c - MATLAB(linux)找不到gcc,第1张

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

但我已经使用apt-get install gcc安装了gcc,并输入gcc -v可以获得以下信息:

将我的评论转换为此答案:

错误消息告诉您转到http://mathworks.com/support/compilers/R2014a/glnxa64,它将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,这可以使用:

完成
sudo apt-get install gcc-4.7
