[support] Fail to build after the merging of TDX verifier about kbs HOT 10 CLOSED

thanks @jialez0 , I will try to find a host with a Ubuntu22.04 and check it again, pls let this issue open for couple of days.

from kbs.

seems like the server doesn't have the feature of tdx supported, anyway for us to disable the feature? I don't think tdx should be a must-have for only building the AS and kbs.

@chendave Maybe you can try to update libclang version and try to make again?

from kbs.

@chendave In fact, the platform for compiling and running KBS and AS does not need to support any TEE feature, but only needs to install relevant dependencies. With regard to the problems caused by the step of install dependencies, we are planning to provide Dockerfile to make it easier for users to deploy KBS and AS.

@jialez0 thanks for the quick response!

but which version is the minimal required, I tried both 1:6.0-41~exp4 and 1:6.0-41~exp5~ubuntu1 on two different x86 server, hit the same issue,

# dpkg -l libclang-dev

@chendave Hi, I have take a quick test:

First, I start a brand-new Ubuntu22.04 container:

docker run -it --name=kbs-complie-test ubuntu:22.04

Then I run the following commands in the container to build KBS and AS:

cd /root
sudo apt-get update
sudo apt-get install -y libssl-dev pkg-config curl git protobuf-compiler libprotobuf-dev gnupg make cmake clang libclang-dev golang
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source "$HOME/.cargo/env"
sudo curl -L https://download.01.org/intel-sgx/sgx_repo/ubuntu/intel-sgx-deb.key | sudo apt-key add -
sudo echo 'deb [arch=amd64] https://download.01.org/intel-sgx/sgx_repo/ubuntu focal main' | sudo tee /etc/apt/sources.list.d/intel-sgx.list
sudo apt-get update
sudo apt-get install -y libtdx-attest-dev libsgx-dcap-quote-verify-dev

cd /root
git clone https://github.com/confidential-containers/kbs
cd kbs
make

cd /root
git clone https://github.com/confidential-containers/attestation-service
cd attestation-service
make

And I haven't encountered the problems you have encountered.

from kbs.

@chendave Here is my clang version:

apt-cache policy libclang-dev
libclang-dev:
  Installed: 1:14.0-55~exp2
  Candidate: 1:14.0-55~exp2
  Version table:
 *** 1:14.0-55~exp2 500
        500 http://archive.ubuntu.com/ubuntu jammy/universe amd64 Packages
        100 /var/lib/dpkg/status

from kbs.

@chendave I think the reason for this issue may be that the OS version (ubuntu18.04) you are using is old, resulting in the incompatibility between the installed libclang-dev version and the dependency of AS.

@chendave This issue may can help you: kata-containers/kata-containers#6365 (comment)

from kbs.

@jialez0 thanks!

the issue has been fixed, something I have done on my desktop,

• upgrade system from 18.04 to 20.04
• reinstall all the packages by:

sudo apt-get update
sudo apt-get install -y libssl-dev pkg-config curl git protobuf-compiler libprotobuf-dev gnupg make cmake clang libclang-dev golang

• then make kbs again.
