2024/06/21(金)OpenLDAP 2.6.8 では、Cyrus-SASL 抜きの構築は出来ない

これも嵌ったので自分メモ:
OpenLDAP をソースコードから構築する場合、configure で指定するオプションに --without-cyrus-sasl を指定して、Cyrus-SASL のサポートを外すことが出来ます。
ところが、こうすると、 OpenLDAP 2.6.8 では、途中で下記のエラーを吐いて構築不能になるのです:
ld: error: version script assignment of 'OPENLDAP_2.200' to symbol 'ldap_host_connected_to' failed: symbol not defined

cc: error: linker command failed with exit code 1 (use -v to see invocation)
これは、Cyrus-SASL をインストールし、更に --without-cyrus-sasl のオプションを外さないとエラーが取れない。
弊社の使用形態では Cyrus-SASL は使わないため、このオプションは必須の形で指定していたが、嫌でも Cyrus-SASL をインストールし、サポートさせないといけない状態に…

このバージョンだけの問題なのか、本来は Cyrus-SASL と OpenLDAP はセットで使う仕様であるので、今後の強制的な方針なのかは判りません。
メンテナンス・運用管理の観点からは、出来る限り余計なものは入れたくないんだけどね・・・

2024/06/20(木)FreeBSD 13.3R で dovecot 2.3.21 はそのまま構築できない

FreeBSD 13.3 では、clang が Ver 17 になった影響か、dovecot 2.3.21 ではこんな感じで、コンパイルエラーになる:

当該ドメインがレジストリ的に有効期限切れで使用不能になった、みたいな通知だが、
2ヶ月くらい前に自動更新したばかりで、whois で確認してもドメインステータスには問題は無さそう。

恐らく、ドメイン更新料金を騙し取ろうとしているのだろう。
ドメインレジストラ業者でないと、入手できない個人情報を使っているので、たちが悪い。
今後、こういうのには注意が必要である。皆さまもご注意ください。
