This isn't a Free Pascal issue, this is a "welcome to Linux" issue.
Your code, or code that gets included in your software either by
Lazarus
or Free Pascal as part of their respective libraries, uses
functionality
that are only available in glibc 2.34 or newer. It won't work on Debian
11, that shipped with glibc 2.31.
Without knowing more about what your project tries to do, it's not
really
possible to tell, if there are any easy solutions to get around this,
apart from upgrading the target system...
...or compiling on the lowest version you intend to support, or creating
programs not using libc (which is possible with FPC even when targetting
Linux, but with limitations which make this theoretical option
impossible for Lazarus applications).
