1. Am using the GNAT 2020 toolchain to compile software and as detailed above have successfully compiled other projects.
2. Running Debian Linux bullseye/testing on a 64 bit machine.

Any help would be much appreciated.

Deepest apologies for any time wasting. Investigated further and discovered an error in my ADA_INCLUDE_PATH variable and when set correctly it now compiles. Having trouble with the libadalang-tools part but given the above, I'm sure that's me. Again apologies for the time wasting.
