Не удается установить Readline с помощью Rakudo Perl 6 zef

Question

Я пытаюсь установить Readline.

(Система Linux Mint Mate 18.3, то же самое относится и к Lubuntu 17.10).

$ zef install Readline

Процесс установки начинается, но позже прерывается со следующими сообщениями:

locate libreadline.so дает следующий вывод:

/lib/x86_64-linux-gnu/libreadline.so.5
/lib/x86_64-linux-gnu/libreadline.so.5.2
/lib/x86_64-linux-gnu/libreadline.so.6
/lib/x86_64-linux-gnu/libreadline.so.6.3

Answer 1

Многие дистрибутивы, включая debian/ubuntu и друзей, поощряют определенное разделение между пакетами, более подробную информацию можно найти в документации по пакетам debian.org.

В частности, они поощряют распространение общих библиотек для определенных версий (таких как .so.1) которые являются зависимостями других пакетов отдельно от "неверсированных" .so которые чаще используются для "разработки" (в дистрибутивах, заканчивающихся на -dev).

Из приведенных выше документов:

Обратите внимание, что пакет разработки должен содержать символическую ссылку для связанной общей библиотеки без номера версии. Например: /usr/lib/x86_64-linux-gnu/libfoo.so -> libfoo.so.1

Для readline эта ссылка находится в libreadline-dev пакет, который можно установить в системах типа mint / ubuntu / debian: sudo apt-get install libreadline-dev

Документы Perl 6 NativeCall также обсуждают это:

Если вы пишете native('foo'), NativeCall будет искать libfoo.so в Unix-подобной системе (libfoo.dynlib в OS X, foo.dll в win32). В большинстве современных систем вам или пользователю вашего модуля потребуется установить пакет разработки, потому что рекомендуется всегда предоставлять версию API/ABI для общей библиотеки, поэтому libfoo.so часто заканчивается символической ссылкой, предоставляемой только разработкой. пакет.

Чтобы избежать этого, нативная черта позволяет вам указать версию API/ABI. Это может быть полная версия или только ее часть. (Попробуйте придерживаться версии Major, для некоторого кода BSD все равно для Minor.)

Похоже, что Readline не указывает конкретную версию API/ABI. (возможно, так и должно быть?)

Поскольку это не так, он будет искать неверсированную разделяемую библиотеку (обычный .so).

Answer 2

Смотрите эту проблему perl6-readline.

Пока @drforr не успел разобраться с версиями, я создал временный форк, который прекрасно работает на Ubuntu 18.04 и всех дистрибутивах с использованием libreadline версии 7.

Чтобы установить модуль:

$ zef install https://github.com/nxadm/perl6-readline.git
