'terra.cdr' opened in Inkscape build with internal cdr-input support (branch r12060) and saved as Compressed Inkscape SVG (*.svgz).

MacPorts Portfile for libcdr (git)
(port name: libcdr-devel, to be used with local portfile repository))

I only checked now which version of libcdr is provided e.g. on current Ubuntu 12.10: libcdr (0.0.8-1)
<http://packages.ubuntu.com/source/quantal/libcdr>

@Fridrich - is libcdr-0.0.8 ok, too? In the initial commit to the branch I did set min version for libcdr to 0.0.9 …

Also requires lcms2, which is not in the Windows devlibs (WIP).

Tested successfully on Windows XP, with lcms2.2.4 and libcdr-0.0.9 (libcdr-0.0.10 requires ICU, which fails to compile with mingw).

Sorry I forgot to mention it explicitly (it's a an indirect dependency already with recent poppler and ImageMagic versions on OS X).

Branch merged in r12087

Libs added to the devlibs, revision 43.
Trunk modified for win32, revision 12091.

JFTR: MacPorts now offers stable libcdr 0.0.10:
<http://www.macports.org/ports.php?by=name&substr=libcdr>
and has inkscape-devel updated to include libcdr support:
<https://trac.macports.org/changeset/102746/trunk/dports/graphics/inkscape-devel/Portfile>

Please update libcdr the latest version right now is 0.0.14. And libvisio the latest version libvisio-0.0.31.zip inkscape use right now version 0.0.23

@Viktor - please file a new request here:
<https://bugs.launchpad.net/inkscape-devlibs/+filebug>

@Viktor - just to confirm... you're talking about updating the versions of libcdr/libvisio shipped in the Windows devlibs, right? Does anything need to be done in Inkscape trunk itself to support the new versions?

@Alex - yes, it was about the Windows packages. Viktor had asked about it in the forum first:
<http://www.inkscapeforum.com/viewtopic.php?f=5&t=16409>

The request now has been filed for the Windows devlibs:
<https://bugs.launchpad.net/inkscape-devlibs/+bug/1247139>

> Does anything need to be done in Inkscape trunk itself to support the new versions?
Not to my knowledge. I use git head of libvisio and libcdr with Inkscape trunk without any problems.

@Viktor, @all - The devlibs versions are a bit old indeed. I'm going to take a look.

Alex Valavanis, why you compiled Inkscape in ppa:inkscape.dev/stable without libcdr ? I've just installed from https://launchpad.net/~inkscape.dev/+archive/ubuntu/stable and noticed, that Inkscape 0.91 doesn't open CorelDraw files until python-uniconvertor is installed.
Please fix packaging code at lp:~inkscape.dev/inkscape/debian-packaging-stable to add libcdr-dev build-deps according to bug #1104198
Ubuntu 14.04 has libcdr 0.0.15 , newer libcdr 0.1 is uploaded to Ubuntu 14.10 and 15.04.
If you need newer libcdr you can simply upload newer libcdr version to Ubuntu 14.04 or even Ubuntu 12.04 section at https://launchpad.net/~inkscape.dev/+archive/ubuntu/stable PPA

Alex Valavanis, I've noticed, that Inscape from Debian experimental already depends on libcdr-dev, see
http://anonscm.debian.org/cgit/collab-maint/inkscape.git/tree/debian?h=experimental

I think you should simply copy packaging code from Debian experimental to lp:~inkscape.dev/inkscape/debian-packaging-stable

Thanks for noticing the oversight. Build queued for stable PPA. It should fix the missing libcdr/libvisio dependency in Ubuntu versions where it's available, but this unfortunately doesn't include Precise. I'll look into the possibility of backporting the libraries to Precise tomorrow.

We can't just copy the entire Debian packaging tree, because this is a native package, not a quilt (patched) format. We also don't want to override the unit tests. I'll happily (manually) merge useful stuff from Debian though.

@Alex - this doesn't seem to work yet as expected: from the build log of 14.10:

checking for LIBWPG03... yes
checking for LIBVISIO01... no
checking for LIBVISIO00... no
checking for LIBCDR01... no
checking for LIBCDR00... no

Another user on Ubuntu 14.10 reported successful detection of libcdr and libvisio (for local trunk build) after installing the packages libicu-devtools and libicu-dev: possibly this is related - since after having those packages installed, Inkscape's configure detected the requirements for cdr and visio support as expected. The user's original config.log unfortunately was overwritten, and personally I don't have a VM with 14.10 at hand to verify what is causing the failure to detect libcdr-0.1 and libvisio-0.1 as expected.

Confirmed... it's a packaging error in Ubuntu. See bug #1359824.
