请教：linux中matlab中安装mex后，不能用
在linux中matlab调用一个fortran程序，安装mex后，还是不能用，请大家帮忙。下面是运行的情况：>> mex -setup
Using the 'mex -setup' command selects an options file that is
placed in ~/.matlab/R14 and used by default for 'mex'. An options
file in the current working directory or specified on the command line
overrides the default options file in ~/.matlab/R14.
Options files control which compiler to use, the compiler and link command
options, and the runtime libraries to link against.
To override the default options file, use the 'mex -f' command
(see 'mex -help' for more information).
The options files available for mex are:
1: /opt/matlab/bin/f90opts.sh :
Template Options file for building Fortran 90 MEX-files via the system ANSI compiler
2: /opt/matlab/bin/gccopts.sh :
Template Options file for building gcc MEX-files
3: /opt/matlab/bin/mexopts.sh :
Template Options file for building MEX-files via the system ANSI compiler
Enter the number of the options file to use as your default options file:
2
Overwrite /home/hzh/.matlab/R14/mexopts.sh (/n)?
y
/opt/matlab/bin/gccopts.sh is being copied to
/home/hzh/.matlab/R14/mexopts.sh
>> mex -g aa.f
/usr/bin/ld: cannot find -lstdc++
collect2: ld returned 1 exit status
mex: link of 'aa.mexglx' failed.
??? Error using ==> mex

这个选1试试看

选1试了，还是不行，请问一下，是不是要把调用的fortran程序先写为mex形式的fortran中的程序，然后在在matlab中mex+文件名，这样对吗？还有应该把文件存放在哪个路径？回复 板凳 zhaonatju 的帖子
个人对这方面也不在行！文件应放在Current Directory下吧
