rpm for ppc64le platform

[bogdansavu]

I need to compile the agent for ppc64le platform. I moved the discussion from logdna/logdna-agent#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?

[bogdansavu]

Hey @dkhokhlov

main-ppc:

[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

[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:

[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?

git clone https://github.com/logdna/logdna-agent-v2.git
