1、判断是否已下载 mysqlclient 相关文件，至于是什么相关文件，应该能看得出来吧。

linux下用C语言写MySQL程序，用如下命令编译时出错： [xitong@localhost mysql]$ gcc -o mysql mysql.c -lmysqlclient 错误如下: /usr.../bin/ld: cannot find -lmysqlclient collect2: ld 返回 1 解决方法： 用locate命令查找mysqlclient所在目录，如下所示： [xitong@localhost...local/mysql/lib/mysql，如下： [xitong@localhost mysql]$ gcc -o mysql mysql.c -L/usr/local/mysql/lib/mysql -lmysqlclient

用“-Wl,-Bstatic”指定链接静态库，使用“-Wl,-Bdynamic”指定链接共享库，使用示例： -Wl,-Bstatic -lmysqlclient_r -lssl -lcrypto -
# 指定编译工具 CC=g++ # 依赖库 LIB=-lmysqlclient \ -I/usr/include/mysql/ \ -L/usr/lib/mysql # 64位系统编译
options libs="-L$pkglibdir" libs="$libs -l " 替换成： # Create options libs="-L$pkglibdir" libs="$libs -lmysqlclient
---- cannot find -lmysqlclient 这个问题的解决方案，之前用CentOS是有一份，但是我发现Ubuntu的解决方案和CentOS的不同，于是对原教程进行了修改： 问题解决：...cannot find -lmysqlclient 问题都不大的哈。
options libs="-L$pkglibdir" libs="$libs -l " 改为 # Create options libs="-L$pkglibdir" libs="$libs -lmysqlclient

EXTRA_LIBS 行，在行末添加 ‘ -llber ‘ 保存退出再次make即可 EXTRA_LIBS 行： EXTRA_LIBS = -lcrypt -lz -lexslt -lcrypt -lrt -lmysqlclient
