Haskell阴谋安装:缺少C库iw

Question

我正在运行Fedora 19 x64，并试图通过阴谋安装安装xmobar。在安装了一堆依赖项之后，我只能在

cabal: Missing dependency on a foreign library:
* Missing C library: iw

我找不到关于这个iw图书馆的任何东西，我有点不知道该如何继续下去。

据我所知，我已经安装了所有的标准c库。

sudo yum install glibc-common glibc glibc-devel glibc-headers glibc-utils glibc-devel      glib2-devel gcc-c++ gcc

Nothing to do

Answer 1

您的操作系统对库进行不同的打包。对于fedora，如果缺少库A，通常会找到名为libA和libA-devel的包。幸运的是，您不需要猜测-相反，只需问yum什么包有一些感兴趣的文件。下面，我询问了共享对象文件libiw.so。

yum whatprovides *libiw.so*
...
1:wireless-tools-devel-29-9.1.fc19.x86_64 : Development headers for the
                                      : wireless-tools package
Repo        : fedora
Matched from:
Filename    : /usr/lib64/libiw.so



1:wireless-tools-29-9.1.fc19.x86_64 : Wireless ethernet configuration tools
Repo        : installed
Matched from:
Provides    : libiw.so.29()(64bit)
Filename    : /lib64/libiw.so.29

我很惊讶Fedora会在没有这些软件包的情况下安装，但是如果是这样的话，那么获得这些包只需要一个yum install命令即可。

Answer 2

如果有人想在拱门上安装xmobar，

包含iw的缺少的包称为wireless_tools.

你可以用

pacman -S wireless_tools
