缺乏動態鏈接庫的解決方法

缺乏動態鏈接庫.so--cannot open shared object file: No such file or directory

問題報錯

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

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

 總結下來主要有3種方法：

1. 用ln將須要的so文件連接到/usr/lib或者/lib這兩個默認的目錄下邊

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，而後刷新

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

能夠在cd /etc/ld.so.conf.d/目錄下添加*.conf文件,配置你的動態庫所在的位置 

而後執行sudo ldconfig
