Minimal Build For Linux

Post by Loxy618 » Wed Jul 29, 2020 12:56 pm

Hi All-
I'm trying to build the minimal build for an embedded linux platform. Eventually I'll want to make a static library but for now just trying to get it to compile. In the make file I changed CROSS=0 and left all else the same. I can build and generate the static lib correctly if CROSS=1

It starts off okay and then I get a lot of errors following and it's unclear where to go from here. I'm a little new to this so any help would be appreciated (and also suggestions when I need to build the static lib)

Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity.
mkdir -p build/genhdr
GEN build/genhdr/mpversion.h
GEN build/genhdr/moduledefs.h
GEN build/genhdr/qstr.i.last

Are you compiling on the embedded device, or on your main PC?

FYI you might find https://github.com/micropython/micropython/pull/5964 interesting (I need to finish off a couple of things here but the approach in general is likely to be what's merged).

Can you try removing the "-m32" from CFLAGS and LDFLAGS?
