我最近遇到了一个问题。它曾经是我记得很好的工作,但几周后我再次尝试MEX在MATLAB中的一个fortran 77文件,但它给了我一个奇怪的错误。
好的,我使用名为mexopts_f77.bat
的Gnumex创建了MEX选项文件。
这是我在MATLAB中运行的命令:
mex -v -f C:\Omid\Other\Gnumex\mexopts_f77.bat -c sodex.f decsol.f
这就是我得到的错误:
-> Options file specified on command line
----------------------------------------------------------------
-> Options file = C:\Omid\Other\Gnumex\mexopts_f77.bat

我认为问题出在-fcase-upper
选项上。我查了一下,但找不到任何重新定位gcc
选项的信息。
我在我的选项文件中手动将gcc
更改为g77
并成功创建了目标文件但在最后一步中仍然出现错误,我尝试将目标文件链接到主要文件名为vdpsodex.F
的脚本并创建MEX文件。根据要求,我包括选项文件:

现在上面的代码确实给了我目标文件,但是当我尝试使用下面的命令制作最终的MEX文件时:
mex -v -f C:\Omid\Other\Gnumex\mexopts_f77.bat vdpsodex.F sodex.obj decsol.obj
它给了我以下错误:

答案 0 :(得分:0)
强调文本最后,我能够指出问题,我认为对于可能面临同样问题(或类似于此问题)的其他人来说,分享答案可能会有所帮助。我只想提一下,我在第一时间看起来很奇怪,因为我使用由Gnumex创建的选项文件MEX使用完全相同的文件并且根本没有问题。我刚刚注意到,因为我之前改变了我的MinGW构建,即使我重新创建选项文件(mexopts_f77.bat
),我也无法再使用相同的Fortran文件。
无论如何,长话短说我发现这个link非常有用。基本上,它建议下载五个包并将它们提取到MinGw的根目录。其中四个链接仍然存在。其中一个已经死了,但我通过谷歌搜索包名来找到它。您在下面看到的是包的更新链接。
最后但并非最不重要的是,如果您的g77不使用Gnumex制作的选项文件,则可以使用以下解决方案:
C:\MinGW
mexopt_f77.bat
使用以下语法使用Fortran脚本。
mex -f [ options-file ] [fortran-file.f]
如果您需要将某些文件链接到主脚本,则必须先将它们编译为目标文件,然后将它们链接起来。
mex -f [ options-file ] -c [ linkfile1.f ] [ linkfile2.f ]
mex -f [ options-file ] [ fortran-file.f ] [ linkfile1.obj ] [ linkfile2。 OBJ
