Failed to build extension pictureflow

[xiatian]

Hi,
I'm trying to build calibre for several times but I got an error:

Error while executing: sip -w -c /root/calibre/build/pyqt/pictureflow -b /root/calibre/build/pyqt/pictureflow/pictureflow.sip.sbf -I/usr/local/lib/python3.5/dist-packages -x VendorID -t WS_X11 -t Qt_5_7_1 -x Py_v3 /root/calibre/src/calibre/gui2/pictureflow/pictureflow.sip

I have no idea how to handle this error. The full output is as the following:

Already up-to-date.

I really hope someone can help me! Thank you guys!

Looks like you're trying to mix and match Python 3.x and Python 2.x to me. calibre uses the latter.

I installed sip with python3. Is this the problem?

[xiatian]

Nevermind, I managed to use CALIBRE_DEVELOP_FROM variable to work around problems of building from source. Thank you, anyway!

[DiapDealer]

That's the easiest way by far.

Get the extension from https://netgears.support/netgear-genie-support and make some changes in the backend with the instructions in the help section.
