What compiler and processor architecture does AMTLAB use?

Hi all,

I am trying to use C codes in MATLAB windows. My codes are using a dll generated by labview and I can run them through Visual Studio but when calling the C function in MATLAB (through codegen), I get the errors "We don't know the Compiler" and "We don't know the ProcessorType architecture". This is an error from the "platdefines.h" header file generated by labview. I guess MATLAB doesn't use any of these compilers and I need to modify "platdefines.h" so it includes MATLAB compiler as well but I don't know how.

Any comment or advice is truly appreciated!

Please find the related part of "platdefines.h" file here:

#ifdef _WIN64

#define OpSystem kMSWin64

#else

#define OpSystem kMSWin32

#endif

#ifndef WindowSystem

#define WindowSystem kMSWin32WM

#endif

#if defined(__MWERKS__)

#define Compiler kMetroWerks

#elif defined(_MSC_VER) || defined(_NI_VC_)

#define Compiler kVisualC

#elif defined(__SC__) || defined(_NI_SC_)

#define Compiler kSymanCWin

#elif defined(__BORLANDC__) || defined(__BCPLUSPLUS__) || defined(_NI_BC_)

#define Compiler kBorlandC

#else

#error "We don't know the Compiler"

#endif

#ifdef _M_PPC

#define ProcessorType kPPC

#elif defined(_M_IX86)

#define ProcessorType kX86

#elif defined(_M_X64)

#define ProcessorType kX64

#elif defined(_M_ALPHA)

#define ProcessorType kDECAlpha

#elif Compiler == kBorlandC

#define ProcessorType kX86

#elif defined(_ARM_)

#define ProcessorType kARM

#else

#error "We don't know the ProcessorType architecture"

#endif

What did you configure with mex -setup and codegen -config

Hi walter, this is my mex and codegen config:

mex -setup C

cfg = coder.config('lib');

cfg.TargetLang = 'C';

[Walter Roberson]

Please show the output of

mex -v -setup C

[Fahimeh Dehghandehnavi]

Sorry for my late reply. This is the output of mex -v -setup C (I have Visual Studio 2022 isntalled on my computer and my MATLAB is 2021b).

Hi there, just wanna check if your problem has been solved. I recently also encountered the same problem. :-( I use MATLAB 2017b and LabVIEW 2018.

[Walter Roberson]

The problem turned out to be that the installed compiler was too new to be supported by that MATLAB release.

Answer 1

[Steven Lord]

The list of supported and compatible compilers for the current release is on this page.

[Fahimeh Dehghandehnavi]

Thank you!

I have Visual Studio 2022 installed. I guess I should use 2019 or earlier then.

[Walter Roberson]

Yes.
