#41709: Mac OS X- loading two sets of Qt binaries into the same process
-------------------------------------+--------------------------------
 Reporter:  gtmdhl@…                 |      Owner:  macports-tickets@…
     Type:  defect                   |     Status:  new
 Priority:  Normal                   |  Milestone:
Component:  ports                    |    Version:  2.2.1
 Keywords:  two sets of Qt binaries  |       Port:  digikam
-------------------------------------+--------------------------------
 I have followed the routine of installing Digikam on Mac OS 10.9 as
 suggested by Gilles Caulie. I continue to experience an unstable program
 which crashes easily upon almost any simple menue command. Perhaps the
 followng error message is the cause.

 "On Mac OS X, you might be loading two sets of Qt binaries into the same
 process. Check that all plugins are compiled against the right Qt
 binaries. Export DYLD_PRINT_LIBRARIES=1 and check that only one set of
 binaries are being loaded.
 QObject::moveToThread: Current thread (0x7fdce9c028e0) is not the object's
 thread (0x7fdce9de92a0).
 Cannot move to target thread (0x7fdce9c028e0)"

 I have attempted to research the issue on Macports through the ticket
 system. I found Ticket # 19217 which addresses some of this issue but I do
 not see any recommendations as to a process to resolve the issue.
 Regarding the reference of DYLD , "Export DYLD_PRINT_LIBRARIES=1 and check
 that only one set of binaries are being loaded". My search of the MacPorts
 Ticket issues found little of the DYLD issue and did not suggest how to
 use the libraries.

 Any assistance or suggestions as to what I might do to correct these
 issues will be appreciated.
