a bug has been introduced with this commit:
http://quickgit.kde.org/?p=kdelibs.git&a=commitdiff&h=b9201497f65bc7097c7c2a6b83eaa68891463b32

The KCalendarSystem::weeksInYear(QDate const&,
KLocale::WeekNumberSystem) const is declared in kdecore/date/kcalendarsystem.h,
but there is no implementation in kdecore/date/kcalendarsystem.cpp

This is causing smokekde build to fail with:
Linking CXX shared library ../lib/libsmokekdecore.so
CMakeFiles/smokekdecore.dir/x_2.o: In function
`__smokekdecore::xcall_KCalendarSystem(short, void*, Smoke::StackItem*)':
x_2.cpp:(.text+0x251f): undefined reference to
`KCalendarSystem::weeksInYear(QDate const&, KLocale::WeekNumberSystem) const'
collect2: ld returned 1 exit status
make[2]: *** [lib/libsmokekdecore.so.3.0.0] Error 1
make[1]: *** [kdecore/CMakeFiles/smokekdecore.dir/all] Error 2
make: *** [all] Error 2

Reproducible: Didn't try

Steps to Reproduce:
install kdelibs 4.6.80/git
try to build smokekde 4.6.80/git

Actual Results:  
build fails
