Build failure for raspberry PI 4 #5992

Closed waqas-shafique closed 2 years ago

waqas-shafique commented 2 years ago

CircuitPython version

circuitpython-7.2.0-alpha.1

Code/REPL

It looks like the error message is originating from

if not qcfgs:
        sys.stderr.write("ERROR: Empty preprocessor output - check for errors above\n")
        sys.exit(1)

Behavior

make BOARD=raspberrypi_pi4b Use make V=1, make V=2 or set BUILD_VERBOSE similarly in your environment to increase build verbosity. ERROR: Empty preprocessor output - check for errors above make: [../../py/py.mk:269: build-raspberrypi_pi4b/genhdr/qstrdefs.enum.h] Error 1 make: Deleting file 'build-raspberrypi_pi4b/genhdr/qstrdefs.enum.h'

It builds OK for me -- did you install everything as in this guide https://learn.adafruit.com/building-circuitpython?

waqas-shafique commented 2 years ago

@jerryneedell verifying all steps again, will update you shortly

I tried all steps again with a fresh clone of the repo but the same result as before.

I tried to build another board using make BOARD=circuitplayground_express and it builds fine.

However, for make BOARD=raspberrypi_pi4b I'm getting the same error i.e.

GEN build-raspberrypi_pi4b/genhdr/mpversion.h python3 ../../py/makeversionhdr.py build-raspberrypi_pi4b/genhdr/mpversion.h GEN build-raspberrypi_pi4b/genhdr/qstrdefs.enum.h python3 ../../py/makeqstrdata.py build-raspberrypi_pi4b/genhdr/qstrdefs.preprocessed.h > build-raspberrypi_pi4b/genhdr/qstrdefs.enum.h ERROR: Empty preprocessor output - check for errors above make: [../../py/py.mk:269: build-raspberrypi_pi4b/genhdr/qstrdefs.enum.h] Error 1 make: Deleting file 'build-raspberrypi_pi4b/genhdr/qstrdefs.enum.h'

Also git describe --tags command shows below result 7.2.0-alpha.1-343-gfd2cbc00f

Debugging this in discord. The aarch64 toolchain was missing, but it wasn't obvious from the errors above. Perhaps there should be an earlier more obvious check for the toolchain existence.

Also having trouble due to mkfs.fat v4.1 not having --offset arg. Need v4.2, which is not immediately available for Ubuntu 20.04.
