Package name: pikepdf Issue type: Missing package Link to PyPI page: https://pypi.org/project/pikepdf Link to piwheels page: https://www.piwheels.org/project/pikepdf Version: > 0.9.1 Python version: 3.5+ I am the maintainer: No More information:

pikepdf is a nice library to manipulate PDF's and is used by OCRmyPDF (which does what the name says). It would be nice if this library is available.

Detailed instructions about the installation can be found here: https://pikepdf.readthedocs.io/en/latest/installation.html

I'm also facing problems building pikepdf on raspberry pi. Is there any change to add it to piwheels.org?

Thanks ! :)

Installing pikepdf has the following requirements:

• a C++14 compliant compiler - GCC (5 and up), clang (3.3 and up), MSVC (2015 or newer)
• pybind11
• libqpdf 10.0.3 or higher from the QPDF project.

On Raspbian the following Versions of libqpdf are available:

• stretch : 6.0.0-2
• stretch-backports: 8.0.2-2
• buster: 8.4.0-2
• bullseye: 10.0.4-1

So, if I'm not wrong, the part which makes it difficult is that Raspbian only provides very old versions of libqpdf. Correct me if I'm wrong...

Yes that seems to be the case, in which case it's probably not buildable until (perhaps) Bullseye is out.

If someone likes to use pikepdf, these steps can be used to install the package (tested on Raspbian Buster):

sudo apt install libjpeg-dev
curl -OL https://github.com/qpdf/qpdf/releases/download/release-qpdf-10.3.2/qpdf-10.3.2.tar.gz
tar -xf qpdf-10.3.2.tar.gz
cd ./qpdf-10.3.2
./configure; make; sudo make install
sudo ldconfig
pip3 install --user pikepdf  # --> This should work now!

This installs a new release of qpdf which is compatible with pikepdf. Note that this might break if another version of qpdf is already installed! Use at your own risk!
