Boost【3】在 Linux 上安装

在《Boost【1】安装》中以 Windows 为例介绍 Boost 的安装，最近主要在 Linux 上开发，发现差异还是比较大的，于是又有了本文。

软件环境

  • Debian Buster/Bullseye

  • clang-11/gcc-10

apt install wget -y
apt install p7zip-full -y
# apt install clang-11 -y
# ln -s /usr/bin/clang-11 /usr/bin/clang
# ln -s /usr/bin/clang++-11 /usr/bin/clang++
# clang++ --version
apt install g++-10 -y
ln -s /usr/bin/gcc-10 /usr/bin/gcc
ln -s /usr/bin/g++-10 /usr/bin/g++
g++ -v
apt install python3-dev -y

apt 安装法

如果您怕麻烦，而且不在乎使用最新版本 Boost，还可以直接用 apt 安装 1.74 的版本：

1

# install b2
apt install libboost1.74-tools-dev
# install boost
apt install libboost1.74-all-dev

然后跳到文末的“测试安装”。

源码安装法

1. 下载

3
cd ~
# wget https://boostorg.jfrog.io/artifactory/main/release/1.76.0/source/boost_1_76_0.7z
wget https://boostorg.jfrog.io/artifactory/main/release/1.78.0/source/boost_1_78_0.7z

2. 解压

1
2
# 7z x boost_1_76_0.7z
7z x boost_1_78_0.7z

3. 编译和安装 b2

# use /usr to avoid setting PATH
INSTALL_DIR=/usr

# cd boost_1_76_0
cd boost_1_78_0
# if you have multiple compilers
# ./bootstrap.sh --cxx=clang++
./bootstrap.sh --with-python-version=3.7
cd tools/build
cp ../../b2 ./
apt install bison -y
./b2 install --prefix=$INSTALL_DIR
cd ../../
cp ./project-config.jam $HOME/user-config.jam

4. 用 b2 编译 Boost

1
2
# b2 install --build-type=complete --layout=versioned --prefix=$INSTALL_DIR --exec-prefix=$INSTALL_DIR
b2 install --prefix=$INSTALL_DIR --exec-prefix=$INSTALL_DIR
