缺乏动态链接库的解决方法

缺乏动态链接库.so--cannot open shared object file: No such file or directory

问题报错

error while loading shared libraries: libfl.so.2: cannot open shared object file: No such file or directory

====================================================

 总结下来主要有3种方法：

1. 用ln将须要的so文件连接到/usr/lib或者/lib这两个默认的目录下边

ln -s /where/you/install/lib/*.so /usr/lib

sudo ldconfig

 

2.修改LD_LIBRARY_PATH

export LD_LIBRARY_PATH=/where/you/install/lib:$LD_LIBRARY_PATH

sudo ldconfig

 

3.修改/etc/ld.so.conf，而后刷新

vim /etc/ld.so.conf

add /where/you/install/lib

sudo ldconfig

 

4.若是

cmj@cmjUb:~/codes$ cat /etc/ld.so.conf

include /etc/ld.so.conf.d/*.conf

能够在cd /etc/ld.so.conf.d/目录下添加*.conf文件,配置你的动态库所在的位置 

而后执行sudo ldconfig
