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
