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

Question

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

"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.

MATLAB: Do I receive several compiling errors when trying to compile a C++ engine application using the Borland Free Compiler with the MATLAB Compiler

								

								
The compiling errors are coming from the stdlib.h file. This file is supposed to be a standard ANSI C header file, but in Borlands free compiler this is not the case. Explicitly defining the following symbol alleviates the problem:
 #define __STDC__ 1
The _STDC_ symbol is Borland specific and forces standard C.
Note: We have found several similar caveats with the Borland Free Compiler (v5.5). If possible, creating a C engine application will result in fewer compile and link issues.
						    
						
MATLAB: Linux RedHat 5 Enterprise – R2013a – LoadLibrary Error

								

								
The correction was to remove the __cdecl stack command all together. It turns out that linux gcc normally adds this in automatically for 64 bit systems making it redundant. (the best I could understand)
