Hi all,
2nd follow-up.
- PCRE2 - Compatibility layer (PCRE1 + PCRE2) vs full migration
I have successfully built the current codebase using PCRE2 only on all the following platforms (see list below).
The oldest system tested was CentOS 7, and it builds fine. Note: CentOS 7 packages are no longer available on the standard RHEL repos, so an archive mirror must be used.
Next step: I will drop my compatibility branch and move to Roland's work.
Plan:
- Replace PCRE1 with PCRE2 (option 2)
- Use Roland's branch as the base going forward
- Cut a minor release, even if this could have been a major-release item
- Dcoument
- RRD1.9
Some patches have been applied, but they still need proper testing. There are quite a few compilation warnings. I have prepared a cleanup patch, but I will not apply it at this stage.
- MD5 warnings
Several systems now mark MD5 as deprecated, which generates warnings during compilation (notably on newer Linux distributions and macOS).
This does not currently break the build, but it impacts clean compilation on modern systems and should be addressed.
Summary: with the current patch set (still needs review), I successfully built: Both RRD and PCRE changes (as well as MD5 deprecation) have a direct impact on installing Xymon on newer systems.

- CMake build
Plan:
- Reproduce the current configure / make / make install workflow
- Keep both build systems in parallel for some time
CMake is not intended to replace the current build immediately. This will be a gradual transition.
