Can anybody help to take a look? Thank you ...

Is there a reason you're not using the version in the repo? https://packages.ubuntu.com/jammy/exuberant-ctags


Browsing the changelog there is this:

* d/p/use-conventional-unused-marker.patch: Fix FTBFS against glibc 2.34

FTBFS is Failure To Build From Source.


Then at the top of the patch file use-conventional-unused-marker.patch:

The `__unused` macro has been used on Linux systems for this exact
purpose for ages. On the other hand, using the non-standard __unused__
breaks the build when compiling against glibc 2.34, as they use this
identifier internally.

So if you need to build exuberant-ctags it seems you will need to patch or modify the source.
