Calibre 5.71 - CLI - Message error when adding books/exporting data

Windows 10 - Calibre 5.71

When I add books or export data through a batch file, I get this error message (since calibre v5.xx) :

Code:

Could not contact the running instance of calibre (<-- free translation from french...)

Failed to connect to Listener at: \\.\pipe\CalibreGUI-adminx with error: QLocalSocket::connectToServer: Invalid name

QWidget: Must construct a QApplication before a QWidget

Despite this message, everything works as expected: books are added, exports are done correctly, so I just wanted to point out this little problem.

What is your batch file doing exactly?

Here it is (only relevant parts, the whole script is checking various things before, not related to calibre)

Add books :

Code:



calibre-debug -s

calibredb --library-path %biblio% add -d %dest% 1>nul 2>&1

Export all data :

Code:



calibre-debug --export-all-calibre-data %destination% %calibre% > nul

Edit : I've just found out, if I remove the redirections ( 1>nul 2>&1), this message doesn't appear anymore.
Strange, I've been using this script for years.

Well the first couple of lines of the eror message will happen if there was no running calibre to shutdown. The last lineis a bug and will be fixed in the next release. Note that if you want to avoid the first two lines use

calibre -s

instead of

calibre-debug -s
