在运行程序时找不到libdlntsh.so急急急急！

xiaolittle

在linux下编译.cpp文件通过
[root@localhost chen]# g++ -o ex_oci9 ex_oci9.cpp -I/opt/ora9/product/9.2/rdbms/demo -I/opt/ora9/product/9.2/rdbms/public -L/opt/ora9/product/9.2/lib/ -lclntsh
但运行的时候报错
[root@localhost chen]# ./ex_oci9
./ex_oci9: error while loading shared libraries: libclntsh.so: cannot open shared object file: No such file or directory

我在$ORACLE_HOEM/lib下找到了libclntsh.so和libclntsh.so.9.0
不知道问题出在哪里，希望大家能够帮住我解决！谢谢！急急急急！

现在不知道怎么编译又出问题了
[oracle@localhost chen]$ g++ -o ex_oci2 ex_oci9.cpp -I/opt/ora9/product/9.2/rdbms/demo -I/opt/ora9/product/9.2/rdbms/public -L /opt/ora9/product/9.2/lib/-lclntsh
/usr/bin/ld: cannot open output file ex_oci2: Permission denied
collect2: ld returned 1 exit status
到底问题出在哪里亚

谢谢，我检查过/etc/ld.so.conf这个目录下有那个路径，但就是一运行就说找不到libclntsh.so郁闷，还有其他的可能的错误吗？大家踊跃发言亚！

xiaolittle

我重新安装了10的客户端，编译通过后，执行时还是出现问题：
[root@chen otl]# ./ex_oci1
./ex_oci1: error while loading shared libraries: libclntsh.so.10.1: cannot open shared object file: No such file or directory
不知道到底是怎么回事，希望高手能指点一二

xiaolittle

我的oracle环境变量
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
libclntsh.so.10.1就在这个目录下，不知道运行的时候系统根据什么来找动态连接库，为什么会找不到！

undeadboy

你用root运行程序，看看root的环境变量里有没有设oracle动态连接库路径

mq110

vi /etc/ld.so.conf 里面添加那个库的路径.然后执行ldconfig

tchhyc

echo $LD_LIBRARY_PATH 看下路径里有没有
