Error while loading shared libraries: libimsl.so: cannot open shared object file

此问题纠结近30个小时后终于得到解决，期间用过很多方法，一一列举如下：

 

1：搜索资源得到这个http://ait.web.psi.ch/services/linux/hpc/hpc_user_cookbook/libraries/imsl/

 

Problem:

./lin_sol_svd_ex2
./lin_sol_svd_ex2: error while loading shared libraries: libimsl.so: cannot open shared object file: 
                     No such file or directory
ldd lin_sol_svd_ex2

     libdl.so.2 => /lib/libdl.so.2 (0x00804000)
     /lib/ld-linux.so.2 (0x00699000)

Solution: set LD_LIBRARY_PATH:

export LD_LIBRARY_PATH=$IMSL_LIB_DIR:$LD_LIBRARY_PATH
echo $LD_LIBRARY_PATH
/opt/imsl/imsl-6.0-intel/imsl/fnl600/lnxin100i32/lib:/opt/intel/intel-10.0/fc-10.0/lib:/opt/intel/intel-10.0/cc-10.0/lib

按照此方法没有有效的解决，不知道原因！

2：修改过 /etc/profile 以及home目录下的.bash_profile， 添加了imsl库的路径，问题依然没有解决！

 3：随后问百度，告诉我几个答案

 A：如此文所述http://blog.csdn.net/qiek/archive/2005/11/27/537636.aspx

按照这个方法问题得到有效解决：

步骤如下，

因为我系统中有其所需库文件，因此，我只用root用户 （似乎必须用root用户，因为在执行ldconfig时只能是root） 修改了/etc/ld.so.conf，添加了我的库路径/opt/imsl/imsl/install/imsl/fnl600/rdhin111e64/lib/， 添加过程中出现一个小小的错误，lib后面的“/”忘记写了，导致失效。 

 添加好以上路径后如下： 

include ld.so.conf.d/*.conf /opt/imsl/imsl/install/imsl/fnl600/rdhin111e64/lib/

 

然后用root用户执行 ldconfig，再 $ldd a.out

发现可以检索到相关库！

问题解决！
