Unable to run this repo

[pen9u1nlee]

Hello Dr Alexandru, I have some troubles in running this repo. My steps are listed below:

1. PALISADE v1.9.1 is installed globally.
2. CmakeLists.User.txt is copied to this repo's root directory and configured following the README in PALISADE.
3. Remote includes like #include "../../core/lib/math/matrix.cpp" in Plant.h are fixed locally with #include "matrix.cpp".

However errors occur upon making executables and there are some questions:

• Where is ckks.cpp which is included in ckks-impl.cpp? I didn't find it neither in PALISADE nor in this repo.
• I want to know whether I configure this repo in a proper way. E.g. in step 3, should I copy these head files into the PALISADE library?

Fantastic Data-driven Predictive Control work by the way :)

Hi!

• ckks.cpp is included in the PALISADE repository https://gitlab.com/palisade/palisade-development/-/tree/v1.9.1/src/pke/lib/scheme/ckks .
• I had the source files (data-driven-control.cpp, Plant.h, helper-control.h) in the src/pke/examples folder; I recall I had a problem with the CmakeLists.User.txt at the time and that's why I preferred to compile the examples folder.
• The modifications I highlight in matrix.cpp need to be made in the existing file at ../../core/lib/math/matrix.cpp, i.e., matrix.cpp should not be a local file. The same holds for the highlighted modifications for matrix.h, pubkey.h, cryptocontext.h, ckks.h, ckks-impl.cpp.

There are two things worth mentioning. First, in the repository here https://github.com/andreea-alexandru/swift-private-data-driven-control (but with the same description for running it), there is a better version of roughly the same problem. Second, there have been tremendous improvements in more recent PALISADE versions, both in terms of substantial low-level optimizations and user-friendliness. So I suggest that if you want to implement your own project, you use a newer version.

Hope this helps!
