caladan: cannot find macro `llvm_asm`

Hi,

Thank you for your clear instructions in compiling Caladan! I’m trying to compile and run Caladan on the XL170 machines in CloudLab (running Ubuntu 18.04.6 LTS, kernel 4.15.0-191-generic) . All instructions worked out fine until the very last step of building the synthetic client-server application.

Specifically, cargo build --release fails to compile Shenango. Any idea on how to resolve this? Below is the output

I’d greatly appreciate your help!

Best regards, Hamed
