Unable to compile Calibre on a Raspberry 4 (RaspberryOS)

[knolle75]

I am trying to build Calibre from source since after the distri upgrade to the latest v12 aka Bookworm (what a surprise ) no binary package is advised by the standard repositories.

This my current notebook where I worked around some road blocks:

Build podofo from source
https://github.com/podofo/podofo

Install dependencies
sudo apt-get install -y libfontconfig1-dev libfreetype-dev libxml2-dev libssl-dev libjpeg-dev libpng-dev libtiff-dev libidn11-dev cmake

Clone the repository
git clone https://github.com/podofo/podofo.git

Run the build procedure
cd podofo
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Debug ..
cmake --build . --config Debug

Install locally
sudo make install

Build calibre from source
https://github.com/kovidgoyal/calibre

Install dependencies
sudo apt install -y libfreetype6 libhunspell-dev qmake6 libuchardet-dev python3-dev libhyphen-dev libicu-dev libsqlite3-dev libstemmer-dev libusb-1.0-0-dev libmtp-dev pyqt6-dev sip-dev python3-pyqt6 python3-pyqt6.sip pkgconf python-is-python3 python3 g++ git

Clone the repository
git clone https://github.com/kovidgoyal/bypy.git
git clone https://github.com/kovidgoyal/calibre.git

Run the build procedure
cd calibre/
export PODOFO_INC_DIR=/usr/local/include/podofo
python3 setup.py install

However, I am stuck at this point:
-c: /home/nico/calibre/build/pyqt/rcc_backend/rcc.sip: line 19: column 9: 'QtCore/QtCoremod.sip' could not be found

calibre comes with prebuilt arm and intel 64 bit binaries. You dont need to build from source.

Thanks for the fast response, however please consider the the OS being 32bit, as the original Raspberry OS (based on Debian) still is. This is running on a ARMv7, aka armv7l.

[kovidgoyal]

I am pretyt sure the RPI4 supports 64 bit OSes. As for your error it means the PyQt6 sip files are not installed.

[knolle75]

I dont decline that, only saying the current Raspberry OS is a 32bit, which is the reason I am looking to the from-source installation.

For the presence of the missed file, I would expect the existing files will detected some how.

Considering that the currently, QT does not supply 32-bit binaries for QT6, compiling calibre versions 6/7 is going to require you to build your own 32-bit version or find one of the few distros that include a pre-built 32-bit QT (I vaguely remember seeing one for Debian but not certain what the CPU support was).

It might be easier to install the 64-bit version of Raspberry Pi OS which has been around since early 2020.

It may be true that you have installed the 32-bit version, however here's the 64-bit of Raspberry OS:

Thank you @rantanplan and @DNSB. I hear what your saying and it seems, there is a task pending, to met some prerequisites.

Will add it to my backlog for now.

mentions something about a missing file 'QtCore/QtCoremod.sip'. Double-check if that file is in the right place or if it's missing. Sometimes it's just a small mix-up causing this. Maybe try re-downloading the source files or checking if there's a typo in the file name. Hope this helps!

The thing is, there is Python import statement but I am not clear which base directory it expects. Python or Qt are not my favorite programming languages.
