Trying to build unofficial 15.1 - Motorola Droid RAZR

Right now, i'm trying to build los15.1, just for fun (i'm not using this smartphone at all, but i want to learn how to do a bring up, it's interesting). I've fixed about 11 compile time error (missing libs etc), but i have other, such as:
Code:
system/core/adb/daemon/main.cpp:113:59: error: use of undeclared identifier 'AID_UHID'
AID_NET_BW_STATS, AID_READPROC, AID_UHID};
^
system/core/adb/daemon/main.cpp:114:49: error: no matching function for call to 'ArraySizeHelper'
minijail_set_supplementary_gids(jail.get(), arraysize(groups), groups);
^~~~~~~~~~~~~~~~~
If someone knows how to fix it, let me know! Here's is my roomservice.xml:
Code:
<?xml version="1.0" encoding="UTF-8"?>

UPDATE:
I have compiled android 8 (thx to @stargo for the last patches) but i can't flash it without a new and updated recovery...i will let you know (if there's still someone with this device lol)

---

I have back-ported the kernel (binder, alarmtimer etc) with di help of @Tomoms . Then, i've reimplemented file-based flash and i've commented device and selinux assertion in updater-script (because they don't work on this old twrp with 8.0 rom). But there's something that i'm missing, because the rom won't boot, and it goes on AP fastboot (the new kernel works on los14.1, obv with CONFIG_ANDROID_BINDER_IPC_32BIT=y, while on los15.1 it must be on =n)
My sources: https://github.com/feduss/android_kernel_motorola_omap4-common

Sorry, but i failed and i give up for now....there are a lot of complex errors during boot process. I'm attaching here my manifests (you can find my changes in my git repos) and the log, in case somebody wants to give it a try.

远在中国的我表示很喜欢这个设备,现在它运行起来很慢,不过作为第二个设备很好值得研究,但是我更敬佩你对这个设备的支持与付出。我还是偶尔会上这论坛看看的。
