Hi *,

according to https://pcre.org/, the pcre library version that SWIG is currently using is deprecated. Quote (emphasis added):

current version, PCRE2, released in 2015, is now at version 10.39.
The older, but still widely deployed PCRE library, originally released in 1997, is at version 8.45. This version of PCRE is now at end of life, and is no longer being actively maintained. Version 8.45 is expected to be the final release of the older PCRE library, and new projects should use PCRE2 instead.

This has been reported in Debian as https://bugs.debian.org/999948. Debian is planning to remove the old pcre from Debian for the bookworm release, but swig has a build dependency on it.

I intend to create a pull request to update the pcre dependency, but won't stop anybody else to work on this ;-)

Greetings, Torsten
