rpm for ppc64le platform

[bogdansavu]

I need to compile the agent for ppc64le platform. I moved the discussion from https://github.com/logdna/logdna-agent/issues/151 to this issue.

[dkhokhlov]

I tried using: [patch.crates-io] ring = { git = "https://github.com/ibm/ring.git", branch = "ppc-0.16.20" }

but I'm getting this error: error[E0599]: no method named description_ found for struct KeyRejected in the current scope --> /root/.cargo/registry/src/index.crates.io-6f17d22bba15001f/rcgen-0.9.3/src/lib.rs:1624:35 | 1624 | RcgenError::RingKeyRejected(err.description_()) | ^^^^^^^^^^^^ method not found in KeyRejected

For more information about this error, try rustc --explain E0599. error: could not compile rcgen (lib) due to previous error warning: build failed, waiting for other jobs to finish...

Any suggestion? It is something that I can fix?

@bogdansavu I noticed that ring has two branches:

- main-ppc for the somewhat-upstream version
- ppc-0.16.20 for the current latest version published to crates.io

have you tried main?

Hey @dkhokhlov

[dkhokhlov]

looks like ring build script fails. can you build ring?

sudo apt install gcc-powerpc64le-linux-gnu
git clone git@github.com:IBM/ring.git
git co main-ppc
cargo build --target powerpc64le-unknown-linux-gnu

[bogdansavu]

@dkhokhlov any other suggestion? Is something that I can do?

[bogdansavu]

@dkhokhlov I successfully compiled logdna using : ring = { git = "https://github.com/erichte-ibm/ring.git", branch = "ppc-0.16.20-rework" }

I have a question, there is any way to generate rpm packages?

[dkhokhlov]

@bogdansavu this is great! packages can be produced by:

make build-rpm
make build-deb

[bogdansavu]

this make build-rpm is failing, I don't understand why docker is needed, there is any other command that I can use for rpm build?

make build-rpm CACHE_TARGET="false" ARCH=x86_64 ./docker/dispatch.sh "/build" "/root/logdna-agent-v2:/build:Z" docker.io/logdna/build-images:rust-bullseye-1-stable-x86_64 "--env CARGO_TARGET_DIR=target/x86_64-linux-gnu --env RUST_BACKTRACE=full" "RUSTFLAGS='' BINDGEN_EXTRA_CLANG_ARGS='' cargo build --features libjournald --manifest-path bin/Cargo.toml --release --target x86_64-unknown-linux-gnu && llvm-strip ./target/x86_64-linux-gnu/x86_64-unknown-linux-gnu/release/logdna-agent" ./docker/lib.sh: line 12: docker: command not found ./docker/dispatch.sh: line 29: docker: command not found ./docker/dispatch.sh: line 33: docker: command not found ./docker/dispatch.sh: line 36: docker: command not found ./docker/dispatch.sh: line 39: docker: command not found ./docker/dispatch.sh: line 41: exit: : numeric argument required make: *** [Makefile:200: build-release] Error 2

[dkhokhlov]

we use docker container for builds. it is pre-configured with required tools. i am suggesting to install the docker.

[bogdansavu]

I installed docker but the image build is failing: ARCH=ppc64le scripts/mk.image ~/logdna-agent-v2 ~/logdna-agent-v2 DOCKER_BUILDKIT=1 docker build . -t logdna-agent-v2:0b89443-ppc64le \ \ --progress=plain \ --platform=linux/ \ --secret id=aws,src=/tmp/.aws_creds_static.WEBIEu \ --rm \ --build-arg BUILD_ENVS=" CARGO_TARGET_DIR=target/ppc64le-linux-gnu" \ --build-arg BUILD_IMAGE=docker.io/logdna/build-images:rust-bullseye-1-stable-ppc64le \ --build-arg TARGET=ppc64le-unknown-linux-gnu \ --build-arg TARGET_DIR=target/ppc64le-linux-gnu \ --build-arg TARGET_ARCH=ppc64le \ --build-arg BUILD_TIMESTAMP=2023-09-19T15:15:11Z \ --build-arg BUILD_VERSION=3.9.0-dev \ --build-arg FEATURES='--features libjournald' \ --build-arg REPO=logdna-agent-v2 \ --build-arg VCS_REF=0b89443 \ --build-arg VCS_URL=https://github.com/logdna/logdna-agent-v2 \ --build-arg SCCACHE_BUCKET= \ --build-arg SCCACHE_REGION= \ --build-arg SCCACHEENDPOINT= ERROR: "" is an invalid component of "linux/": platform specifier component must match "^[A-Za-z0-9-]+$": invalid argument make: *** [Makefile:388: build-image] Error 1

[bogdansavu]

@dkhokhlov I manually generated the rpm file, could you please have a look and let me know if you see any problem on these steps?
