<Missing title> related to ARM breakage #41

MagaTailor · 2016-01-05T02:30:05Z

Hi,

I guess you haven't caught up with this issue yet :)
Here's a first, coming from an ARM Linux machine using 1.7 nightly:

BTW:
Is there a way to disable building wayland dependencies on X? It's really slow on arm...

The text was updated successfully, but these errors were encountered:

elinorbgr · 2016-01-05T10:11:47Z

You are using wayland-client-0.2.1, which is a really outdated version, current version is 0.5.6.

Given your question, I guess you are depending on wayland-client through glutin? If so it's a question you should ask there.

MagaTailor · 2016-01-05T11:39:55Z

Correct, yours is the first crate to not have this issue in the latest version without targeted fixing. Well done!

Not that it'll help much without updating all dependencies.

MagaTailor · 2016-01-05T14:37:38Z

It seems I let you off the hook too easily :)

Using 0.5.6 from within an actual project (or rather on rust 1.5) exhibits the issue after all:

Using stable rust 1.5 this time.

elinorbgr · 2016-01-05T14:46:13Z

Hmm, this is troubling, I'm using libc 0.2 everywhere, so this error should not show up...

Can you tell me which versions of wayland-client, wayland-sys, wayland-scanner and dlib is used in your Cargo.lock ?

elinorbgr · 2016-01-05T14:47:32Z

Ah yeah, libc 0.2 is not compatible with Rust 1.5 and prior (from the rust issue)...

So, I guess my lib is only usable on ARM using rust 1.6 or newer

I can't really fix that though, the incompatibility comes from rust itself

MagaTailor · 2016-01-05T14:50:26Z

If you don't require beta/nightly to build there's no problem to fix it. It's normally done via casts like as *const _ or using coercion via a variable. Have a look at other fixed crates.

elinorbgr · 2016-01-05T14:53:52Z

Hmm, ok, I'll see what I can do about that.

elinorbgr · 2016-01-06T16:17:25Z

Hopefully #42 should fix this issue.

MagaTailor · 2016-01-06T17:56:27Z

With typos like ow? ;) Owww!

Have a look at some more issues building with 1.5:

I was fixing that, but messed things up a little.
I should stop fixing things while sick, I guess.
I'll publish 0.5.8 with fixes asap.

MagaTailor · 2016-01-06T18:34:28Z

Take your time, no need to rush - wayland can wait a little bit longer ;)

elinorbgr · 2016-01-06T18:42:07Z

Okay.

0.5.8 is published, and should be corrected (at least it builds correctly on x86).

Can you tell me if it solves the breakage on ARM ?

MagaTailor · 2016-01-06T18:52:20Z

Yup! Thanks.

elinorbgr · 2016-01-06T18:53:40Z

Okay, perfect. 😄
