#linux系统如何查看分配给matlab的内存

本文记录了在64位Linux环境下使用Matlab2013a编译mex文件时遇到的问题及解决过程。主要问题是由于GLIBCXX_3.4.15版本不匹配导致的编译错误，通过创建符号链接来解决问题。此外，还提到了gcc版本的兼容性问题。

好吧，我正在尝试在64位linux上编译一个mex文件，确切地说是在Matlab 2013a上编译为ubuntu。

首先，它给出了一个找不到GLIBCXX_3.4.15的错误。这不是/usr/local/MATLAB/R2013a/sys/os/glnxa64/libstdc++.so.6一部分。我发现此线程/usr/lib/libstdc++.so.6：未找到版本“ GLIBCXX_3.4.15”，并成功创建了符号链接ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.17 libstdc++.so.6 /usr/local/MATLAB/R2013a/sys/os/glnxa64 ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.17 libstdc++.so.6 /usr/local/MATLAB/R2013a/sys/os/glnxa64

现在我尝试再次编译，现在我得到/usr/bin/ld: cannot find -lstdc++ collect2: error: ld returned 1 exit status

这是输出

>> mex -v tload3.c

ps还有一个标题大致相同的线程，在Kubuntu'/ usr / bin / ld：构建MEX文件(MATLAB 2012a)时出错：找不到-lstdc ++' ，不幸的是，安装sudo apt-get install libstdc++6-4.4-dev对我不起作用。
