@ratnadeepb If you're building without docker or our vm (via vagrant), take a gander here: https://github.com/capsule-rs/sandbox#without-docker. You'll need to install dpdk, etc... Let me know once you follow the directions in there.

[ratnadeepb]

@zeeshanlakhani actually I have been working on something similar. I have been using a slightly modified version of your ffi crate and core/dpdk module. I can build things fine. But when I try to build this repo from source it throws me this error.

Pre-requisites wise, I have the following libs installed - build-essential linux-headers-$(uname -r) git libnuma-dev linux-modules-extra-$(uname -r) libclang-dev clang llvm-dev libpcap-dev dpdk-igb-uio-dkms ninja-build. I am building DPDK with meson 0.56 and ninja 1.8.2. The igb_uio driver is from dpdk.org/dpdk-kmods.

This is what confuses me: The build script I use is mostly a derivative of the one you have. And for the bindings.h and shim.c, I have only added to those.

Also, I am building these on cloudlab's Ubuntu18 machines (if that helps).

[ratnadeepb]

This is how my build.rs stands, in case that helps: https://github.com/ratnadeepb/vdataplane/blob/master/dpdk-sys/build.rs

[zeeshanlakhani]

@ratnadeepb I'll run up things on my Ubuntu box tonight and see. What DPDK version? Capsule uses 19.11.1 and that matters due to API breakage across DPDK versions. It seems specifically an issue in loading rte_ethdev, which we do here: https://github.com/capsule-rs/capsule/blob/master/ffi/build.rs#L47

[ratnadeepb]

This error is from DPDK 19.11.6.

[zeeshanlakhani]

@ratnadeepb ill test on that version this evening and see. I’ll be using our dpdk and setup install scripts here.

[zeeshanlakhani]

@ratnadeepb I was able to reproduce and fix. I'll push up a PR for @drunkirishcoder to test/review here and at the sandbox as well.

I repro'ed on 19.11.1, but will move us to 19.11.6 for LTS as part of this too.

We'll prob ship an ffi cargo release sometime later this week (possibly with a couple small changes, like moving to rust 1.49 too).

@zeeshanlakhani cool!
