1. yum安装
TODO
CentOS8使用yum安装的qemu版本为4.2.0，如果需要最新版本，需要从https://www.qemu.org/download/下载最新源码，编译安装。

CentOS8使用yum安装的qemu版本为4.2.0，如果需要最新版本，需要从https://www.qemu.org/download/下载最新源码，编译安装。
2.2. 编译wget https://download.qemu.org/qemu-6.1.0.tar.xz tar xvJf qemu-6.1.0.tar.xz cd qemu-6.1.0 ./configure make
如果使用GitLab上的master分支，可以：
git clone https://gitlab.com/qemu-project/qemu.git cd qemu git submodule init git submodule update --recursive ./configure make
当执行./configure会产生如下错误：
[rongtao@bogon qemu-6.1.0]$ ./configure Using './build' as the directory for build output ERROR: Cannot find Ninja
为了确保体系结构、KVM支持、调试功能，可以在配置阶段指令选项：
./configure '--target-list=x86_64-softmmu' '--enable-kvm' '--enable-debug'
安装Ninja见附录。安装Ninja之后，再次./configure，提示仍旧有错误：
$ ./configure Using './build' as the directory for build output The Meson build system Version: 0.55.3 Source dir: /home/rongtao/qemu-6.1.0 Build dir: /home/rongtao/qemu-6.1.0/build Build type: native build Project name: qemu Project version: 6.1.0 C compiler for the host machine: cc (gcc 8.4.1 "cc (GCC) 8.4.1 20200928 (Red Hat 8.4.1-1)") C linker for the host machine: cc ld.bfd 2.30-93 Host machine cpu family: x86_64 Host machine cpu: x86_64 ../meson.build:10: WARNING: Module unstable-keyval has no backwards or forwards compatibility and might not exist in future releases.

我们一个一个看。为了清晰，给出截图：
安装pixman即可，参见附录。接着再次./configure，即可成功。然后进行编译：

查看Qemu版本：
$ qemu-img --version qemu-img version 6.1.0 Copyright (c) 2003-2021 Fabrice Bellard and the QEMU Project developers
安装成功。
3. 参考链接- documentation/9psetup；

参考链接：How to Install Invoice Ninja on CentOS 7
Ninja下载：RPM包
这里使用RPM包安装，但是安装过程会提示需要Python2.7，正如centos.pkgs.org所说，ninja的依赖为：
emacs-filesystem - libc.so.6(GLIBC_2.15)(64bit) - libgcc_s.so.1()(64bit) - libgcc_s.so.1(GCC_3.0)(64bit) - libm.so.6()(64bit) - libstdc++.so.6()(64bit) - libstdc++.so.6(CXXABI_1.3)(64bit) - libstdc++.so.6(GLIBCXX_3.4)(64bit) - python(abi) = 2.7 rtld(GNU_HASH) - vim-filesystem -
直接使用yum安装python2.7就可以了：
$ sudo yum install python2 Last metadata expiration check: 0:47:34 ago on Thu 23 Sep 2021 08:41:15 AM CST.

然后再次安装ninja：
$ sudo rpm -i ninja-build-1.10.2-3.el7.x86_64.rpm
成功。
4.2. 安装pixman很简单
$ sudo yum install -y pixman pixman-devel
