Mex 在 64 位 Linux 上编译 - /usr/bin/ld: 找不到 -lstdc++

好吧，我正在尝试在 64 位 linux（确切地说是 ubuntu）上使用 Matlab 2013a 编译一个 mex 文件。

首先它给出了一个找不到的错误GLIBCXX_3.4.15。这不属于/usr/local/MATLAB/R2013a/sys/os/glnxa64/libstdc++.so.6。我找到了这个线程/usr/lib/libstdc++.so.6：找不到版本“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 in /usr/local/MATLAB/R2013a/sys/os/glnxa64

现在我再次尝试编译，现在我得到了/usr/bin/ld: cannot find -lstdc++ collect2: error: ld returned 1 exit status

这是输出

>> mex -v tload3.c

ps 还有一个主题几乎相同的主题，在 Kubuntu '/usr/bin/ld: 找不到 -lstdc++' 上构建 MEX 文件 (MATLAB 2012a) 时出错，不幸的是答案是安装sudo apt-get install libstdc++6-4.4-dev不适合我。

使用 MATLAB 2013a 在 Ubuntu 13.04 上出现同样的问题。 我解决了它：

sudo mv /usr/local/MATLAB/R2013a/sys/os/glnxa64/libstdc++.so.6 /usr/local/MATLAB/R2013a/sys/os/glnxa64/libstdc++.so.6.old

保留备份以防万一。

然后是符号链接：

sudo ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.17 /usr/local/MATLAB/R2013a/sys/os/glnxa64/libstdc++.so.6
