MATLAB Coder: gmake: *** [Bayer_2Step_data.o] Error 1

When I use the MATLAB Coder in MATLAB 2018a I meet some trouble. Please notice that there are some '/' which should be '\' in those paths. How to correct those '/'? For example: C:\MinGW\include/stdio.h

Answer 1

[Walter Roberson]

"Please notice that there are some '/' which should be '\' in those paths. How to correct those '/'?"

No, those do not need to be changed. MS Windows uses / internally as the directory separator, but changes that to \ for display purposes. (The use of \ for display has to do with the fact that they did not want to have conflicts with the user of / for command line switches when they were designing directories back in the early MS DOS days, but the code itself was designed to use / )

The only time you must use \ instead of / is if you are using some of the old old DOS commands that assumed that command line switches could appear anywhere including immediately after a filename.

[Dawn Pan]

Then what's wrong with this error message? I originally suspected '/' is the reason why it can't locate the .h file.

[Walter Roberson]

I do not see any error about .h not being found.

In order to get the error message

In file included from C:/TDM-GCC-64/x86_64-w64-mingw32/include/stddef.h:7:0,
                 from C:/TDM-GCC-64/lib/gcc/x86_64-w64-mingw32/5.1.0/include/stddef.h:1,
                 from C:\MinGW\include/stdio.h:69,
                 from Bayer_2Step.h:13,
                 from Bayer_2Step_data.c:10:
C:/TDM-GCC-64/x86_64-w64-mingw32/include/crtdefs.h:35:19: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'typedef'
 __MINGW_EXTENSION typedef unsigned __int64 size_t;
                   ^

then the files

 C:/TDM-GCC-64/x86_64-w64-mingw32/include/crtdefs.h
 C:/TDM-GCC-64/x86_64-w64-mingw32/include/stddef.h

 C:\MinGW\include/stdio.h
 Bayer_2Step.h
 Bayer_2Step_data.c

all had to be found.

The message is complaining about a problem processing the line

__MINGW_EXTENSION typedef unsigned __int64 size_t;

saying that it expected something between the _MINGW_EXTENSION and the typedef -- in particular it expected an equal sign, a comma, a semi-colon, the word asm or the word __attribute_ .

Because of the error, size_t ends up not getting defined, and that triggers a number of other messages.

There are a few different ways this could happen. One of them is if somehow __MINGW_EXTENSION is not recognized as being defined and is being treated as the name of a variable. Another way is if you (or one of the files you included) missed an #endif -- one poster with a related problem accidentally used endif instead of #endif for example.

Thanks for your enthusiasm. I copied my project into a computer with MATLAB 2016a then the error was disappeared. Maybe there's something wrong with the compile environment in my computer.
