[Digikam-users] Re: svn build fails: testlensiface has undefined reference to lkdecore

[Gilles Caulier]

Done with commit #1180475. But it's abnormal, because testlensfuniface
is already linked with KExiv2, through digikamcore internal library.
No need to duplicate it. Look there :

http://lxr.kde.org/source/extragear/graphics/digikam/digikam/CMakeLists.txt#186

Sound like your CMake or devel env has a problem. Both Linux and
Windows version compile fine there...
