直到版本 2013a，我都可以毫无问题地编译、链接和运行我的 C 网关和 Fortran 源混合 mex 函数(Windows、Linux 和 Mac)。在 R2014a-maci64 上编译和链接一切正常，但是当我尝试运行生成的 mex 函数时，我收到了以下消息:
Invalid MEX-file '/Users/name/MATLAB/mexaci64_R2014a/xxxx.mexmaci64':
dlopen(/Users/name/MATLAB/mexaci64_R2014a/xxxx.mexmaci64, 6): Symbol not found:
__gfortran_transfer_character_write
Referenced from: /Users/name/MATLAB/mexaci64_R2014a/xxxx.mexmaci64
Expected in: /Applications/MATLAB_R2014a.app/sys/os/maci64/libgfortran.3.dylib
in /Users/name/MATLAB/mexaci64_R2014a/xxxx.mexmaci64
我发现的第一件事是matlab自带的libgfortran.3.dylib似乎没有__gfortran_transfer_character_write(有人也可以检查一下吗？)，因为命令
nm libgfortran.3.dylib | grep __gfortran_transfer_character_write
什么也没显示。
我已用新库(例如 gfortran 4.9.1 或 4.8.2)替换了整个 Maci64 目录以获取
nm libgfortran.3.dylib | grep __gfortran_transfer_character_write
00000000000c7210 T __gfortran_transfer_character_write
这意味着那里有东西(“T”符号在文本(代码)部分)。但是，如果我再次重新编译混合 mex 函数(当然使用新的 gfortran 编译器和正确的路径)，错误消息仍然存在。
Fortran 写入命令(例如 write(6,*))似乎是问题所在，因为所有其他没有 Fortran 写入工作的混合 mex 函数。
有人可以指出我做错了什么吗？
非常感谢

最佳答案
实际上，MATLAB(或MEX)不支持高于4.3.x版本的gfortran，根据此页面:Supported and Compatible Compilers – Release 2014a .
我以前也遇到过同样的问题。我切换到gfortran-mp-4.3后，问题解决了。
关于c - 2014a 上的 Matlab C 网关和 Fortran 源混合 mex 函数，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/24976605/
