Overview
The "gdcm-libgdcm3_0" package should be name just libgdcm3_0 (missing "-n").
I have prepared this in https://build.opensuse.org/package/show/home:DocB:Orthanc/gdcm , which leads depending packages now to fail. Is this really required to rename?
This is caused by "BuildRequires: gdcm-libgdcm3_0" in orthanc-gdcm. You already have "gdcm-devel", and that pulls in the library package itself. You should remove this.
For a transitional period, you can add "Provides: gdcm-libgdcm3_0 = %{version}", "Conflicts: gdcm-libgdcm3_0 <= 3.0.12" to libgdcm3_0.
Hi Stefan, for Orthanc-Webviewer I get a problem with this setup: unresolvable: have choice for libgdcmCommon.so.3.0()(64bit) needed by orthanc-gdcm: gdcm-libgdcm3_0 libgdcm3_0 have choice for libgdcmDSED.so.3.0()(64bit) needed by orthanc-gdcm: gdcm-libgdcm3_0 libgdcm3_0 have choice for libgdcmMSFF.so.3.0()(64bit) needed by orthanc-gdcm: gdcm-libgdcm3_0 libgdcm3_0
I have no idea where it pulls the gdcm-libgdcm3_0 from, as this has been removed - do you see this by chance? -> packages in my home-project above
PS: Can be fixed in prjconf....anyhow, would like to answer the question
Likely missing "Conflicts: ..."
Your home project also gets all packages from its parent project, i.e. "graphics".
Missing "Conflicts:"/"Obsoletes:", see https://en.opensuse.org/openSUSE:Package_dependencies#Renaming_a_package
