VAR-SOM-MX6 - Android Nougat N7.1.1 - Common errors


1 Code fetch errors

These errors might occur when a repo sync command is unable to fetch the code from the repo manifest.
Output example:

Fetching project platform/external/linux-tools-perf

error: RPC failed; result=56, HTTP code = 200 625.00 KiB/s

Receiving objects: 100% (192/192), 282.68 KiB | 53.00 KiB/s, done.
Resolving deltas: 100% (33/33), done.

How to fix these errors:

  • Make sure you are not behind a firewall that is blocking your access to the relevant repositories (if needed, contact your IT administrator about this).
  • If you want to use a proxy you should set the following environment variables before running the repo command:
$ export HTTP_PROXY=http://<proxy_user_id>:<proxy_password>@<proxy_server>:<proxy_port>
$ export HTTPS_PROXY=http://<proxy_user_id>:<proxy_password>@<proxy_server>:<proxy_port>

More rarely, Linux clients experience connectivity issues, getting stuck in the middle of downloads (typically during "Receiving objects"). It has been reported that tweaking the settings of the TCP/IP stack and using non-parallel commands can improve the situation. You need root access to modify the TCP setting:

$ sudo sysctl -w net.ipv4.tcp_window_scaling=0
$ repo sync -j1
  • Make sure you have sufficient free space available on your machine before you start any repo sync
  • Make sure you have initialized the host machine build environment is initialized correctly.

2 Build Errors

2.1 Jack Server Errors

Usually, jack server errors are common starting from Android 7.1.1 onwards, if not sufficient RAM memory or ownership of the jack server is controlled by other users/jack server use.
Refer to https://source.android.com/setup/build/jack#using_jack to jack documentation to understand why JACK server exists.

  • Fix:
Try increasing your swap space or increase your maximum RAM available in your system keeping 1 GB for your system to work properly. We recommend you have at least 16GB and 32 GB swap space.

Otherwise, you will end up in such a situation. https://stackoverflow.com/questions/35579646/android-source-code-compile-error-try-increasing-heap-size-with-java-option
Assuming you have 16 GB of RAM below are the commands you can run before starting compilation.
Please don't clean the system, it will take more time again to compile it.

$export JACK_SERVER_VM_ARGUMENTS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx15000m"
$out/host/linux-x86/bin/jack-admin kill-server
$out/host/linux-x86/bin/jack-admin start-server

And restart the build.

2.2 Multiple user jack errors

Jack server runs system-wide only once, so if you have multiple users building android, make sure no previous build was running and no other jack servers are running. To verify run

$ ps -afx | grep "jack-server"
 612 pts/11   S+     0:00                      \_ grep --color=auto jack-server
27543 pts/10   Sl     8:48 java -XX:MaxJavaStackTraceDepth=-1 -Djava.io.tmpdir=/tmp -Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx15000m -cp /home/user/.jack-server/launcher.jar com.android.jack.launcher.ServerLauncher
  • Fix:

If you see the process like that kill it, as the only tired compilation by the only single user is allowed.

$ sudo kill -9 27543 

Note: In the above case 27543 is PID of the jackserver running as an example. And then restart the build normally

2.3 Flex Errors

FAILED: out/target/product/xxx/obj/STATIC_LIBRARIES/libedify_intermediates/lexer.cpp 
/bin/bash -c "prebuilts/misc/linux-x86/flex/flex-2.5.39 -oout/target/product/xxx/obj/STATIC_LIBRARIES/libedify_intermediates/lexer.cpp bootable/recovery/edify/lexer.ll"

Aborted (core dumped)

If you encounter above flex assert errors or building on Ubuntu 18.04 with older Flex version from prebuilt, this is highly likely you will encounter above error. Please use below command to export env variable

$ export LC_ALL=C

And restart the build.
