make error on build - Githubissues

GiovanniCardamone commented 3 years ago

Hello, i was trying to build a low.js bin on my machine

$ uname -a
Linux Jhos 5.4.0-58-generic #64-Ubuntu SMP Wed Dec 9 08:16:25 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

but the make command gave me the following error:

$ make

someone know how to fix this?

My guess: python most probably links to v3, but you must have v2 installed for DukTape.

GiovanniCardamone commented 3 years ago

yep, my python executable links to python3.7

$ python --version
Python 3.7.7

i will replace makefile python with python2 executable

$ python2 --version
Python 2.7.18

Tips:

maybe makefile should have variable like CC for python?

example:

PYTHON2=/path/to/python2
