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

[sean darcy]

Thanks. That fix worked. But now libexiv2:

/usr/bin/ld: CMakeFiles/testlensfuniface.dir/testlensfuniface.o: 
undefined reference to symbol 'KExiv2Iface::KExiv2Data::~KExiv2Data()'
/usr/bin/ld: note: 'KExiv2Iface::KExiv2Data::~KExiv2Data()' is defined 
in DSO /usr/lib64/libkexiv2.so.9 so try adding it to the linker command line
/usr/lib64/libkexiv2.so.9: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
make[2]: *** [libs/dimg/filters/lens/testlensfuniface] Error 1
make[2]: Leaving directory 
`/home/photo/rpmbuild/BUILD/digikam/x86_64-redhat-linux-gnu'
make[1]: *** 
[libs/dimg/filters/lens/CMakeFiles/testlensfuniface.dir/all] Error 2
