Hi all,

Compiling Exim 4.96 fails on Devuan 4.0 Chimaera (basically Debian but
without systemd).

Firstly it complained that I didn't have "pcre2.h" - which it has never
asked for before:

    /bin/sh ../scripts/Configure-os.h
    cc -DMACRO_PREDEF macro_predef.c
    In file included from macro_predef.c:12:
    exim.h:527:10: fatal error: pcre2.h: No such file or directory
      527 | #include <pcre2.h>
          |          ^~~~~~~~~
    compilation terminated.

so I did:

    root@relay1:/home/mike/exim-4.96# apt-cache search pcre2
    elpa-pcre2el - Emacs mode to convert between PCRE, Emacs and rx
regexp syntax
    libpcre2-16-0 - New Perl Compatible Regular Expression Library - 16
bit runtime files
    libpcre2-32-0 - New Perl Compatible Regular Expression Library - 32

    libpcre2-8-0 - New Perl Compatible Regular Expression Library- 8

    libpcre2-dev - New Perl Compatible Regular Expression Library -

    libpcre2-posix2 - New Perl Compatible Regular Expression Library -

    libpcre3 - Old Perl 5 Compatible Regular Expression Library -

    libpcre3-dev - Old Perl 5 Compatible Regular Expression Library -

    librust-grep-pcre2-dev - Use PCRE2 with the 'grep' crate - Rust

    librust-pcre2-dev - High level wrapper library for PCRE2 - Rust

    pcre2-utils - New Perl Compatible Regular Expression Library -

    root@relay1:/home/mike/exim-4.96#

and installed the bits I thought I needed:

    root@relay1:/home/mike/exim-4.96# apt-get install libpcre2-dev
libpcre2-posix2

Can't seem to find what's missing ... any ideas?
