Subject: libicu-dev is not Multi-Arch compatible

Date: Thu, 15 Sep 2016 12:06:14 +0200

Package: libicu-dev
Version: 57.1-4
Severity: normal

Dear Maintainer,

libicu-dev is not multi-arch aware, causing the i386 version to conflict
with the amd64 one which makes it impossible to install both. As a
result the /usr/lib/i386-linux-gnu/libicu*.so symbolic links are missing
so that developping 32 bit applications using this library is
impossible on a 64 bit system.

In turn this impacts Wine development as it needs to support both 32 and
64 bit Windows applications and needs libxml2-dev for that. libxml2-dev
itself is multi-arch same but it depends on libicu-dev and thus it's
impossible to install both versions of libxml2-dev at the same time.

Hi,

I had a quick look into it and this is blocked by /usr/bin/icu-config being
arch specific. Not sure if there is an easy solution.

Package: libicu-dev
Version: 57.1-5
Followup-For: Bug #837898


This bug breaks Wine development.

A lot of Windows applications are 32 bit applications which can only be
run in a 32 bit process, so from a 32 bit Wine binary loading 32 bit
Linux libraries. But a growing number of applications are 64 bit so that
Wine developers really need to be able to build both the 32 and 64 bit
versions of Wine on their machine.

One of the packages that Wine depends on and which is needed by many
Windows applications is libxml2-dev which depends on libicu-dev. So the
lack of multiarch support translates into the lack support fo important
Windows features like .Net applications, MSI (half the applications
installers), gameux, mshtml and urlmon.

So because libicu-dev no longer supports multiarch, libxml2-dev's
multiarch support is all for nothing and Wine development is hampered.

Since this is a regression from version 52.1-8+deb8u4 and 55.1-7
I looked into them and from my perspective they had the obvious and
correct fix: icu-config belongs to icu-devtools, a Multi-Arch: foreign
package.

I also found bug 776821 which claims that was causing other problems:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=776821

That bug said the right fix was to get rid of icu-config. However I am
not seeing any movement towards that so until that ball gets rolling
it's just not a solution at all.

So that leaves another proposed solution:
* moving most of libicu-dev to libicu-dev-multiarch which would be
  m-a:same
* make libicu-dev m-a:no and keep icu-config in it
* make libxml2-dev depend on libicu-dev-multiarch and add a build-dep
  on libicu-dev.
  
This would make libxml2-dev usable again for multiarch development
without impacting other packages (unless they too want better multiarch
support).

Subject: Please remove icu-config as it is no longer used by libicu-dev's reverse dependencies

Date: Thu, 10 Aug 2017 08:52:40 +0000

Package: libicu-dev
Version: 57.1-6
Followup-For: Bug #837898

Dear Maintainer,

I have checked all 19 reverse dependencies of libicu-dev. Only one 
package (fis-gtm-6.3-000a) uses icu-config, and even then, it
is only used if detected during configure. If not present, the
configure script works around this, so it could be easily adjusted
to use pkgconfig instead.

Taking this into consideration, it is now safe (and reasonable) 
to remove icu-config from the package and restore
multi-arch support.

This, in turn, allows libxml2-dev to be installed for multiple
architectures simultaneously and greatly benefits the 
Wine project.

As things stand, not having multi-arch support in libicu-dev
is a serious blocker for many projects.

So let's move forward and resolve this bug.  :-)

 Thanks for taking care, much appreciated.

 Upstream released 59.1 some months back and while the previous
upstream release (58.2) is packaged for experimental already, the new
one and its transition is still pending. I'll take care of it when
arriving home after the short vacation of DebConf'17.

 I've checked more packages as ICU 59.1 is ready to be uploaded now.
It seems several needs patching, some due to the missing icu-config
file.

 Indeed, to date all package can be updated not to use that file.

 Are you involved with these projects, I mean can you do deep testing
with new ICU if I make it available to you?

Right, ICU 59.1 would also have other changes from the version 
currently in unstable and testing.

That's good news. And fortunately, using pkg-config is quite simple.

I am involved with the Wine project, which uses libxml2 in our msxml3
handler. We do have tests, but they are probably not rigorous enough.

If you think it's necessary, you could approach the Debian XML/SGML Group 
for additional testing. That said, I was able to rebuild the libxml2 Debian 
package from source without any errors.

I also compiled the upstream libxml2 package, which has extensive tests 
(run these by calling 'make test' after './autogen.sh --without-python --with-icu').
Again, there were no errors.

So, my recommendation is to upload the package to unstable. :-)

Do you have any plans yet to start the transition to move this to
unstable?

If you're waiting on a rebuild of the packages that depend on this one
to see if any breaks, perhaps I can give it a try in a week or so.
