Description Steve Grubb 2019-10-01 19:27:42 UTC
When compiling a program written for rust on ppc64le, I get the following error:

Description of problem:

error: Could not compile `suricata`.

This compiles fine on other arches. I'm wondering if something is missing on the ppc64le that other arches have. This is against the rawhide version.

How reproducible:
Every time

Steps to Reproduce:
1. Build rawhide version of suricata on ppc64le system

Comment 1 Josh Stone 2019-10-01 19:47:18 UTC
Those symbols are supposed to be provided by libjansson, right? I don't see -ljansson on the link line.

But this is only in "cargo test" -- are the Json functions not involved in testing? Perhaps other arches are doing a better job of pruning this?

Comment 2 Josh Stone 2019-10-01 22:03:53 UTC
I reproduced this with rust-1.37.0-1.fc30.ppc64le + llvm-libs-8.0.0-6.fc30.ppc64le, so the problem is not rawhide's newer toolchain.

It works if I add a link attribute in src/json.rs:

/// Expose the jansson functions we need.
#[link(name = "jansson")]
extern {
    fn json_object() -> *mut JsonT;
    ...
}

Comment 3 Steve Grubb 2019-10-03 20:39:05 UTC
I did a new build that let's all arches finish instead of fail-fast:
https://koji.fedoraproject.org/koji/taskinfo?taskID=38039091

ppc64le is the only one failing. I wonder if something is different on that platform?

Comment 4 Cameron Kaiser 2019-10-17 22:30:24 UTC
Could this be related to bug 1756838?

Comment 5 Ben Cotton 2020-02-11 17:51:15 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 32 development cycle.
Changing version to 32.

Comment 6 Dan Horák 2020-05-05 09:13:11 UTC
The problem is still in Rawhide.

Josh, what component needs to be fixed? Is it rust, libjansson or something else? Where your workaround should go in?

That was in suricata's src/json.rs, and in fact I think that's correct to require, not just a workaround.
(But I still don't really know why only ppc64le is affected.)

Comment 8 Ben Cotton 2020-08-11 15:20:32 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 33 development cycle.
Changing version to 33.
