GLIBC problem with cqrlog

[OH1KH]

This is not directly an issue, but warning as I do not know how packages are build.

At the moment Fedora 35 does have GLIBC_2.34 update. Now, when I compile ready build binary files with Fedora35 I have received reports that they do not run any more in older Fedoras, or Debian/Ubuntu variants.
When starting Cqrlog compiled with F35 error "cqrlog: /usr/lib/libc.so.6: version `GLIBC_2.34' not found (required by cqrlog)" appears unless the system is F35 (or equal with same GLIBC_2.34 update, I think).

If I compile binary file with older Mint20, that is not updated at all, that binary will run ok as before. It runs ok also in Ferdora 35 with GLIBC_2.34 updated.

This affects also for QT5 version.

So it is now good to know that if a package holding cqrlog binary is build with system having `GLIBC_2.34' it may not run any more with systems having older GLIBC that may cause problems for many users.
