[Ctk-developers] Fwd: [mitk-users] MITK with Latest CTK - problem with DCMTK

[Clarkson, Matt]

Hi there CTK-ers,

please can anyone help me out with a CTK / DCMTK problem?  It looks to me like recent changes to CTK stop CTK working with the official DCMTK snapshots which are used in MITK.
Is that right?

If anyone can shed light on the way forward, Im happy to try and help here.

Thanks

Matt

Hi Matt,

MITK's super build is using dcmtk-3.6.1_20120222, but there is a newer snapshot here [1] and from a quick look through the Changes we could upgrade if it compiles with MITK. If you like to try it you could replace the URL in CMakeExternals/DCMTK.cmake (and remove or adapt the URL_MD5 line).

I'm not sure though that the CTK change you mention will work with that snapshot. CTK by default uses a forked version of DCMTK and there has been some activity lately. IIRC we agreed that CTK _should_ always build with the official DCMTK snapshots as well, but I'm afraid that doesn't get tested regularly. So if that is broken we should contact JC if the changes can be made in a compatible way.

If you could confirm that MITK builds with the newer snapshot we could upgrade this on our side. Unfortunately I can't test it myself at the moment.

Upgrading the CTK version can be more tricky, Sascha could maybe comment on that. If you are just interested in the slider tick change, we could also use a special version, did that before.

Best,

Marco

Hi there,

Following the merging of CTK issue #313 to CTK master (CTK commit 099a88bb24), I then tried to update my MITK to compile with this version of CTK, so I could pick up Miklos's new slider tick interval.
However, in the CTK master branch, commit 52d9539f5e, which is 3 before the latest, causes CTK to not build using the DCMTK version that MITK is using.

So, it looks to me like MITK will need to consider upgrading DCMTK before they can move to the latest CTK, which is the reason I post here, instead of the CTK mailing list.

However, I don't really understand what the reason for the CTK change is, or why CTK has a different fork of DCMTK, or what exactly is the version of DCMTK that MITK is using - dcmtk-3.6.1_20120222.tar.gz, so Im a bit stuck.

Can anyone in MITK-land shed a light on a way forward?

Thanks

Matt
