无法链接到模块'rlm_python'：rlm_python.so

Question

我试图为freeradius 3.0.8创建一个python身份验证。我跟踪了this example。但是当我试图在调试模式下使用radiusd -X命令启动freeradius时，它显示了以下错误。

/usr/local/etc/raddb/mods-enabled/python[9]: Failed to link to module 'rlm_python': rlm_python.so: cannot open shared object file: No such file or directory

我查看了/usr/local/lib/文件夹，发现rlm_python模块不在那里。如何添加该模块？我在/raddb/mods-available/中的python模块如下所示。

  python {
  module = example

  mod_authorize = ${.module}
  func_authorize = authorize
}

感谢任何人的帮助。

根据发行版的不同，rlm_python并不总是打包。

基本的构建说明可以在这里找到：http://wiki.freeradius.org/building/Home

您还需要在系统上安装python-dev/python-devel包。如果python仍然不起作用，您可能需要手动指定python二进制文件的路径，方法是将其传递给configure，例如./configure --with-rlm-python-bin=/usr/bin/python2.7。

如果您只是想验证配置脚本是否选择了python cd src/modules/rlm_python; ./configure

在我的系统(macOS 10.11.6)上，找到python时的输出是：

configure: creating ./config.status
config.status: creating all.mk

一旦配置脚本找到了python二进制文件，它通常都会“正常工作”，因为它可以从python本身获得编译和链接标志。
