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

locate libmysqlclient_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 / -name libmysqlclient_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
include ld.so.conf.d/*.conf
/usr/local/ssl/lib
/usr/lib64/mysql/
/usr/lin64/

ldconfig

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

source ~/.bashrc

4、重新编译

make clean
make
