Hello,

It seems you’re encountering a permissions issue when trying to compile your C++ project for the iMX6ULL using Docker. This is likely due to how the volume is mounted and the user permissions within the container. Here are some steps to help you resolve this:

1. Check Volume Mount Permissions:

   • Ensure the directory /home/XXXXXX/test0 on your host has the correct permissions for the torizon user inside the container. You can temporarily set more permissive permissions to test this:

     chmod -R 777 /home/XXXXXX/test0
     

   • If this resolves the issue, adjust the permissions to be more secure, ensuring the torizon user has the necessary access.

2. Verify User and Group IDs:

   • Make sure the user and group IDs match between your host and the container. The torizon user inside the container should have the same UID and GID as your host user.
   • You can specify these IDs in your Docker run command using the --user flag:

     docker run --rm -it -v /home/XXXXXX/test0:/home/torizon/app --user $(id -u):$(id -g) cross-toolchain-arm-test0-container bash
     

3. Check Docker Group Membership:

   • Ensure your host user is part of the docker group to avoid permission issues when running Docker commands without sudo:

     sudo usermod -aG docker $USER
     

   • Log out and back in for the changes to take effect.

By following these steps, you should be able to resolve the permission issues and successfully compile your project for the iMX6ULL target. If the problem persists, double-check your Docker and user configurations.

Need Help adding a precompiled library CMAKE Torizon IDE Project

Hi, I have a relatively simple c project from the Torizon Ide Extension CMAKE template in vscode. I would like to either add a precompiled *.a library, or insert it directly into the project, compile it and link it to the main application. (e.g. an asn1 lib) I now need to know and understand how to get this lib into the container. I suspect by editing the Dockerfile files. For example, let’s say I have a libAsn1Scheme.a file and want to make it available to my main application. I store t…
