I don't know, but Ubuntu has a bug for replacing lcms v1.

There is no reason, that Wine is the last app, which depends on lcms v1.

For most apps it will be a matter of adding a configure check for lcms2
and then recompiling. This is not the case for Wine as you have pointed out.

At this point there's probably still a substantial number of users on
distributions that don't include lcms2, and trying to support both doesn't
make the source any prettier.

So it doesn't seem unreasonable to wait a little longer.

On the Ubuntu side, all supported versions have liblcms2.

As far as source prettiness goes, it will be much easier to manage the
transition as a distribution if we can know that Wine is ready rather
than waiting on others to act (who in turn may be doing the same thing).

Thanks,

- cmsCreateLabProfile was renamed to cmsCreateLab2Profile 
  cmsvirt.c (1.19: 570) / (2.4: 458 and 497)

- cmsSetLogErrorHandler can be used as replacement for cmsSetErrorHandler

The changes to support both versions are resonable small.
Missing support for lcms2 in the next stable Wine release is bad.

gnome-settings-daemon / gnome-color-manager / openjdk and some other
depend at least since Ubuntu 1110 on lcms2.
(lcms2: 8 Packages, lcms1: 47 Packages)

In current distributions, the package list include libreoffice, gtk3,
libraw, libkdcraw, poppler, ImageMagik, inkscape, scribus, calligra,
cups-filters ... more than 50 packages.
(That's for Ubuntu 1304 and Suse 1203)

I see no reason to wait any longer.

There's more. lcms1 carried the icc34.h header that defines the ICC format.
It's included via lcms.h and we depend on it for functionality that the lcms1
API doesn't provide.

I have some hope that the lcms2 API will be sufficient for this functionality,
otherwise we may have to carry this header ourselves.
