编译安装时出现/usr/bin/ld: cannot find -lxxx故障的解决方法 编译安装时出现/usr/bin/ld: cannot find -lmysqlclient_r故障的解决方法

1、查看依赖文件位置locate libmysqlclient_r

locatelibmysqlclient_r
/usr/lib64/mysql/libmysqlclient_r.so
/usr/lib64/mysql/libmysqlclient_r.so.16
/usr/lib64/mysql/libmysqlclient_r.so.16.0.0

发现文件不存在

ll/usr/lib64/mysql/libmysqlclient_r.so
ll/usr/lib64/mysql/libmysqlclient_r.so.16
ll/usr/lib64/mysql/libmysqlclient_r.so.16.0.0

查找系统是否存在该文件

find/-namelibmysqlclient_r*
/usr/lib64/libmysqlclient_r.so.14.0.0
/usr/lib64/libmysqlclient_r.so.12
/usr/lib64/libmysqlclient_r.so.12.0.0
/usr/lib64/libmysqlclient_r.so.16.0.0
/usr/lib64/libmysqlclient_r.so.16
/usr/lib64/libmysqlclient_r.so.15.0.0
/usr/lib64/libmysqlclient_r.so.15
/usr/lib64/libmysqlclient_r.so.14

2、把找到的文件指向locate中定义的文件

ln-sf/usr/lib64/libmysqlclient_r.so.16/usr/lib64/mysql/libmysqlclient_r.so
ln-sf/usr/lib64/libmysqlclient_r.so.16/usr/lib64/mysql/libmysqlclient_r.so.16
ln-sf/usr/lib64/libmysqlclient_r.so.16/usr/lib64/mysql/libmysqlclient_r.so.16.0.0

3、修改配置和环境变量

vim/etc/ld.so.conf
includeld.so.conf.d/*.conf
/usr/local/ssl/lib
/usr/lib64/mysql/
/usr/lin64/

ldconfig

vim~/.bashrc
exportLD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib64/mysql/
exportLIBRARY_PATH=/usr/lib64/mysql/:$LIBRARY_PATH

source~/.bashrc

4、重新编译

makeclean
make
