Will not compile with module #147

Closed RaspberryPiDude314 closed 1 year ago

Hi all, fairly new to building Micropython from source. I've tried every variation of make -C ports/rp2 BOARD=RPI_PICO_W USER_C_MODULES=/home/pi/pico/st7789_mpy/micropython.cmake I can think of but no matter what, it does not compile with the library. While it does build, the library just isn't present. It seems to just ignore it whatever I do. Help is much appreciated!

What version of MicroPython are you trying to compile?

russhughes commented 1 year ago

I used:

make -C ports/rp2 BOARD=RPI_PICO_W USER_C_MODULES=/Volumes/MicroPython/st7789c/micropython.cmake

And it was successful. You should be able to find the following lines in the make output:

Including User C Module(s) from /Volumes/MicroPython/st7789c/micropython.cmake
Found User C Module(s): usermod_st7789

If they don't appear, the module source is not being found.

I did eventually locate the problem- due to some bug with the compiler, it will not re-check for external c modules since the last build in that directory. After figuring this out, all O had to do was run make clean and make it again and it worked as intended. There's unfortunately not much information about this bug but that was the problem.
