随笔-杂散

当编译的时候，提示什么什么库没找到的时候
CentOS：

# yum search all 库的名称

例如：致命错误：mysql/mysql.h：没有那个文件或目录

root:# yum search all mysql | grep i686
qt-mysql.i686 : MySQL driver for Qt's SQL classes
qt3-MySQL.i686 : MySQL drivers for Qt 3's SQL classes
qt5-qtbase-mysql.i686 : MySQL driver for Qt5's SQL classes
mariadb-devel.i686 : Files for development of MariaDB/MySQL applications
mariadb-libs.i686 : The shared libraries required for MariaDB/MySQL clients
mariadb-embedded.i686 : MariaDB as an embeddable library
mariadb-embedded-devel.i686 : Development files for MariaDB as an embeddable
unixODBC.i686 : A complete ODBC driver manager for Linux

安装mariadb-devel.i686后解决编译问题(i686表示32位，x86_64表示64)
