标题: 请教：64位Intel fortran 调用64位Matlab出问题
本帖最后由 harptraveler 于 2018-10-22 02:18 编辑

各位大神，本人被从fortran调用matlab问题困扰了两个礼拜，特来求助，请大家不吝赐教！感激不尽！

我的操作环境

系统：64位win10；Matlab版本：2018a；Fortran编译器：Intel parallel studio XE 2017fortran + Microsoft visual studio 2017；编译平台：Debug x64

问题描述：

试图用VS调用Matlab，无论VS中的程序是什么（即便是一个空程序），总会对第一行报错，output如下：

1>------ Build started: Project: Console2, Configuration: Debug x64 ------
1>Compiling with Intel(R) Visual Fortran Compiler 17.0.7.272 [Intel(R) 64]...
1>Source1.f90
1>C:\Users\Rui\FORTRAN\Console2\Console2/Source1.f90(1): error #5078: Unrecognized token '?' skipped
1>C:\Users\Rui\FORTRAN\Console2\Console2/Source1.f90(1): error #5078: Unrecognized token '?' skipped
1>C:\Users\Rui\FORTRAN\Console2\Console2/Source1.f90(1): error #5078: Unrecognized token '?' skipped
1>compilation aborted for C:\Users\Rui\FORTRAN\Console2\Console2\Source1.f90 (code 1)
1>
1>Build log written to "file://C:\Users\Rui\FORTRAN\Console2\Console2\x64\Debug\BuildLog.htm"
1>Console2 - 4 error(s), 0 warning(s)
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

问题似乎出在Process source file上。当这一项为默认选项No的时候，没有上述问题，当然程序也无法编译。当把这一项改为Yes(/fpp)后，便会出现上述错误。

其他信息：

1.Matlab中用mex命令可以识别Intel Fortran

2.已在win10的环境变量中添加matlab路径

3.已将操作平台改为x64

4.已在项目-属性-Fortran-General里的AdditionalInclude Directories添加include

5. 已在项目-属性-Linker-General里的Additionallibrary directories里添加lib/win64/Microsoft

6. 已在项目-属性-linker-Input里的AdditionalDependencies里添加libmx.lib libmat.lib libeng.lib

谢谢大家！

检查 Source1.f90 文件的编码，是否是 ANSI ，或者是 UTF-8 之类的。
改成 ANSI 之后再试试

非常感谢您！把编码改成UTF-8之后（找不到ANSI），就没有这个问题了。但用matlab官网提供的例子测试时，依然有错，请您指教。

用了这个例子，测试成功！谢谢！https://ww2.mathworks.cn/help/matlab/matlab_external/call-matlab-functions-from-fortran-applications.html
