使用mkl，加载共享库时出错：libmkl_intel_lp64.so [英] using mkl, error while loading shared libraries: libmkl_intel_lp64.so

问题描述

我在使用 mkl 库时几乎是新手。所以请原谅，如果它看起来很愚蠢。我尝试在 [here] 教程中使用 ifort -mkl dgemm_example.f ，然后运行可执行文件。这是错误：

  ./ a.out：加载共享库时出错：libmkl_intel_lp64.so：无法打开共享对象文件：没有这样的文件或目录
  

我也搜索了类似的问题，但让我更加困惑。
你有什么想法吗？
dgemm_example.f

解决方案

您必须设置LD_LIBRARY_PATH环境变量，否则共享库将在运行时找不到。

在运行程序之前，在（bash）shell中输入 export LD_LIBRARY_PATH = / path / to / your / library / directory 代码。

如果您使用的是Ubuntu，您可以使用 /etc/ld.so.conf.d中的配置文件自动设置此变量/ ，请参阅 Ubuntu帮助。类似的机制可用于其他分发。

I'm almost new in using mkl libraries. So excuse me if it seems silly. I tried to run an example in tutorial [here] with ifort -mkl dgemm_example.f ,then run the executable file. Here is the error:

./a.out: error while loading shared libraries: libmkl_intel_lp64.so: cannot open shared object file: No such file or directory

I also searched for the similar problems but it baffled me more. do you have any idea? dgemm_example.f

解决方案

You have to set the LD_LIBRARY_PATH environment variable, otherwise the shared library will not be found at run time.

Before running your program, type export LD_LIBRARY_PATH=/path/to/your/library/directory in the (bash) shell in which you want to run your code.

If you are using Ubuntu, you can set this variable automatically by using configuration files in /etc/ld.so.conf.d/, see Ubuntu help. Similar mechanisms are available for other distributions.
