Hello,
I’m trying docker for first time, but it is not working for me (via script):
mcnito@mcnito-MINT01:~/Urho3D$ sudo script/dockerized.sh linux rake build install
groupadd: GID ‘0’ already exists
runuser: user urho3d does not exist
Any help?
Thanks!
Follow the instructions on the new website page. You should not use “sudo” at all.
Without sudo:
mcnito@mcnito-MINT01:/media/mcnito/LINUX_DATA/Urho3D$ script/dockerized.sh linux rake build install
Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.24/version: dial unix /var/run/docker.sock: connect: permission denied

See ‘docker run --help’.
I’m following this instructions: Quick Start | Urho3D
Use “podman” which is daemonless or complete the post installation step when continue to use “Docker Engine”. Post-installation steps for Linux | Docker Documentation
Either way you should test run your setup with a simple Docker image before heading back to use the DBE images.
Thanks a lot!
Completing the post installation step worked for me.
I will take a look at podman anyway.
Thanks again.
Hi,
It’s me again…
It worked perfect for linux and web, but on Android its failing:
Starting a Gradle Daemon (subsequent builds will be faster)
FAILURE: Build failed with an exception.

Any help?
Thanks 
Is your Urho3D project root mounted from somewhere else? If so, make sure you have write permission on the “/media/…”. The difference between Android build and other builds is that Android grade plug-in writes all over the places in the project root dir, while the rest just writes into “build/“ relative to the project root.
Thanks a lot again.
I ran script from /home (I will check permisisons later) and it worked (well, bypassed the step).
Now Im getting this error:

Sorry for asking that much, I feel I’m close to the end…
You didn’t say how you ended up in such situation, so it is difficult to pinpoint the exact step that lead to such error. But based on the log, I think the Gradle build process believed it has built the Urho3D library targets and then proceeded to build other dependent targets. They failed because the dependency library was in fact not found. So, I believe your Android build tree is in an inconsistent state. To recover, you could try:
script/dockerized.sh android ./gradlew cleanAll
After that, redo the rake build install using DBE. If the above Gradle “cleanAll” task also gave you error then you will have to clean all the directories generated by Android Gradle plugin yourself. Look for those dir with “.cxx” and “build” using find command and nuke them. Good luck.
Hi,
This not worked. I’ve even tried in a clean Linux Mint installation, with the following commands:
git clone https://github.com/urho3d/Urho3D.git
cd Urho3D
script/dockerized.sh android rake build install
And I still get the same error:

My question is:
Should I try podman?
Should I try on any other Linux Distro?
Thanks!
The same Android DBE image is being downloaded and used over and over again without issue so far. As I understood on how the container technology works, I believe the host operating system has no bearing on your issue. Locally I use “podman” but our CI uses “Docker Engine”, so again you can rule this one out. From the experience I also know that once a docker image is good to run then it would run equally well everywhere. The only thing that I think your host machine could fail the Android build is the amount of memory it has. Since you didn’t paste the whole log, could it be possible that it actually had failed earlier on when building the library target?
You need to have at least 16 GB of memory or more. If you don’t have that many memory in your host then you could scale the Gradle build system down to only build for a single Android ABI at a time, instead of all 4 ABIs in one go (x86, x86_64, armeabi-v7a, and arm64-v8a). You can specify the ABI by using the ANDROID_ABI gradle property like so:
script/dockerized.sh android ./gradlew -P ANDROID_ABI=armeabi-v7a build publishToMavenLocal
You can also tell Gradle to build the target separately.
script/dockerized.sh android ./gradlew :android:urho3d-lib:build
This would just build the Urho3D library alone. So, you can see more easily if it builds OK or not.
Thanks for your help and for being so kind.
I’ve tried this on clean urho3d folder:
script/dockerized.sh android ./gradlew :android:urho3d-lib:build
And this is what i get:

How can i get and share full log?
Thank you.
Since you didn’t answer my question regarding the memory, I will assume your host has enough memory. You can try two things from here:
script/dockerized.sh android ccache -Cz
URHO3D_ANGELSCRIPT build option.URHO3D_ANGELSCRIPT=0 script/dockerized.sh android
Unfortunately currently we have a known issue with the AngelScript subsystem in the master branch that it may produce generated source code with extra large object size when compiled. Still, if you indeed running into this issue then it may mean you actually don’t have enough memory and/or disk space.
Monitor your disk and memory usage while the DBE runs.
Hi again,
Sorry for not replying about the memory. My computer has only 8GB, but I’ve tried this:
script/dockerized.sh android ./gradlew -P ANDROID_ABI=armeabi-v7a build publishToMavenLocal
And gave the same error.
I have also tried this:
script/dockerized.sh android ccache -Cz
and this:
URHO3D_ANGELSCRIPT=0 script/dockerized.sh android
And still failed.
But…
I’ve tried this:
URHO3D_ANGELSCRIPT=0 script/dockerized.sh android ./gradlew :android:urho3d-lib:build
And worked!
But later I’ve tried this:
URHO3D_ANGELSCRIPT=0 script/dockerized.sh android ./gradlew -P ANDROID_ABI=armeabi-v7a build publishToMavenLocal
and this:
URHO3D_ANGELSCRIPT=0 script/dockerized.sh android ./gradlew -P ANDROID_ABI=armeabi-v7a build publishToMavenLocal
And both failed.
Error:

So… does this confirm is a RAM problem? Extending swap partition should fix this?
Thanks, a lot, again
No, this time it might be my fault forgetting to tell you to delete the old build tree first before flipping the “URHO3D_ANGELSCRIPT” build option. Having said that, I think 8 GB is too little for Android build.
Hi,
I’ve tried this:
rm -r Urho3D/
git clone GitHub - urho3d/Urho3D: Cross-platform 2D and 3D game engine
cd Urho3D
script/dockerized.sh android ccache -Cz
URHO3D_ANGELSCRIPT=0 script/dockerized.sh android ./gradlew -P ANDROID_ABI=armeabi-v7a build publishToMavenLocal
And… failed:
Maybe I can try any alternative, If I do an step back, my plan was…
a) linux, for developing → done
b) web, for sharing → done
c) android, for testing real perfomance on device → fail
Find a good IDE for developing and a fast way to test/compile again and again (I think I can make a script that builds linux via docker and runs it locally).
Integrate standard C++ libraries, like AdMob ( 开始 | Firebase ).
Finally, also deploy it for iOS (I know I will have to do it via cmake way).
So, I’m very close to step 2, where I will start to port an abandoned Away3D project.
I dont own a 16GB computer (I can buy RAM, if is the only solution).
Extending SWAP (to 16GB) did not helped.
Do you think that trying podman could help?
Maybe I have docker not installed correctly?
Thanks a lot, any advice would be apreciated.
You just simply need more RAM.
I recall one of the user who got memory issue before reported that increasing the max heap size to 8 GB in the “gradle.properties” file helps. I haven’t verified that personally though. So, take the above advise with a grain of salt. I fixed memory issue with my Android build by putting more sticks into the machine 
Hi @weitjong ,
Sorry for late reply, but until today I had no access to >= 16GB RAM.
Today, a friend gave me RAM sticks and I’ve tried, in a clean Urho3D installation with 20GB RAM, and I get the same error:
If I try:
URHO3D_LIB_TYPE=SHARED script/dockerized.sh android rake build install
or
URHO3D_LIB_TYPE=STATIC script/dockerized.sh android rake build install
or
URHO3D_ANGELSCRIPT=0 script/dockerized.sh android ./gradlew :android:urho3d-lib:build
all of them work, but none of them allow me to build and .apk of my app, also no sample apks are build.
Any help would be appreciated. Im having a lot of fun with Urho3D and Im focused on web deployment now, but anyday I know I will want to make apks.
Thanks a lot.
URHO3D_LIB_TYPE=SHARED script/dockerized.sh android rake build install
This command work on linux mint. On my system 64 GB RAM, but for build was used ~13GB. After first execute I get errors, and I just executed the same command without cleaning and second build was successfully.
Why you use dockerized script?
You can build without docker with this script and environment on linux mint:
# !/bin/sh
export ANDROID_NDK=~/Android/Sdk/ndk/21.0.6113669

Hi,
Thank you for your help.
I’m trying to do EXACTLY as you do, but Im doing something different…:
I think only different thing could be Java version (btw If I use Gradle 6.4 I get other error).
Could you tell me your Java version please?
Thanks a lot!

To save disk space and speedup build you can set the target processor architecture in gradle.properties, for example:
