mariadb-10.6: fails to run due to missing dependency on lzo2

[jasimon9]

With an assist from ChatGPT, I found this in iMac-tmp.log when attempting to start mariadb-10.6-server after a port migrate:

250410 14:52:34 mysqld_safe Starting mariadbd daemon with databases from /opt/local/var/db/mariadb-10.6
dyld[3693]: Library not loaded: /opt/local/lib/liblzo2.2.dylib
  Referenced from: <55E2626A-BC78-303A-A67F-90AD03518BBD> /opt/local/lib/mariadb-10.6/bin/mariadbd
  Reason: tried: '/opt/local/lib/liblzo2.2.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OS/opt/local/lib/liblzo2.2.dylib' (no such file), '/opt/local/lib/liblzo2.2.dylib' (no such file)
250410 14:52:34 mysqld_safe mysqld from pid file /opt/local/var/db/mariadb-10.6/Mac.lan.pid ended

ChatGPT suggested installing the lzo2 port. After doing that, mariadb-10.6-server ran correctly.

A few contributing factors:

1. During the port migrate, I answered "yes" to all cleanup prompts—this may have removed lzo2.

2. port reclaim might have removed it as well.

3. lzo2 is listed as requested in port echo installed requested, so its removal was unexpected.

Notably, sudo port load mariadb-10.6-server would succeed, but the daemon would silently fail shortly after startup.

It appears the MariaDB server binary links to liblzo2.2.dylib, but no corresponding depends_lib entry exists in the mariadb-10.6 Portfile. Suggest adding port:lzo2 as a dependency for both mariadb-10.6 and mariadb-10.6-server (and perhaps other versions, if affected).

The dependency would belong in mariadb-10.6 not mariadb-10.6-server.

lzo ought to be installed by default as a dependency of mariadb.10.6.
from a recent log :

Replying to BjarneDMat:

lzo ought to be installed by default as a dependency of mariadb.10.6.

mariadb-10.6 does not declare a dependency on lzo2:

% port deps mariadb-10.6
Full Name: mariadb-10.6 @10.6.21_1
Build Dependencies:   cmake, bison, pkgconfig
Library Dependencies: curl, judy, libxml2, ncurses, pcre2, tcp_wrappers, zlib, boost178, openssl3
Runtime Dependencies: mysql_select

If mariadb-10.6 links directly with lzo2, as the error message says, then mariadb-10.6 must directly declare that library dependency.

Yes, lzo2 might be somewhere else in the dependency chain already, but evidently only via a build dependency. (mariadb-10.6 has a build dependency on cmake which has a library dependency on libarchive which has a library dependency on lzo2.) If mariadb-10.6 is installed as a binary, then MacPorts will not install those build dependencies.

I'll look into updating the various mariadb ports and will add the lzo2 dependency as needed.

Try looking here : ​https://github.com/macports/macports-ports/pull/28680 mariadb-{LTS,dev} : updates ; boost188 ; LTS 11.8, 12.3 ; dev

Took a look at build-bot log for macos26 :

grep -A 15 'Installing .. dependencies' mariadb11-macOS26.log

The lzo2 dependency was introduced in mariadb-10.6 & is present in all later LTS releases.
I'll add lzo2 to depends_lib-append in PR28680 and git push --force
