vitis_setup.sh with non-root permissions

[linux-guy-217]

We are attempting to run the vitis_setup.sh script in a managed environment which already has all of the pre-reqs (Vivado, Vitis, python, etc) installed and available, but we don't have root access to the host.

Is there an alternative way to source this vitis_setup.sh script without the requirement for root level access?

Dear customer

You need sudo permissions if you do not have all the required packages referred to in vitis_setup.sh script, to install the required packages. Did you verify that all the packages are available in your environment?

Thanks

Yes, the packages required by the script are satisfied and the script has been sourced by root once already on this system.
When a non-root user tries to source the script on the same host, they are asked for sudo permissions right away.

When running without root/sudo permissions:

Dear customer

You might be seeing those errors because the script tries to install the required packages which require root permissions by default. You need to manually disable those install steps that are trying to install the packages required. However please make sure you have the exact packages with the exact versions the script tries to install or else might see other issues with further development steps

Please feel free to let us know if you have any follow up questions

Thanks

It looks like the main issue is actually in the sdk_setup.sh that is called by the vitis_setup.sh file.

Lines 33-40 are setting explicit root permissions on a file in /tmp, is this required to be owned and created by the root user? Does the sdk_root_env.exp file need to be writable by any user that is going to be running this vitis_setup.sh?

 33 sudo rm -f /tmp/sdk_root_env.exp
 34 typeset -f allow_non_root > /tmp/sdk_root_env.exp
 35 echo "export AWS_FPGA_SDK_GROUP=${AWS_FPGA_SDK_GROUP}" >> /tmp/sdk_root_env.exp
 36 echo "export AWS_FPGA_SDK_OTHERS=${AWS_FPGA_SDK_OTHERS}" >> /tmp/sdk_root_env.exp
 37 echo "export SDK_NON_ROOT_USER=${SDK_NON_ROOT_USER}" >> /tmp/sdk_root_env.exp
 38 echo "export AWS_FPGA_SDK_OVERRIDE_GROUP=${AWS_FPGA_SDK_OVERRIDE_GROUP}" >> /tmp/sdk_root_env.exp
 39 sudo chown root:root /tmp/sdk_root_env.exp
 40 sudo chmod 700 /tmp/sdk_root_env.exp
