Trying to launch it gives just the generic launcher error dialog. There is nothing in ~/fcdtdebugger and the datadir ~/workspace-fcdtdebug is not created. Most probably the problem lies in http://pkgs.fedoraproject.org/cgit/eclipse-cdt.git/tree/eclipse-cdt.spec#n271 - it has to be automated as listing/symlinking bundles that way is too errorprone.
Actually a problem was that the libhover patch removed the application of patch3 which has to do with the config.ini file. The patch also needed a fix to work as the config.ini file added some needed plug-ins for this release that weren't in the patch. I have not tested the patch works. It will be in build eclipse-cdt-8.7.0-4 which has just been started.

More improvements. Some OSGI names had changed for F23 and had to be fixed in the config.ini (javax.servlet, javax.el, and lucene analyzer) See eclipse-cdt-8.7.0-5
Works with that build but this have to be automated as current state is too fragile.
I'd be interested in how you intend on automating this. Every package can have some arbitrary OSGI tag it gives. That is the problem. The config.ini file has to patch these additional names. It would be nice to just have the same config.ini file work in Fedora (i.e. packages are referred to by the same name as they are when Eclipse is downloaded).
This bug appears to have been reported against 'rawhide' during the Fedora 23 development cycle. Changing version to '23'. (As we did not run this process for some time, it could affect also pre-Fedora 23 development cycle bugs. We are very sorry. It will help us with cleanup during Fedora 23 End Of Life. Thank you.) More information and reason for this action is here: https://fedoraproject.org/wiki/BugZappers/HouseKeeping/Fedora23
Mark as closed as time not permit further investigation in automation.
