A lot of qstr undeclared when compiling ulab

[bhcuong2008]

Hi,
I set up my own environment to build micropython 1.24 ESP32 IDF 5.4 together with micropython-ulab 6.6.1. I set CMake variable USER_C_MODULES following the guide. It has a lot undeclared qstr as below. I've checked genhdr/qstrdefs.generated.h, and all these qstr in there. Please help me how to resolve this.

micropython/cmodules/ulab/code/numpy/approx.c:55:11: error: 'MP_QSTR_left' undeclared (first use in this function);
micropython/cmodules/ulab/code/numpy/approx.c:56:11: error: 'MP_QSTR_right' undeclared (first use in this function);

micropython/cmodules/ulab/code/numpy/random/random.c:25:23: error: 'MP_QSTR_normal' undeclared here (not in a function);
...

In file qstrdefs.generated.h, it has entry QDEF1(MP_QSTR_left, 19934, 4, "left"). In Micropython 1.21, esp-idf-3.3.5, I built it succesfully, it has QDEF(MP_QSTR_left, 19934, 4, "left"). It is different between QDEF and QDEF1.

Thanks.

Make sure you start with a clean build after changing options, as the QSTR generation is not done on every build. make clean BOARD=...

I've deleted the whole build directory many times but these errors still occurs. I built with CMake system in IDF v5.4.

I found it due to my mistake. I create another folder with the same name genhdr, so it could not found qstr in qstrdefs.generated.h.
