在源码安装mysql5.7系列时，出现如下错误：
错误现象：
CMake Error at cmake/boost.cmake:76 (MESSAGE):
You can download it with -DDOWNLOAD_BOOST=1 -DWITH_BOOST=<directory>
This CMake script will look for boost in <directory>. If it is not there,
it will download and unpack it (in that directory) for you.
If you are inside a firewall, you may need to use an http proxy:
export http_proxy=http://example.com:80
Call Stack (most recent call first):
cmake/boost.cmake:228 (COULD_NOT_FIND_BOOST)
CMakeLists.txt:452 (INCLUDE)
-- Configuring incomplete, errors occurred!
原因分析：没有boost包
解决方法：
1、在预编译时添加相应的选项：cmake . -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/usr/local/boost
[root@kongxl mysql-5.7.6-m16]# cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/data/mysql -DWITH_INNOBASE_STORAGE_ENGINE=1 -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/usr/local/boost
2、或者下载一个boost包，放到/usr/local/boost目录下，然后在cmake后面加选项-DWITH_BOOST=/usr/local/boost
[root@kongxl mysql-5.7.6-m16]# cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/data/mysql -DWITH_INNOBASE_STORAGE_ENGINE=1 -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_BOOST=/usr/local/boost
