Can'r compile Android for Moto G

[yagyaxt1068]

I've been trying to build an experimental AOSP Oreo ROM for the Moto G.
I used LineageOS' device tree for the Moto G, and tried to extract the proprietary blobs from it. It shows me these errors:

./extract-files.sh: line 28: ./../../motorola/msm8226-common/extract-files.sh: No such file or directory

I renamed the device tree to msm8226-common, then it shows:

I downloaded Motorola's kernel sources in a zip file and put them in the aosp/kernel/motorola/android_kernel_motorola_msm8226 folder.
I tried to run lunch, but it didn't show up in the menu at first. I made a vendorsetup.sh file to include it, but:

You're building on Linux
