~/digikam-sc/core/libs/dmetadata/dmetadata.cpp: In static member function ‘static QString Digikam::DMetadata::valueToString(const QVariant&, Digikam::MetadataInfo::Field)’:
~/digikam-sc/core/libs/dmetadata/dmetadata.cpp:2410:1: error: control reaches end of non-void function [-Werror=return-type]

It seems that the compiler does not agree that the default case will keep the program from getting out of the switch statement without returning.  Adding the default return after the switch allows the code compile

Reproducible: Always

Steps to Reproduce:
update to head of master branch

Actual Results:  
-

Expected Results:

Stupid compiler, but I guess there is no choice to add the redundant "return QString();"

Which version do you compile ? Git/master ?

it's a gcc-4.6 warning, threathed like error,

I've adopted the same solution as Christoph Feck #c1 in sql2.0 branch, should I cherry pick it to master?
Comment 4 caulier.gilles 2011-10-23 12:11:13 UTC 
yes, sure backport it and close this entry (:=)))
Comment 5 Francesco Riosa 2011-10-23 15:49:56 UTC
