I’ve looked at the wiki for building /e/ for phones that aren’t officially supported, but it only works (without modification) for phones that have official LineageOS builds.
I found an unofficial LineageOS build for the Pixel 2.
If someone could walk me through/point me to a resource on how to use this LineageOS ROM to build /e/ for the Pixel 2 (walleye), I would appreciate it.
Hi @wilson did you get a chance to have a look at this post by @andrelam
It has a script which can be modified for your build requirements.
Click here for non lineage supported devices.
Ok @andrelam, I was able to look at your post and found the kernel and device files for the Pixel 2 on the XDA post I initially linked. There is this website that has vendor images for the Pixel 2 directly from Google. Do I need both the vendor image and the Qualcomm file?
I don’t know what you mean by Qualcomm file. So you don’t have vendor “sources”, only vendor.img? I never tried building without vendor. I guess it could work. But you’d have to flash vendor.img after you flashed /e/.
There are two .tgz files that I extracted and contained a lot more walleye-related files. Honestly, I feel I am quickly getting above my technical ability.
I would try the sources mentioned in the XDA thread. And use this for vendor: https://github.com/TheMuppets/proprietary_vendor_google/tree/lineage-16.0/walleye Then it should work. I don’t know why they use 2 device sources, maybe you need both, don’t know.
Ok, I used the vendor files you suggested. After setting up the build script I’m getting the error “fatal: Couldn’t find remote ref refs/heads/pie”.
I know /e/ is just now building Pie out for a few phones. If you can provide some help, great. If not, that’s fine too.
Change branch name to v1-pie
I was able to do that and got the build script to run until it filled my root partition on my Ubuntu install, over 100 GBs!
Is it expected that it will take up that much disk space? If so, is there a way to force the build onto another disk (my /home is on a separate 750 GB HDD, while / is on a 120 GB SSD)?
Yes it’s about 250Gb i think, depends on what you download. just create a structure where /srv/ and /root/ points to you bigger drive.
I modified the build script to point to my larger /home directory and it seems to have downloaded all of the necessary sources. I got some error messages about the makefile for lineage_walleye not existing (see below) when it tried to build:
build/make/core/product_config.mk:234: error: Can not locate config makefile for product "lineage_walleye".
03:00:30 dumpvars failed with: exit status 1
build/make/core/product_config.mk:234: error: Can not locate config makefile for product "lineage_walleye".

I at least partially answered my own question. Since the kernel reference for the Pixel 2 is “wahoo”, not “walleye”, I had to change my roomservice.xml file to reflect that. I still got an error when building but am trying a few other possibilities.
@andrelam, here is the output (including errors) I get after changing roomservice.xml:

What Linux version do you use? It’s missing libtinfo.so.5 Did you use the builde.sh script from GitHub?
@andrelam I’m using Ubuntu 19.04. I was using an old version of builde.sh, so I updated to the GitHub version. The build went for a while but eventually failed with this output

@andrelam, thanks to all of your help I was finally able to build /e/ for the Pixel 2. I will install it in the next few days and report back. Hopefully I will be able to post my unofficial build soon
Hi @wilson good to hear that you were able to build your own ROM. Nothing beats the pleasure of watching a ROM you built running on your own phone 
Good job, hope all is fine.
