Cannot compile the code. #3

Open sawaYch opened 5 years ago

The code from Demonstration (actually all projects) cannot be compiled on Ubuntu 18.04. I have already follow the steps in README.md and here is the error message:

error: /usr/lib/gcc/arm-none-eabi/6.3.1/../../../arm-none-eabi/lib/crt0.o: Conflicting CPU architectures 13/1
...
collect2: error: ld returned 1 exit status

Any ideas?

I think I found the solution. It is a bug of libnewlib in version 2.4.0.20160527-3 Compilation success after update the lib to version 2.4.0.20160527-4 Related discussion: https://github.com/bbcmicrobit/micropython/issues/514#issuecomment-404759614

I have another question: cannot flash the program by using openocd. So I tried texane's stlink and it works. Just mention in here for reference, somebody may found it helps. Beware of the format (.hex), if your target is in .bin format then no need to add extra options. st-flash --format ihex write demo.hex

I'm running into this on Mac FWIW.

no way to update libnewlib from what I understand?
