Compiling fails wiht not finding qt

[sup]

I am trying to build calibre from source (impatient to try a fix for my problem: https://www.mobileread.com/forums/sho....php?p=3111149) on Ubuntu 15.04 but fail:

I think I have all qt5 dev files installed:

dpkg --get-selections | grep qt |grep  dev

qtbase5-dev:amd64                               install
qtbase5-dev-tools                               install
qtbase5-private-dev:amd64                       install

Any idea?

You dont need to compile from source to run calibre from source

Ah, I see. Now I admit I am confused as hell.

git clone git://github.com/kovidgoyal/calibre.git
cd calibre/src
CALIBRE_DEVELOP_FROM=`pwd`
vim calibre/__init__.py # insert print("Hello, world!") somewhere near the top
calibredb

should print "Hello, world!" Right? But it does not. I guess I am missing something very obvious:-(.

[kovidgoyal]

export CALIBRE_DEVELOP_FROM=`pwd`

Ah, thanks. Stupid me.
