无法使用Rakudo Perl 6 zef安装Readline

Question

我在尝试安装Readline。

(该系统是18.3，Lubuntu17.10也是如此)。

$ zef install Readline

安装过程开始，但稍后使用下列消息中止：

locate libreadline.so提供以下输出：

/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

许多发行版，包括debian/ubuntu和朋友，鼓励在打包之间进行一定的分离，在debian.org包装文档中提供更多信息。

特别是，它们鼓励为某些版本(如.so.1)分发共享库，这些版本是与“非版本”.so分离的其他包的依赖项，后者更典型地用于“开发”(在以-dev结尾的分发包中)。

来自上述文档：

请注意，开发包应该包含一个没有版本号的相关共享库的符号链接。例如：/usr/lib/x86_64-linux-gnu/libfoo.so -> libfoo.so.1

对于readline，该链接位于libreadline-dev包中，它可以安装在mint/ubuntu/debian类型的系统上，如：sudo apt-get install libreadline-dev

Perl 6 NativeCall文档也讨论了这一点：

如果您编写本机(‘foo’)，NativeCall将在类似Unix的系统( OS上的libfoo.dynlib，win32上的foo.dll )下搜索libfoo.so。在大多数现代系统中，它将要求您或模块的用户安装开发包，因为建议始终向共享库提供API/ABI版本，因此libfoo.so结束时通常是一个只由开发包提供的符号链接。 为了避免这种情况，本机特性允许您指定API/ABI版本。它可以是一个完整的版本，也可以只是其中的一部分。(尝试坚持主要版本，一些BSD代码不关心次要。)

它看起来像Readline 不指定特定的API/ABI版本。。(也许应该这样？)

因为它没有，所以它将查找不版本的共享库(普通.so)。

Answer 2

见这个perl6 6-重新读入的问题。

在@drforr有时间整理版本之前，我创建了一个临时分叉，它可以很好地安装在Ubuntu18.04和所有的发行版上，使用li威libreadline 7。

要安装模块：

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

如果您想自己修补这个问题(1行补丁)，可以按照我对一个相关问题的评论中的说明进行。
