mongo4.2.6 在x86_64 环境下编译

x86_64编译

编译要求，这部分内容来自安装包
* A modern C++ compiler capable of compiling C++17. One of the following is required:
    * GCC 8.0 or newer
    * Clang 7.0 (or Apple XCode 10.0 Clang) or newer
    * Visual Studio 2017 version 15.9 or newer (See Windows section below for details)
* On Linux and macOS, the libcurl library and header is required. MacOS includes libcurl.
    * Fedora/RHEL - `dnf install libcurl-devel`
    * Ubuntu/Debian - `apt-get install libcurl-dev`
* Python 3.7.x and Pip modules:
  * See the section "Python Prerequisites" below.
  

In order to build MongoDB, Python 3.7.x is required, and several Python modules. To i
nstall
 the required Python modules, run:

     $ pip3 install -r etc/pip/compile-requirements.txt

Note: If the `pip3` command is not available, `pip` without a suffix may be the pip c
ommand
associated with Python 3.7.x.
  
MongoDB supports the following architectures: arm64, ppc64le, s390x, and x86-64.

1. 编译gcc 8.4

wget https://mirrors.tuna.tsinghua.edu.cn/gnu/gcc/gcc-8.4.0/gcc-8.4.0.tar.gz
cd gcc-8.4.0
contrib/download_prerequisites

./configure --enable-checking=release --enable-language=c,c++ --disable-multilib
make -j 128
# 默认路径在/usr/local,lib库在/usr/local/lib64
make install
/usr/local/bin/gcc -v

# 查看是否安装成功
gcc -v

2. 编译安装python3.7

安装依赖

yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make libffi-devel

安装python

# 解压缩
tar -zxvf Python-3.7.0.tgz

# 进入解压后的目录，依次执行下面命令进行手动编译
./configure prefix=/usr/local/python3 
make && make install

设置环境变量

export PATH=/usr/local/python3/bin:$PATH

3. 编译mongodb4.2.6

安装依赖

yum install libcurl-devel -y

安装python依赖

pip3.7 install -r etc/pip/compile-requirements.txt
pip3 install scons

编译mongodb

# 编译所有组件，编译出来的文件超大, 编译花费超过半个小时
python3.7 buildscripts/scons.py all MONGO_VERSION=4.3.1 -j 8

# 编译核心组件 mongod, mongos, shell
scons core MONGO_VERSION=4.3.1 -j 8
python buildscripts/scons.py core MONGO_VERSION=3.4.0 -j 8 CC=/opt/rh/devtoolset-8/root/usr/bin/gcc CXX=/opt/rh/devtoolset-8/root/usr/bin/g++
# 安装（ 安装到/opt/mongo ）
scons --prefix=/opt/mongo  install

# 如果需要lib库和include头文件 需要加上 –full 参数如下，这个测试未通过
scons –prefix=/opt/mongo  –full install

编译后需要使用strip取消调试信息

执行 ./mongod 报错

[root@node1 mongo-r4.2.6]# ./mongod
./mongod: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by ./mongod)
./mongod: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.22' not found (required by ./mongod)
./mongod: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by ./mongod)
./mongod: /lib64/libstdc++.so.6: version `CXXABI_1.3.8' not found (required by ./mongod)

查找 libstdc++.so.6 所在目录并设置环境变量

 export LD_LIBRARY_PATH=/usr/local/lib64/
