CentOS/Redflag 7.3安装qemu 5.0记录

安装其实挺简单,下载源码编译即可

git clone https://gitlab.com/qemu-project/qemu.git cd qemu git submodule init git submodule update --recursive git checkout xxxxxx # 对应版本号 mkdir build cd build ../configure --enable-debug make -j2 make install  # 安装 

安装完后可以看到各种命令

[root@test build]# qemu- qemu-aarch64              qemu-img                  qemu-mipsn32el            qemu-riscv64              qemu-system-arm           qemu-system-mips64el      qemu-system-s390x         qemu-tilegx qemu-aarch64_be           qemu-io                   qemu-nbd                  qemu-s390x                qemu-system-cris          qemu-system-mipsel        qemu-system-sh4           qemu-x86_64 qemu-alpha                qemu-m68k                 qemu-nios2                qemu-sh4                  qemu-system-hppa          qemu-system-moxie         qemu-system-sh4eb         qemu-xtensa qemu-arm                  qemu-microblaze           qemu-or1k                 qemu-sh4eb                qemu-system-i386          qemu-system-nios2         qemu-system-sparc         qemu-xtensaeb qemu-armeb                qemu-microblazeel         qemu-ppc                  qemu-sparc                qemu-system-lm32          qemu-system-or1k          qemu-system-sparc64 qemu-cris                 qemu-mips                 qemu-ppc64                qemu-sparc32plus          qemu-system-m68k          qemu-system-ppc           qemu-system-tricore qemu-edid                 qemu-mips64               qemu-ppc64abi32           qemu-sparc64              qemu-system-microblaze    qemu-system-ppc64         qemu-system-unicore32 qemu-ga                   qemu-mips64el             qemu-ppc64le              qemu-storage-daemon       qemu-system-microblazeel  qemu-system-riscv32       qemu-system-x86_64 qemu-hppa                 qemu-mipsel               qemu-pr-helper            qemu-system-aarch64       qemu-system-mips          qemu-system-riscv64       qemu-system-xtensa qemu-i386                 qemu-mipsn32              qemu-riscv32              qemu-system-alpha         qemu-system-mips64        qemu-system-rx            qemu-system-xtensaeb 

但是安装这个软件,又需要各种其他的依赖

比方说Python3

# 依赖安装,视情况而定 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  # 下载安装包 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/  # 编译安装 ./configure --prefix=/usr/local/python3  make & make install  ln -s /usr/local/python3/bin/python3  /usr/bin/python3 

比方说 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  # 查看安装版本 

比方说gcc7.5(要求版本大于某个特定版本号)

# 安装相关依赖 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  # 下载安装包 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  # 其他依赖 ./contrib/download_prerequisites  mkdir  gcc-build-7.5  cd  gcc-build-7.5  # 编译 ../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  # 检查动态库 & 查找新生成的动态库 strings /usr/lib64/libstdc++.so.6 | grep GLIBC  find / -xdev -name "libstdc++.so*"  # 链接新的动态库 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  # 添加环境变量 # 在PATH里面追加 /usr/local/bin # 添加 LD_LIBRARY_PATH、CC、CXX # bash_profile 类似于 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  # 生效环境变量 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
