c - MATLAB(linux) 找不到 gcc

Question

我尝试在 MATALAB 中编译，但似乎 MATLAB 找不到 gcc:

Error using mex
No supported compiler or SDK was found. For options, visit 
http://www.mathworks.com/support/compilers/R2014a/glnxa64.

Error in compile (line 439)
mex(args{:});

>> mex -setup
MEX configured to use 'gcc' for C language compilation.
Warning: The MATLAB C and Fortran API has changed to support MATLAB
variables with more than 2^32-1 elements. In the near future
you will be required to update your code to utilize the
new API. You can find more information about this at:
http://www.mathworks.com/help/matlab/matlab_external/upgrading-mex-files-to-use-64-bit-api.html.

To choose a different language, select one from the following:
mex -setup C++ 
mex -setup FORTRAN

但是我已经使用apt-get install gcc安装了gcc，然后输入gcc -v可以得到如下信息:

gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1) 

我该如何解决这个问题？

Answer 1

将我的评论转换成这个答案:

错误信息告诉你去http://mathworks.com/support/compilers/R2014a/glnxa64 ，其中将 gcc 4.7.x 列为受支持的编译器，但您有 4.8.2。

所以你需要安装GCC 4.7。在 Ubuntu 上，这可以通过以下方式完成:

sudo apt-get install gcc-4.7
