c++ - 无效的 MEX 文件 libmkl_rt.so : cannot open

Question

我有一个 MEX 文件，可以在 CentOS 7.7 和 MATLAB R2018b 上完美编译和运行。我可以使用 MATLAB R2016b 在 Ubuntu 16.04 上编译它，但是当我尝试运行它时，我得到了

libmkl_rt.so: cannot open shared object file: No such file or directory.

我试过了

setenv('LD_LIBRARY_PATH',[getenv('LD_LIBRARY_PATH'),':/opt/intel/compilers_and_libraries_2019.1.144/linux/mkl/lib/intel64_lin'])

和

setenv('LD_RUN_PATH',[getenv('LD_RUN_PATH'),':/opt/intel/compilers_and_libraries_2019.1.144/linux/mkl/lib/intel64_lin'])

根据 this thread ，没有运气。还是一样的问题。

这是我用来编译的命令:

mex -v -I/usr/include -I/opt/intel/mkl/include station_cov.cpp -L/lib64 -larmadillo -L/opt/intel/mkl/lib/intel64 -lmkl_core -lmkl_sequential

这似乎是一个路径问题，但我无法弄清楚我哪里出错了。任何帮助将不胜感激。

Answer 1

您的 MATLAB 版本 requires GCC 4.9.x用于编译 MEX 文件。你可能have version 5.3 instead .

使用 5.3 版编译时，您的二进制文件需要链接到 5.3 版或更新版本附带的 C++ 库。

MATLAB 是用 4.9 编译的，需要该版本的 C++ 库或更新的版本。

MATLAB 带有自己的 GCC C++ 库版本 (v 4.9)，并在加载 MEX 文件之前链接到它。当您的 MEX 文件被链接进来时，已经加载了一个版本的 C++ 库，但它是错误的版本。

有两种方法可以解决这个问题:

• 官方方法:安装 GCC 4.9.x，并通过向 mex 命令添加适当的参数来确保在编译 MEX 文件时使用它。您还必须重新编译您的依赖项(Armadillo 和 MKL，从您的 ldd 输出来看，它们似乎依赖于许多其他库)。

• 错误的方法:从 MATLAB 目录中删除 C++ 库，并让它使用系统附带的库(较新，因此应该可以工作)。我们正在谈论文件 /usr/local/MATLAB/R2016b/sys/os/glnxa64/libstdc++.so.6 和 /usr/local/MATLAB/R2016b/sys/os/glnxa64/libgcc_s.so.1。这个解决方案比另一个更容易，我不能推荐其他任何东西。我过去用许多不同版本的 Linux 和 MATLAB 做过这个，但可能没有用 Ubuntu 16 和 MATLAB R2016a，所以通过移动文件或重命名它们来仔细尝试，这样如果 MATLAB 不会，你可以撤消更改'开机。然而，这确实需要管理员权限，因此它不是对每个人都可行的解决方案。
