I needed the package mentioned in the title, but it fails to install due to some problems with the dependency configuration in the original package.
Here’s the resulting package.
Steps to build:
Create some directory where you want to build this. Change to that directory. Then…
sudo apt-get build-dep python-qwt5-qt4
(installs dependencies for building)
sudo apt-get source python-qwt5-qt4
This should download the package source. Download the patch from the comment I linked to above, then change into the directory and patch the files. You may have to change the directory ownership so that your user can write to it (sudo chown -R yourusername .)
patch -p0 < ~/Inbox/pyqwt-final.diff
(of course your patch may be located in a different location)
Per the GPLv2, here's the patched source I used to build the .deb file (note -- I think you can just download this instead of patching it yourself).
Once it's patched, rebuild it with:
sudo dpkg-buildpackage -rfakeroot -uc -b
Go get a cup of coffee or whatever, it's a fairly involved build. When it's done, in the directory above you should find your .deb packages. A simple:
sudo dpkg -i python-qwt5-qt4_5.1.0.dfsg-2_amd64.deb
(replace the filename with whatever yours is, of course)
will install it for you. Hope this is helpful for someone, as I wasted a few hours trying to install this all from source and so on.
