在64位Linux上进行Mex编译-/usr/bin/ld:找不到-lstdc ++ [英] Mex compiling on 64 bit linux - /usr/bin/ld: cannot find -lstdc++

问题描述

好吧，我正在尝试在64位linux上编译一个mex文件，确切地说，是用Matlab 2013a编译的ubuntu.

Okay I am trying to compile a mex file on 64 bit linux, ubuntu to be precise with Matlab 2013a.

首先，它给出一个错误，它找不到GLIBCXX_3.4.15.这不属于 /usr/local/MATLAB/R2013a/sys/os/glnxa64/libstdc++.so.6.我发现此线程​​/usr/lib /libstdc++.so.6:找不到版本"GLIBCXX_3.4.15" ，并成功在/usr/local/MATLAB/R2013a/sys/os/glnxa64

First it gave a error that it could not find GLIBCXX_3.4.15. Which was not part of the /usr/local/MATLAB/R2013a/sys/os/glnxa64/libstdc++.so.6. I found this thread /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.15' not found and succesfully created a symbolic link ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.17 libstdc++.so.6 in /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

Now I tried to compile again and now I get /usr/bin/ld: cannot find -lstdc++ collect2: error: ld returned 1 exit status

这是输出

>> mex -v tload3.c

ps还有另一个标题大致相同的线程，

ps there is a another thread with about the same title, Error building MEX-files (MATLAB 2012a) on Kubuntu '/usr/bin/ld: cannot find -lstdc++', unfortunatly the answer, installing sudo apt-get install libstdc++6-4.4-dev did not work for me.

推荐答案

我遇到了同样的问题，并且对我有用

I had the same problem and this worked for me

导航到以下路径cd /usr/local/MATLAB/R2013a/sys/os/glnxa64/(您的路径可能会有所不同)，然后删除libstdc库(或更安全的重命名它)

Navigate to the following path cd /usr/local/MATLAB/R2013a/sys/os/glnxa64/, (your path might varies) then remove the libstdc library (or safer rename it)

sudo mv libstdc++.so.6 libstdc++.so.6.old

我具有相同的配置，使用Matlab 2013a的Ubuntu Linux 64位

I have the same configuration, Ubuntu Linux 64 bit with Matlab 2013a
