .cmake file should be modified and can I get any examples of it?

This is my file list for cmake build .
The S dir is slicer source code and the left dirs are modules

If you have not done already, looking at this project may be helpful to understand the process:

… as well as these two companion posts published on the Kitware blog:

Thank you for your reply

If I modify the CMakeLists.txt of the SlicerCat or make changes to qCustomAppNameAppMainWindow.cxx, do I need to rebuild the entire project? If so, are there any ways to reduce the build time? Building once takes a considerable amount of time.

Yes, project-wide changes like the top level CMakeLists.txt can trigger a long rebuild. However since the default is shared libraries, once you have the structure set up changes to the implementation go more quickly since you can just rebuild the inner targets.

Hi pieper

Can you recommend an alternative method for creating a package, other than using Slicer Cat? The project has already progressed significantly, and it seems challenging to reconfigure it using Slicer Cat. Despite the challenges, is it still more efficient to use Slicer Cat and start over from the beginning? The functionality is already complete, but creating a package turns out to be more challenging than anticipated.

Building custom C++ packages that will run reliably on other computers is a big challenge and there are many things that can go wrong. SlicerCat leverages a lot of debugging that allows Slicer packages to build and run cross-platform. The only reliable options I know of to simplify the process are to narrow the target (e.g. only support one OS, but this only helps a bit) or write only in Python so you can use pre-build binaries.

Thank you Steve

jcfr&Steve could you check there is any thing worng my CmakeList.txt ?
The build was completed without error but I cannot find extension module like IGT, OpendIGTLink ,

Moreover, how could I use the modified Slicer source file that I worked on instead of the Slicer file obtained from Git?

Moreover, I really appriciate if you give me the example of CMakeList.txt you use.
