method not found in ScmpFilterContext

[Wangyiwei-So]

I try to compile runwasi in ubuntu:
I tried ubuntu:23.10 container:

uname -a
Linux 004aed56de46 6.7.0-arch3-1 #1 SMP PREEMPT_DYNAMIC Sat, 13 Jan 2024 14:37:14 +0000 x86_64 x86_64 x86_64 GNU/Linux

and a ubuntu:20 machine

uname -a
Linux test 5.4.0-65-generic #73-Ubuntu SMP Mon Jan 18 17:25:17 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

I installed dependencies

apt-get install -y build-essential
apt-get install -y protobuf-compiler
apt-get install -y libseccomp-dev

and got this message

make build FEATURES=wasmedge
error[E0599]: no method named `get_notify_fd` found for struct `ScmpFilterContext` in the current scope

May I ask you to make sure that you installed libseccomp-dev 2.5+.

May I ask you to make sure that you installed libseccomp-dev 2.5+.

thank you for your reply!

yes, 2.5.4 has been installed

apt-get install -y libseccomp-dev

Hi @Wangyiwei-So ,

Could you do cargo clean -p libseccomp -p libseccomp-sys and then try building again?

If you've tried building without installing libseccomp-dev, then the libseccomp and libseccomp-sys dependencies are build with partial support. If you don't run cargo clean ..., those dependencies will not be rebuilt with full support, even when you run make build ... just build ... again.

[Wangyiwei-So]

Thank you! @jprendes
I tried the method you mentioned, but still...

$ cargo clean -p libseccomp -p libseccomp-sys
$ make build FEATURES=wasmedge
/bin/sh: 1: sudo: not found
cargo build --target=x86_64-unknown-linux-gnu --target-dir=./target/ -p containerd-shim-wasm --no-default-features --features generate_bindings

@Wangyiwei-So Where did you get the FEATURES=wasmedge I don't believe we use the FEATURES env anywhere. Are you trying to build just wasmedge? If so can you try make build-wasmedge

For deps, did you run scripts/setup-linux.sh? It has a few other deps than just the three listed above

[utam0k]

Just be sure to use the latest runwasi code.

Compiling libcontainer v0.3.0

[Wangyiwei-So]

@jsturtevant @utam0k thank you both very much, i tried two methods, but report same error. do you have builder image?

[utam0k]

What's a builder image? Dockerfile?

[Wangyiwei-So]

@utam0k yes. sorry i use google translator

[jprendes]

@Wangyiwei-So , you could run the makefile with CARGO=cross, that will run the build inside a Dockerfile.

make CARGO=cross build-wasmedge

You will need to install cross-rs with

cargo install cross --git https://github.com/cross-rs/cross

Related to this issue, youki/libcontainer starts to implement their own seccomp crate which may resolve this issue.
