Unable to make

[sluthra1]

Hello I am trying to make the flow library on my MacBook, I've installed the toolchain. I am able to compile PX4, but when I run make on the px4flow firmware libraries I cannot complete the make. The first problems were with python incompatibilities (mode 'rob' and cString vs io.bytesIO), but now with those resolved I get the error":

Flow/Tools/make_can_boot_descriptor.py", line 283, in
out_image.write(bootloader_image)
TypeError: a bytes-like object is required, not 'str'

This is a problem of compatibility between python 2 and python 3. I fixed it in PR #96 .

The relevant changes are in dd2425b

Hi @jlecoeur ,
I got the following problem:

How do I fix it?

@EdXian this is a different problem, please open separate issues in this case.

Your problem is that your compiler version is not allowed, you can either:

• install one of the versions suggested in the error message
• add 7.2.1 near line 57 of file src/Flow/makefile/baremetal/toolchain_gnu-arm-eabi.mk

Python vs Python2 issue was fixed in 8fa8fdc.
The default compiler version on Ubuntu 18.04 is 6.3.1, so 7.2.1 is a bit too new, maybe will get tested and added later.
