在编译mex下的vtk示例时找不到GLIBCXX [英] GLIBCXX not found when compiling vtk example under mex

问题描述

我一直试图按照这个例子在MATLAB中使用mex编译vtk，在Ubuntu 11.10上。我使用的mex命令如下：

I have been trying to follow this example for compiling vtk in MATLAB using mex, on an Ubuntu 11.10. The mex command I used is as follows:

mex -I/usr/include/vtk-5.6 vtk_file.cpp -L/usr/lib/ -lvtkFiltering -lvtkRendering -lvtkCommon

编译后我有一个 .mexa64 文件。

After compilation I have a .mexa64 file.

但是，当我尝试运行该文件时，最终会出现以下错误：

However, when I try to run the file I end up with the following error:

Invalid MEX-file '/home/bill/Documents/MATLAB/vtk/vtk_file.mexa64': 
/usr/local/MATLAB/R2011b/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6:
version `GLIBCXX_3.4.11' not found (required by /usr/lib/libvtkFiltering.so.5.6)

如何确保找到glibcxx？我会假设它将被默认包含在编译中。

How can I ensure that glibcxx is found? I would have assumed that it would be included by default in the compilation.

推荐答案

Matlab使用自己的glibc库，

Matlab uses its own glibc librarires, and it's often a big mess because of that.

为了解决这个问题，你应该首先尝试确保matlab使用支持的gcc版本。你在编译时会得到一个警告吗？

To solve that problem you should first try to ensure that matlab use a supported version of gcc. Do you get a warning about that when you compile?

如果你是sudoer，你也可以强制matlab使用标准的glibc，我做了，它工作正常）：

If you are sudoer, you can also "force" matlab to use the standard glibc, by doing something like that (I did it, and it works fine):

cd /usr/local/MATLAB/R2011a/sys/os/glnxa64
sudo mkdir old
sudo mv libstdc++.so.6* old
sudo ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6 libstdc++.so.6 

很多人在互联网上抱怨，有不同的解决方案，如果那两个不工作。

Many people complain about that on the internet, there are different solutions, if those two ones don't work.
