AOSP version 11 build on Ubuntu 18.04 failed (getting segfaults)

I tried to build AOSP using the following commands:
repo init -u https://android.googlesource.com/platform/manifest -b android-11.0.0_r27
repo sync
. build/envsetup.sh
lunch aosp_x86_64-eng
make -j8
It runs for about 1.5 hours before erroring out. Here is what I see in the log:

My system has 64 gb of RAM and I tried lowering the j value but get the same results. Repo sync is successful.

I'm not an usual contributor to S/O but I spent a lot of time fixing this particular problem for someone so I thought it'd be nice if I gave you my solution for this.
zipinfo is likely crashing because there is a preloaded library called libAppProtection, installed in /usr/local, that crashes under the conditions imposed by the AOSP build. I had found a workaround for this particular problem but if the cause of the problem is the same as what I faced, you will have further problems down the line for which you won't find a workaround.
GDB stacktrace of 'fec' another program crashing the same way
In Firefox shows only blank pages - even about:config is just white it describes that the library is related to Citrix Workspace App SDK.
If you observe the same thing I did when running zipinfo or fec (in my case) with GDB, I can only recommend that you remove this program while you deal with building the AOSP sources. I know this has worked and did not cause any drawbacks for the client. Maybe just disabling the preloaded library in /etc/ld.so.preload would work but I have not tried that and since I don't know anything about Citrix, I would advise against doing that.

Creating APK from Kivy on Mac OS X fails after compile

My background is in HTML/JS, so compiling is new for me. While attempting to build my python project in Kivy to an Android .apk, I am getting an error I do not understand:
Command failed: ./distribute.sh -m "kivy"
Here is a portion of the tail end of the debug output...

OK, I came across the answer to my own problem a while ago and I'm posting it here in case someone else makes the same boneheaded mistake. Basically, I did not read the instructions carefully enough in the documentation. The instructions clearly state "navigate to your project directory and run: buildozer init". I did not navigate to the project folder. I was building in my user directory, hence "/Users/Travis/". Hence the "No such file or directory" error.
You may be asking "How do you expect buildozer to know where your project is?"
Well, the next step says to configure "buildozer.spec", and in there, there is a place to put your path to the main.py, which by default is ".", so I changed that. It actually worked up to the point that it has to write any files.
So, if you're having the same issue as me, you might just need to read more carefully.

GCC thinks I'm running x86

I am trying to compile Cyanogenmod on Linux Mint 15. And receive the following error.
host StaticLib: libmincrypt (/home/benji/Source/out/host/linux-x86/obj/STATIC_LIBRARIES/libmincrypt_intermediates/libmincrypt.a)

ERROR: ./../../gcc/linux-x86/host/x86_64-linux-glibc2.7-4.6/bin/x86_64-linux-gcc only run on 64-bit linux
I can't figure out what is causing this. I am on a 64 bit install. Please advise.
benji#ultranoid ~/Source $ uname -p
x86_64

Workaround
Comment out lines 23-38 of prebuilts/tools/gcc-sdk/gcc
Example: http://pastebin.com/qH0BYcSF

As pointed out here, within Android build system the test for x32 vs x64 host is based on the output of file -L "$SHELL" | grep -q "x86[_-]64". In other words it tests whether or not current shell is a 64 bit binary.
So a possible answer is : check out if value of environmental variable $SHELL is a valid path to a shell executable.
You may try to change shell with chsh or
create a link to your favorite shell so that $SHELL is satisfied. The latter did the trick for me - I've simply linked /bin/bash to where $SHELL pointed.

use uname -m to check system.
#file -L "$SHELL" | grep -q "x86[_-]64"
#if [ $? != 0 ]; then
# $SHELL is not a 64-bit executable, so assume our userland is too.
# echo "ERROR: $MY_TOOL only run on 64-bit linux"
# exit 1
#fi
changed to:
ARCH_OS=uname -m | tr '[:upper:]' '[:lower:]'
if [ "$ARCH_OS" != "x86_64" ] ; then
echo "ERROR: $MY_TOOL only run on 64-bit linux from uname -m"
exit 1
fi

How do you create a loadable kernel module for Android?

I know there a number of walkthroughs and tutorials floating around out there which describe this activity, but after having read many of them I still can't get this working. If anyone has the patience to wade through the steps I've taken (posted below) and suggest where I may have gone off track I'd be very appreciative. I've spent about a day and a half staring at make files and reading walkthroughs so literally any suggestions would be helpful.
Environment:
I'm using an Ubuntu 10.04 32 bit vm.
I'm hosting from a 64 bit windows 7
My Core 2 Duo does not have the hardware support for 64 bit VMs so i'm trying to compile against Android 2.1 kernel
I have installed Java 1.5 from the Dapper repo and removed my 1.6 installation
The rest of the tooling has been acquired according the Android dev documentation...
As per Initializing a Build Environment:
Java:
$ sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu dapper main multiverse"
$ sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu dapper-updates main multiverse"
$ sudo apt-get update
$ sudo apt-get install sun-java5-jdk
Other required:
$ sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev libc6-dev libncurses5-dev x11proto-core-dev libx11-dev libreadline5-dev libz-dev libgl1-mesa-dev
$ sudo apt-get install gcc-multilib g++-multilib libc6-i386 libc6-dev-i386
Then from Downloading the Source Tree:
Repo:
$ mkdir ~/bin
$ PATH=~/bin:$PATH
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo
$ mkdir WORKING_DIRECTORY
$ cd WORKING_DIRECTORY
$ repo init -u https://android.googlesource.com/platform/manifest -b eclair
$ repo sync
$ gpg --import (imported the huge key)
And from Building the System:
Initialize:
$ source build/envsetup.sh
Choose a Target:
$ lunch generic-user
Build the Code:
$ make -j4

So it turns out i've got some problems here. I assume that once i've overcome these issues, i'll have an environment capable of compiling kernel modules. Please do correct me if I'm wrong.
Next I head into my directory containing my module.c file and it's makefile. Contents of makefile below:
obj-m += mymodule.o
CROSS_COMPILE=~/WORKING_DIRECTORY/prebuilt/linux-x86/toolchain/arm-eabi-4.2.1/bin/arm-eabi-
KERNEL_DIR ?= /home/<myuser>/WORKING_DIRECTORY
VERSION = v1.1
all:
make -C $(KERNEL_DIR) M=$(PWD) ARCH=arm CROSS_COMPILE=$(CROSS_COMPILE) modules
rm -rf *.c~
rm -rf *.mod*
rm -rf *.o
clean:
make -C $(KERNEL_DIR) M=$(PWD) clean
I have very little experience with make and makefiles, but this looked reasonable to me. My main concern with this file is the KERNEL-DIR variable. I tried a few different values for that variable, but got all sorts of errors where I do not with it's current value. Of course, it could still be wrong, so any comments here are welcome.
So, as far as I know, I should be able to execute make with no args or anything and will figure out what it needs to do. I have tried make, make -f both with and without sudo. All four permutations yield the same results:
make -C /home/<myuser>/WORKING_DIRECTORY M=/home/<myuser>/Desktop/<MyModuleDir> ARCH=arm CROSS_COMPILE=~/WORKING_DIRECTORY/prebuilt/linux-x86/toolchain/arm-eabi-4.2.1/bin/arm-eabi- modules

You'll notice a few screwy warnings, but as best as I can tell, they are not real problems. If anyone feels differently about these, please say so.

I guess that last line sounds pretty suspicious but I have no idea what to do about it. Apart from the few strange things i've mentioned, it would appear that this all went smoothly. However, after the whole thing completes, I can't find the *.ko file anywere. I did a ls -alRg | grep *.ko on my home directory and it turns up nothing. I'm stumped. If I can provide any more information or run any tests or try anything differently i'll be checking in frequently.

Sorry for being late, but hope it helps:
http://tthtlc.wordpress.com/2011/12/29/how-to-write-a-kernel-module-on-android-sony-ericsson-xperia-arc-s/
I wrote and tested the code on my Sony Ericsson Xperia Arc S and it works (in general in should work for any Android phone).
Connecting via adb and USB, and “su” to root, the “lsmod” listed all the kernel module (in general, the article at
http://web.archive.org/web/20121106004141/http://developer.sonymobile.com/2011/05/06/how-to-build-a-linux-kernel gave a very good coverage of what to do in Linux kernel compilation for SonyEricsson phone):
lsmod
android_module 654 0 - Live 0x7f007000 (P)
sdio 16532 0 - Live 0x7f000000
“android_module” was the one I had inserted via insmod android_module.ko.
Here’s how to do it:
First the original program was copied from:
http://rechtzeit.wordpress.com/2011/03/21/77/
Or reproduced as follows:
android_module.c:
#include"linux/module.h"
#include"linux/kernel.h"
//replace the "" with angular brackets
int init_module(void)
{
printk(KERN_INFO "Hello android kernel...\n");
return 0;
}
void cleanup_module(void)
{
printk(KERN_INFO "Goodbye android kernel...\n");
}
Makefile:
obj-m += android_module.o
all:
make -C /home/tteikhua/android/sony_ericsson_src/58/kernel/ M=$(PWD) modules
clean:
make -C /home/tteikhua/android/sony_ericsson_src/58/kernel/ M=$(PWD) clean
The directory where the kernel is located (“-C” above) is where kernel is located.
And the following command will use the Makefile from above:
ARCH=arm CROSS_COMPILE=/opt/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi- make
As shown above, the cross compiler I had used is from CodeSourcery.
And after insmod android_module.ko you can see the debugging message in dmesg output:

And the “Goodbye” is when rmmod android_module is executed. In between are debugging message from other components in the kernel.
Final words:
The above are written in 2011, for more modern resources, please refe to the following to get started:
https://source.android.com/docs/core/architecture/kernel/modular-kernels

I think I've red that emulator kernel does not support module, so you must compile also the kernel with modules support.
I hope that this link will help you

There are two things you'll need to do. Firstly, create an emulator kernel that supports loadable kernel modules.
There's a comprehensive post here covering the process of setting up the emulator kernel.
There are 2 parts of the instructions to alter:
I find it easiest to keep the kernel within the repo area (in this case, ~/WORKING_DIRECTORY), like so:
cd ~/WORKING_DIRECTORY
mkdir kernel
cd kernel
git clone git://android.git.kernel.org/kernel/common.git
The branch information is no longer correct, however, so where it says:
git checkout -t origin/android-goldfish-2.6.29 -b goldfish
use this instead:
git checkout -t archive/android-gldfish-2.6.29 -b goldfish
As you've found out, the kernel by default is not configured with loadable module support. Enable before compiling. After, this step:
make ARCH=arm goldfish_defconfig
do this:
make ARCH=arm menuconfig
A text-based menu will show up. Use the Up/Down arrow keys to navigate, Space to select an option, Enter to expand a menu (menus have --->) at the end of the line, and Esc-Esc to go back a menu.
Select "Enable loadable module support" by scrolling down and hitting Space
Hit Esc-Esc to exit, and hit Enter to save the new configuration
Now build. Using your setup, it would be:
make ARCH=arm CROSS_COMPILE=/home/<myuser>/WORKING_DIRECTORY/prebuilt/linux-x86/toolchain/arm-eabi-4.2.1/bin/arm-eabi-
Now that that's done you can do the second part, which is making a loadable kernel module. You were almost there, but because you didn't have the kernel source for the emulator, it didn't work. Just take the makefile you have and change KERNEL_DIR to:
KERNEL_DIR ?= /home/<myuser>/WORKING_DIRECTORY/kernel/common

color the lines of logcat on Linux [android]

The Logcat in Eclipse has colors for errors, warning, debug, ...
How can I do to get the same result on Linux (Ubuntu) when I run the command 'adb -e logcat' in a terminal to get it colored?

adb logcat -v color
from developer.android.com

Link with script
I think it will be useful for you and you can change script by yourself;)

This is my view of "colorizing" the logcat:
https://bitbucket.org/brunobraga/logcat-colorize

My favourite is pidcat, maintained by Jake Wharton based off of Jeff Sharkey's script (mentioned by Yaroslav Boichuk).
I have also used logcat-color, maintained by Marshall Culpepper, (also based off of Jeff's script) which allows you to create profiles you can activate (log per task, or per application, etc).
I have preferred pidcat because at the time logcat-color wouldn't filter by package name, and I never went back to try again once it was added. Seems to be reasonably popular still as well.

And yet another script:
#!/bin/sh
while :; do
adb $# logcat | sed \
-e 's:^V/:\x00\x1b[0;35m:g' \
-e 's:^D/:\x00\x1b[0;36m:g' \
-e 's:^I/:\x00\x1b[0;32m:g' \
-e 's:^W/:\x00\x1b[0;33m:g' \
-e 's:^E/:\x00\x1b[0;31m:g' \
-e 's:^F/:\x00\x1b[0;31m:g' \
-e '/Unexpected value from nativeGetEnabledTags/d' \
-e '/The application may be/d'
sleep 1
done

If you use Python, PyLogAnalyser can filter, colorize and analyse all type of logs in Linux, Windows and Mac (and Cygwin).
You can install it directly from PyPI:
python -m pip install pyloganalyser
And call it in order to print the log for the standard output (also, for text or HTML output):
adb logcat -v threadtime | python -m loganalyser --stdin --stdout -c Android_logcat_threadtime.conf
The file 'Android_logcat_threadtime.conf' is included in the module directory. So the actual invocation could be:
CONFPATH="$(python -c 'import loganalyser;print loganalyser.__file__.replace("/__init__.pyc","")')";
adb logcat -v threadtime | python -m loganalyser --stdin --stdout -c "$CONFPATH"/android/Android_logcat_threadtime.conf
Website: http://pyloganalyser.sourceforge.net

Have a try with lnav , add logcat config from here
