Matlab Coder, Compiler can't find "tmwtypes.h"

267 views (last 30 days)
Hello, I got Matlab Code from the Neural Net Pattern Recognition Toolbox and I tried to generate C++ Code with the Matlab Coder. But when I select Static Library or Source Code, Atmel AVR(8-bit) as Device (for Arduino) and the Arduino AVR toolchain the Arduino IDE always returns:
sketch\generated_code\interface\_coder_NeuralNetwork_api.c:12:22: fatal error: tmwtypes.h: No such file or directory
#include "tmwtypes.h"
Why didn't the Matlab Coder create that Library?

Problem solved.
Just use the Windows search, look for the filename on your HDD and copy it to your project folder!

There might be a few files with the same name "tmwtypes.h". To be safe, you should always use the one in: matlabroot\extern\include.

If anybody had problem in matlab:
c:\program files\matlab\r2019a\extern\include\matrix.h(683): fatal error C1083: Cannot open include file: “tmwtypes.h”: No such file or directory.
You can solve it in this way:
Find the matrix.h, row 683,change “ include<tmwtypes.h> into "include“tmwtypes.h”".

Aren't I am doing exactly the same when I tick the lib option in the matlab coder? The help says:" lib for embeddable C/C++ static libraries " When I type " codegen NeuralNetwork -args {1} -config:lib " in the command window I always get a error:
??? Index expression out of bounds. Attempted to access element 5. The valid range is 1-1. More information Error in ==> NeuralNetwork Line: 12 Column: 22 Code generation failed: View Error Report Error using codegen
In Line 12 I am indexing the input value of the Function (which should be a inf x 5 Matrix) in the fifth column.
Am I using the codegen command wrong? How can I get the missing tmwtypes.h file?
