[Devs Needed] Rom compiling issues - Moto Z Play Questions & Answers

I don't know what's the issue with my setup or kernel tree (Alberto97's git) that I'm getting these errors all the time when I try to compile any rom
1) rmnetctl library conflict. There's always this error in all roms and states that "shared libraries is already defined" in rmnetctl folder in device tree hence stopping the build at the begenning. I got past the issue by deleting the rmnetctl folder in device tree but is it the right way to do it?
2) Sepolicy error. Even after I delete above folder, the build stopped after it reaches about 34%, I don't know what it's called but I'm getting this error every time I try to compile any rom. This time while building aosp extended https://hastebin.com/yomepicili.sql
I'm a noob so pardon any lack of knowledge. I am trying to learn to compile here. Also, I'm using oreo-mr1 branch device tree and kernel and oreo-mr1-addison branch for vendor.

[KERNEL][SOURCE][android_kernel_lge_msm7x27-3.0.x (3.0.8)]

I waited to post this over here until it was debugged and all the hardware works.
Even though this forum's been kinda dead quiet for a while, xda gets searched and I want this source code out there.
Derived from androidarmv6 project and tweaked over to thunderc from the p500 developers' awesome work getting it running on the Optimus One.
source:
https://github.com/bigsupersquid/and...7x27-3.0.x.git
(branch squid, for lack of imagination.)
make thunderc-test_defconfig
you'll want to change or remove the toolchain path in the config. it is highly unlikely that your cross toolchain is in the same path as mine.
I set it in the config to avoid having to add "CROSS_COMPILE=/blah/blah/etc" to the make command every time I rebuild the kernel.
it is for jellybean and kitkat roms.
use on older android versions messes up various things. Especially USB.
it conflicts with /sbin/chargerlogo or /sbin/charger for offline charging and bootloops unless that file is removed.
Use the attached removecharger.zip in recovery with signature verification off for that if you don't want to edit the ramdisk yourself.

@bigsupersquid Know if anyone's willing to have a stab at building Firefox OS, now with the 3.x kernel?
EDIT: Well apparently there's no full ArmV6 support in it so, I guess not...

[Q] Building AOSP - Branch 5.0.2_r1 - Boot-loader loop?

Hey XDA!
I've been trying to learn to compile AOSP so I can customize ROM's from scratch instead of having to steal someone else's compile and make modifications from there. I definitely don't want to take the work of others and back track to make changes.
I've got a Nexus 7 2013 LTE and I've setup a Linux build environment. I've installed the correct packages, followed all the instructions on the AOSP site, and downloaded the proprietary binaries (both the current 4.4.4 and preview binaries) to try and create a AOSP Lollipop 5.0.2_r1 build. I know there are ones out there that are working almost flawlessly, but I can't seem to get it to boot. My file sizes for system.img and all other packages are the same after compiling, I "make clobber" once executing the shell scripts to create the vendor folder in my source root, and I see the vendor files being processed during the build, but once the package (both ota and manually built attepts) are fastboot loaded, I get a boot loop, and I'm not sure why, it instantly hangs and reboots as soon as the "ANDROID" screen appears.
If anyone can give me any guidance, I want to start building ROMs for the community, but I just can't seem to get a bootable build to compile.
I may have missed some details, so if anyone can help me with figuring this one out, feel free to PM me, or leave a note on this topic.
Thanks!

Build Issues with aosp source

So I have been trying to get a functional build of this devices kernel for a while now and I have to say it sucks.
My first problem was finding the actual kernel source which isn't on the aosp site but rather in the chromium source. When I finally found the kernel source for it, I was greeted with an absurd amount of branches. I mean aosp has like 6 branches for a device after 4 or so years and this device has countless branches referencing its multitude of names (pixel c, ryu, smaug, and dragon). Anyways I decided to pick the chromeos-3.18 branch (https://chromium.googlesource.com/chromiumos/third_party/kernel/+/chromeos-3.18) not sure if this is right. Then I spent forever looking for a fitting defconfig which there was none, only to find you have to run a script with the right flavor and device to create the defconfig. I finally got that done and got a dragon_defconfig that let me build a kernel binary.
Here is where I am stuck. So before I went to substitute this binary in the boot image I just wanted to try making a boot image with the stock provided kernel.
I was able to build using "make bootimage" and got a boot image that sent me into a bootloop. And this is with the 6.0.1r16 branch with no modifications. I looked into the dragon-kernel and noticed the provided kernel file is a file called Image.fit which is the first time seeing such a file format. The kernel binary I created was just an "Image" and a compressed version "Image.gz" but neither is anything like the Image.fit file that is provided.
Either way I am really stuck and the lack of documentation pertaining to the pixel kernel source is frustrating. Can anyone help me out?

Error MK8080B Plus own device tree

After a lot of googling around and like 50 open chrome tabs I tried making own device tree so I used old cm makedevice.sh script and updated it with help of current lineage bacon device tree and some brcm_rpi3 device tree, here you go *"*"https://github.com/honzapatCZ/android_device_amlogic_mk8080bplus"*"* vendor is not currently setup so Iam building just recovery, but I get an error:
HTML:
23:00:34 Could not create module-finder: finder encountered 1 errors: [/mnt/d/Dev/ANDROID/lineage/android/lineage/external/swiftshader/tests/unittests: lstat /mnt/d/Dev/ANDROID/lineage/android/lineage/external/swiftshader/tests/unittests: no such file or directory]
Any idea what it is? How to fix it? Iam gonna do more research about rpi3 device tree as its the closetst thing I know about features.
Thanks

Unofficial build help?

I'm trying to build for a device that has no known Android 10 device trees that I can find. I think I fleshed out the trees pretty well by following some sister/cousin devices and extracting a lot of stuff from the rooted phone itself, but my build fails at 2% due to a missing output file. The missing libdss.so file should be built as part of the kernel (whose source I have), but the build clearly isn't happening (or isn't happening in time to be recognized by the build system.)
I tried to build the kernel as a standalone module to see what might be wrong, and in trying to do that I can't seem to resolve all the issues with dependencies for cross-compilation to arm64. I've built for devices with existing trees by cherry-picking what I needed, but I've never built for something from the ground-up like this. I don't want to make the ROM with a pre-built kernel as the end-goal would be to become official. The attached image is the exact error I'm receiving, and the following links are to all of my source repositories that I'm using in addition to the Lineage17.1 base. Any help would be appreciated. I work as a full-time dev by day, I don't mind slogging around in some code if that's what I takes, I've just reached the end of my troubleshooting knowledge here and am not sure what the next step might be.
