安裝其實挺簡單，下載原始碼編譯即可
git clone https://gitlab.com/qemu-project/qemu.git
cd qemu
git submodule init
git submodule update --recursive
git checkout xxxxxx # 對應版本號
mkdir build
cd build
../configure --enable-debug
make -j2
make install # 安裝
安裝完后可以看到各種命令
[root@test build]# qemu-

但是安裝這個軟體，又需要各種其他的依賴
比方說Python3
# 依賴安裝，視情況而定
yum -y install zlib-devel libffi-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
yum install gcc -y
# 下載安裝包
wget https://www.python.org/ftp/python/3.7.4/Python-3.7.4.tgz
mv Python-3.7.4.tgz /usr/local/
mkdir /usr/local/python3
cd /usr/local/
tar -xvf Python-3.7.4.tgz
cd /usr/local/Python-3.7.4/
# 編譯安裝
./configure --prefix=/usr/local/python3
make & make install
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
比方說 Ninja
apt install re2c
git clone git://github.com/ninja-build/ninja.git && cd ninja
./configure.py --bootstrap
sudo cp ninja /usr/bin/
ninja --version # 查看安裝版本
比方說gcc7.5（要求版本大于某個特定版本號）
# 安裝相關依賴
sudo yum -y update
sudo yum -y install bzip2 wget gcc gcc-c++ gmp-devel mpfr-devel libmpc-devel make
sudo yum -y install zlib
sudo yum -y install zlib-devel
# 下載安裝包
wget https://ftp.gnu.org/gnu/gcc/gcc-7.5.0/gcc-7.5.0.tar.gz
tar -zxvf gcc-7.5.0.tar.gz
cd gcc-7.5.0
# 其他依賴
./contrib/download_prerequisites
mkdir gcc-build-7.5
cd gcc-build-7.5
# 編譯
../configure --enable-bootstrap --enable-shared --enable-threads=posix --enable-checking=release --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object --enable-linker-build-id --with-linker-hash-style=gnu --enable-languages=c,c++,go,lto --enable-plugin --enable-initfini-array --disable-libgcj --enable-gnu-indirect-function --with-tune=generic --disable-multilib
make -j4
make install
gcc -v
# 檢查動態庫 & 查找新生成的動態庫
strings /usr/lib64/libstdc++.so.6 | grep GLIBC
find / -xdev -name "libstdc++.so*"
# 鏈接新的動態庫
cp /usr/local/lib64/libstdc++.so.6.0.24 /usr/lib64/
rm -rf /usr/lib64/libstdc++.so.6
ln -s /usr/local/lib64/libstdc++.so.6.0.24 /usr/lib64/libstdc++.so.6
# 添加環境變數
# 在PATH里面追加 /usr/local/bin
# 添加 LD_LIBRARY_PATH、CC、CXX
# bash_profile 類似于
PATH=$PATH:$HOME/.local/bin:$HOME/bin:/usr/local/bin
LD_LIBRARY_PATH=/usr/local/lib64:$LD_LIBRARY_PATH
CC=/usr/local/bin/gcc
CXX=/usr/local/bin/g++
export PATH
export LD_LIBRARY_PATH
export CC
export CXX
# 生效環境變數
source ~/.bash_profile
比如glib2和glib2-devel
yum install -y glib2 glib2-devel
比如 libmount-devel pixman-devel
yum install -y libmount-devel pixman-devel
