Vector cross-compiled for ppc

[bmallya]

Can someone guide me on cross-compiling vector for ppc? Here is what I have

  sh-4.4# uname -a
  Linux a8041bffb0d9 5.10.16.3-microsoft-standard-WSL2 #1 SMP Fri Apr 2 22:23:49 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

And with this when I try to build vector providing a target, I run into an error.

Hi @bmallya !

We use cross to cross-compile Vector. We maintain docker images for the cross compilation as they need a few additional dependencies. You can see our current ones here: https://github.com/vectordotdev/vector/tree/master/scripts/cross . You should be able create a similar one for ppc named (powerpc-unknown-linux-gnu.dockerfile) and then build it using make cross-powerpc-unknown-linux-gnu

vector/Makefile

Hopefully this helps! Let us know if you have further questions.

[bmallya]

@jszwedko, Would you know which library/crate is depending on ring? I was wondering if I can build without that dependency.

Another thing that I probably wanted to run by you and get your suggestion. I made a small change in the Makefile to accept the target features and ran the following command

    make cross-build-powerpc-unknown-linux-gnu LRU="sources-exec,sources-file,sources-generator,sources-http,sources-internal_logs,sources-socket,sources-stdin,sources-syslog,sources-vector,sources-internal_metrics,sources-host_metrics,transforms-add_fields,transforms-ansi_stripper, transforms-coercer,transforms-concat,transforms-dedupe,transforms-field_filter,transforms-filter,transforms-json_parser,transforms-key_value_parser,transforms-log_to_metric,transforms-logfmt_parser,transforms-merge,transforms-metric_to_log,transforms-reduce,transforms-regex_parser,transforms-remap,transforms-remove_fields,transforms-rename_fields,transforms-route,transforms-sample,transforms-split,transforms-tokenizer,sinks-blackhole,sinks-console,sinks-file,sinks-http,sinks-socket,sinks-vector,vendor-all"

which threw up,

I tried installing the libssl package into the container through the boot-ubuntu.sh script, but that did not help either

[jszwedko]

Nice! I imagine we'd be happy to accept the Makefile enhancement if you want to open a PR.

I think you might need to install libssl-dev? That would have Vector dynamically link with it. You can also have it statically link against a vendored openssl via adding vendor-openssl to your list of features.

Unfortunately there are quite a number of dependencies on ring:

Actually! There are only a couple of deps when using your feature set:

$ cargo tree -i -p ring --no-default-features --features 'sources-exec,sources-file,sources-generator,sources-http,sources-internal_logs,sources-socket,sources-stdin,sources-syslog,sources-vector,sources-internal_metrics,sources-host_metrics,transforms-add_fields,transforms-ansi_stripper, transforms-coercer,transforms-concat,transforms-dedupe,transforms-field_filter,transforms-filter,transforms-json_parser,transforms-key_value_parser,transforms-log_to_metric,transforms-logfmt_parser,transforms-merge,transforms-metric_to_log,transforms-reduce,transforms-regex_parser,transforms-remap,transforms-remove_fields,transforms-rename_fields,transforms-route,transforms-sample,transforms-split,transforms-tokenizer,sinks-blackhole,sinks-console,sinks-file,sinks-http,sinks-socket,sinks-vector,vendor-all' --edges no-dev
ring v0.16.20
├── rustls v0.19.1
│   └── tokio-rustls v0.22.0
│       └── tonic v0.5.2
│           └── vector v0.17.2 (/Users/jesse.szwedko/workspace/vector)

└── webpki v0.21.4
    ├── rustls v0.19.1 (*)

Basically it looks like it's just the vector source/sink since they depend tonic. If I remove those two components, there are no dependencies on ring.

Thanks for the quick response @jszwedko. Really appreciate all the help you are providing me.
On the open-ssl error that I mentioned earlier, I had libssl-dev added into the boot-ubuntu.sh script

  apt-get update
    apt-get install -y \
      apt-transport-https \
      libssl-dev \
      wget
    
    # we need LLVM >= 3.9 for onig_sys/bindgen
    
    cat <<-EOF > /etc/apt/sources.list.d/llvm.list
    deb http://apt.llvm.org/xenial/ llvm-toolchain-xenial-9 main
    deb-src http://apt.llvm.org/xenial/ llvm-toolchain-xenial-9 main
    EOF
    
    wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key| apt-key add -
    
    apt-get update
    
    # needed by onig_sys
    apt-get install -y \
          libclang1-9 \
          llvm-9

In the features that I had passed to the makefile, vendor-all is also present which should also mean vendor-openssl is also in. Correct?

Unfortunately, vector as a source/sink is at the heart of the solution we are using Vector for. The intention is to have like a vendor agent running on some systems in the network. These agents would collect the logs from different sources (say http/tcp/socket) and then these are forwarded to a centralised collector (on a different system). And the way the logs are forwarded is to use vector as a sink (on the agent) and source( on the collector)

Hey! Apologies for the delayed response. Correct vendor-all will include vendor-openssl. I'm not sure why you'd be seeing those OpenSSL issues.

You could try using another source/sink pair to send data. Other users have used the splunk_hec source and sink to send logs between Vector instances. It looks like that would remove any dependency on ring.
