Sorry, the code I linked above is based on a much earlier library which was a prototype of Kocherga. Please use this example instead:
kocherga-demo.tar.gz (27.9 MB)
I had to edit the sources manually before publishing but they should still be valid.
You are running a very old GCC. The demo attached here requires v7.3.
Why the code generator has failed is unclear; consider re-running with -v if the issue persists.
