Liunx 运行用 Intel MKL 库文件的程序出错 “error while loading shared libraries libmkl_intel.so” 解决办法

编译例子：

gcc -o foo foo.c -I/opt/intel/mkl/10.1.0.015/include 
-L/opt/intel/mkl/10.1.0.015/lib/32 -lmkl_intel ... 

错误提示：

./foo: error while loading shared libraries
libmkl_intel.so: cannot open shared object file
No such file or directory

解决办法：在Liunx 环境变量中加入Intel MKL 库文件路径

 Intel 官网详解：

Before using the Intel® MKL shared libraries, update the system variable LD_LIBRARY_PATH to include the libraries location. For example, if the Intel MKL libraries are in the /opt/intel/mkl/10.1.0.015/lib/32 directory then the following command line can be used (assuming a bash shell):

export LD_LIBRARY_PATH=/opt/intel/mkl/lib/ia32:$LD_LIBRARY_PATH
