Qt - getting "warning: format not a string literal and no format arguments"

Question

Keep getting warnings on lines like these

qDebug("An error occured while trying to create folder " + workdir.toAscii());

workdir being QString()

warning: format not a string literal and no format arguments

Answer 1

That should probably be:

qDebug("An error occured while trying to create folder %s", workdir.constData());

since qDebug takes const char* as first argument.

Answer 2

When debbuging with qDebug, I find the following syntax much easier :

qDebug() << "An error occured while trying to create folder" << workdir;

To do this, you'll need to include the <QtDebug> header.
