Porting into TriCore Environment

[SUBBU3881]

Already MICROPY_PY_BUILTINS_PROPERTY is set to 1. The following lines are from "../py/mpconfig.h"

// Whether to support property object
#ifndef MICROPY_PY_BUILTINS_PROPERTY
#define MICROPY_PY_BUILTINS_PROPERTY (1)
#endif

When reporting errors it is helpful to post the complete error message. As well as other interesting information, like which command you used to generate the file.

If it only gives that error for certain MP_QSTR_xxx definitions and not all of them, it means the generation didn't use all needed files/options. MP_QSTR_doc is in objproperty.c, but it is compiled conditionally with #if MICROPY_PY_BUILTINS_PROPERTY. So, likely during your qstr generation MICROPY_PY_BUILTINS_PROPERTY was 0 when the preprocessor ran hence it's not in qstrdefs.generated.h.

Everything I am doing in Windows 10 only. I am not using Linux PC to run any commands. Makefiles are generated automatically for the project.
The following is the error..

Multiple markers at this line
- Symbol 'MP_QSTR_' could not be resolved
- each undeclared identifier is reported only once for each function it
appears in
- 'MP_QSTR_' undeclared (first use in this function)

Errors with MP_QSTR_XXXX

When building minimal, I find that MP_QSTR_ is found near the beginning of the build/genhdr/qstrdefs.generated.h file which looks like this:

Code: Select all

// This file was automatically generated by makeqstrdata.py
  
QDEF(MP_QSTR_NULL, (const byte*)"\x00\x00" "")
QDEF(MP_QSTR_, (const byte*)"\x05\x00" "")
QDEF(MP_QSTR___add__, (const byte*)"\xc4\x07" "__add__")
QDEF(MP_QSTR___bool__, (const byte*)"\x2b\x08" "__bool__")

Please, can you give some clarification here, because I am not able sorting out this problem. I ran .py scripts seperately and added them to my project, but still they are not working.

Consider this:

Code: Select all

//minimal/mpconfigport.h
#define MICROPY_PY_BUILTINS_PROPERTY (0)

//mpconfig.h
#include "mpconfigport.h"
//...
#ifndef MICROPY_PY_BUILTINS_PROPERTY
#define MICROPY_PY_BUILTINS_PROPERTY (1)
#endif

which is what happens for example for the minimal port. Now MICROPY_PY_BUILTINS_PROPERTY is 0, not 1. Just to show that you cannot just look at a single place for figuring out what the value is.

Moreover it's not because your dev environment shows MICROPY_PY_BUILTINS_PROPERTY is 1 when building the project, that it is also 1 when preprocessing during qstr generation. In fact I am pretty sure that exactly is the problem, it's 0 when generating qstrs.
We really can't help you if you do not show exactly what command you are using to generate the header, sorry.

I am not getting "command" from your words. I am using it in Windows 10 and I added MicroPython src code to a new project. I included genhdr/qstrdefs.generated.h file to project before starting building.

[stijn]

The question is how did you create qstrdefs.generated.h? You say you ran .py scripts seperately. Which scripts, what arguments, etc?

[SUBBU3881]

The HighTec IDE don't support Python Scripts Building, So I ran them seperately in Linux PC and added those to my project settings.
can you please give examples to run those scripts.?

[dhylands]

The best way to get examples of how to run the scripts is to due a minimal build on the linux system with make V=1. This is what I see whemn I do that:
