Problem when starting Cooja simulator #2848

Open dfonovic opened 10 months ago

dfonovic commented 10 months ago

I got this error when I try to start Cooja simulator from Docker conatainer:

root@9e6c9da70970:~/contiki-ng# cooja Starting a Gradle Daemon, 1 incompatible and 1 stopped Daemons could not be reused, use --status for details

FAILURE: Build failed with an exception.

Use the user user inside the container, not root.

I have the same error with the user:

Might be related to Java 21 being the default, while Gradle 8.1.1 only supports Java 20.

The Java 21 issue with Gradle 8.1.1 sounds plausible, try with an older contiki-ng image and see if that works better.

yvshudrenko commented 4 months ago

Recent images had the same issue, tried one randomly from a bit longer ago - 8f38c24bc0c292a0115b36eb9aad1efa4dddfd5aeecc12693c30cc170fc65a54, it works. There are still some hiccups related to X11 with M1 Mac, but it's a different story.

Not sure what's the deal here in general with macOS, seems to work fine on WSL with latest contiki image.

I am trying to get cooja running on linux using docker. I followed the getting started guide to install the docker image. I tried with contiker/contiki-ng:latest , and some older images, including 8f38c24bc0c292a0115b36eb9aad1efa4dddfd5aeecc12693c30cc170fc65a54. None of them works for me.

On the contiker/contiki-ng:latest I get:

Java version in this container is:

user@ec36d7b5ed99:~/contiki-ng/tools/cooja$ java -version
openjdk version "17.0.7" 2023-04-18
OpenJDK Runtime Environment GraalVM CE 17.0.7+7.1 (build 17.0.7+7-jvmci-23.0-b12)
OpenJDK 64-Bit Server VM GraalVM CE 17.0.7+7.1 (build 17.0.7+7-jvmci-23.0-b12, mixed mode, sharing)

Is the problem really related to the java version?

Am I doing something wrong to start cooja from the container? Do I have to do/configure something else?

Any help appreciated.

@tenllado for some reason, your container cannot find services.gradle.org. I can download https://services.gradle.org/distributions/gradle-8.10-bin.zip just fine on my machine, so your problem has nothing to do with the Java version. It's also unlikely to be a Cooja bug, I suggest looking into DNS- or firewall-settings on the host machine.

tenllado commented 1 month ago

@pjonsson thank you so much, you are right, it is a problem from the container. I solved it using 8.8.8.8 as dns for dockerd but now it rises an error when opening the window:

...
Authorization required, but no authorization protocol specified
Exception in thread "main" java.awt.AWTError: Can't connect to X11 window server using ':0' as the value of the DISPLAY variable
...

I am running the container with the recommended command in the getting started guide:

docker run --privileged --sysctl net.ipv6.conf.all.disable_ipv6=0 --mount type=bind,source=$CNG_PATH,destination=/home/user/contiki-ng -e DISPLAY=$DISPLAY -e LOCAL_UID=$(id -u $USER) -e LOCAL_GID=$(id -g $USER) -v /tmp/.X11-unix:/tmp/.X11-unix -v /dev/bus/usb:/dev/bus/usb -ti --rm contiker/contiki-ng

I am sure it is a problem of alowing docker to open windows, just I do not know what to do. I am using gnome3 with wayland, just in case that matters. Any help would be appreciated. Thanks.

For anyone interested, the solution was to run before the command xhost +SI:localuser:$(id -un).
