尝试在 Fedora 上为 acpi_call 构建 (a)kmod 包，无法安装

我想为 Fedora 打包一个简单的内核模块 acpi_call。为此我遵循了RPM Fusion 上的 kmods2 说明并得到以下 SPEC 文件：

# Copyright © 2016 Martin Ueding <[email protected]>

# A lot of boilerplate taken from

%define kmod_name acpi_call

%global debug_package %{nil}

%description

A kernel simple module that enables you to call ACPI methods by writing the
method name followed by arguments to /proc/acpi/call.

This module is to be considered a proof-of-concept and has been superseeded by
projects like bbswitch. It allows you to tamper with your system and should be
used with caution.

* Sat Jul 23 2016 Martin Ueding <[email protected]> 1.1.0-1
- Initial packaging

看这个粘贴对于具有语法突出显示的版本。

它确实可以编译，rpmbuild -ba acpi_call.spec并且我确实得到了两个文件：

  • akmod-acpi_call-1.1.0-1.fc24.x86_64.rpm
  • kmod-acpi_call-1.1.0-1.fc24.x86_64.rpm

当我尝试使用 安装它们时dnf，我无法安装它们，因为-common缺少软件包：

# dnf install akmod-acpi_call-1.1.0-1.fc24.x86_64.rpm kmod-acpi_call-1.1.0-1.fc24.x86_64.rpm 
Last metadata expiration check: 0:47:46 ago on Sat Jul 23 11:03:54 2016.
Error: nothing provides acpi_call-kmod-common >= 1.1.0 needed by akmod-acpi_call-1.1.0-1.fc24.x86_64.
nothing provides acpi_call-kmod-common >= 1.1.0 needed by akmod-acpi_call-1.1.0-1.fc24.x86_64
(try to add '--allowerasing' to command line to replace conflicting packages)

我现在被困在这里了。没有-common创建任何软件包，并且安装这些软件包dnf似乎也不起作用。

我怎样才能把它放入一个包中？

kmodtool 需要一个*-kmod-common规范。这可以是非常简单的包，只包含基础知识。

%define modname yourmod

Name:           %{modname}-kmod-common

Version:        1.0
Release:        1%{?dist}.1
Summary:        Common files for your mod
Group:          System Environment/Kernel
License:        GPL
Source0:        ${name}-%{version}.tar.gz
BuildRoot:      %{_tmppath}/%{name}-%{version}-%{release}-root-%(%{__id_u} -n)
BuildArch:      noarch

构建它rpmbuild然后你可以打包所有东西createrepo
