Bug Description

When I run a software which it write with and build in 32bit system in a 64bit system.
It can't work a global meun and the HUD.

I test this in Ubuntu 12.04 64bit,and the version of unity is 5.12.0.
And we can reproduce it run the little program (attachment) in 64bit sysytem which I write it with Qt and build in 32 bit system.
(You may should install ia32-libs to support 32bit software in 64bit system)

And this is the output information:

Unable to load library icui18n "Cannot load library icui18n: (libicui18n.so.48: wrong ELF class: ELFCLASS64)"

Which version of Qt did you build it with? Seems like it doesn't honour multiarch.

That makes sense. It needs to be rebuilt on a 64 bit system before it could work.

Please check if it is fixed when you recompile the application for 64-bit. Seems like your system doesn't handle multiarch well, and as such, you need different binaries for 32-bit and 64-bit (which is the recommended procedure)

If multiarch libs were handled well, then this bug won't have popped up in your case. Sadly, multiarch hasn't been sorted out perfectly for every package yet, and appmenu isn't multiarch-optimized yet.

Yes, I have updated my system to the newest and this bug still exist.
I used the Qt library in Ubuntu's software source.

And what information should I provide more?

As always, recompiling the application for both architectures is the recommended procedure for app developers. But I'll triage this, since appmenu-qt should handle multiarch properly, just like other libraries.

Yes, recompiling the application for both architectures is the recommended procedure for app developers.
But, there are so many close source software didn't compile for 64bit. And as users, they can't do anything when they run those software in Unity 64bit.
So I think it is necessary to let appmenu-qt support multiarch.

appmenu-gtk now has multiarch support (https://bugs.launchpad.net/ubuntu/+source/appmenu-gtk/+bug/932860).
Will this be updated too?

The attachment "Multiarch support for appmenu-qt" seems to be a debdiff. The ubuntu-sponsors team has been subscribed to the bug report so that they can review and hopefully sponsor the debdiff. If the attachment isn't a patch, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are member of the ~ubuntu-sponsors, unsubscribe the team.
