Hi,

I'm trying to build the project as written in the readme but I have trouble executing the make -j8 command

Here is the output:

I'm not really used to make and makefiles so I don't know what to do then. Any help would be appreciated.

Thansk!

I've met the same issue, could someone help us out?

The issue is solved by compiling with python 2.7.
