Calibre with Raspberry Pi 4

[jjparker]

I noticed a post regarding the installation of Calibre on the Raspberry Pi 3 which sounded like an easy thing to do. Yet, downloads seem only interested in Intel processors so how is Calibre loaded onto a Raspberry Pi 4? Keep in mind I’m a financial guy not a computer person. And does one lose functionality going this route? Would I be better off just purchasing an Apple Mac mini and accessing with my iPad via Luna?

Many thanks in advance!

There is a beta version of calibre for ARM64.

https://download.calibre-ebook.com/betas/

Follow the Manual binary install for Linux:

https://calibre-ebook.com/download_linux

sudo mkdir -p /opt/calibre && sudo rm -rf /opt/calibre/* && sudo tar xvf /path/to/downloaded/calibre-tarball.txz -C /opt/calibre && sudo /opt/calibre/calibre_postinstall]

That should work depending on you OS.

Thanks for the quick and precise response.
Much appreciated.

Thanks Bernie. Your code combined with installing Kalzium, suggested here
got me up and running with Calibre 6.1. Found here
I'm using a Raspberry Pi 400 with Raspian Desktop 64-bit OS. I did'nt even need to unistall the first failed attempt before the second successful install.

Hi indigo141,

How did you work around the glibc incompatibility? The latest 64-bit raspbian uses glibc 2.31 while the manual calibre installer requires glibc 2.34:

/opt/calibre/calibre_postinstall: /lib/aarch64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by /opt/calibre/calibre_postinstall)

ldd --version
ldd (Debian GLIBC 2.31-13+rpt2+rpi1+deb11u5) 2.31

Got an answer from Kovid in another thread. Calibre switched to requiring the newer glibc after version 6.7.

I was able to install calibre 6.7 on my stock 64bit Raspbian by sticking to that version of calibre and also installing these:

sudo apt install libegl1 libopengl0

[indigo141]

Hi RoninTech, yes I saw Kovid's post after i had installed ver 6.1. I saw a post where another Pi user had installed 6.1 successfully so that was as ambitious as I dared to be. Mostly i wanted the full text search which i believe 6.0 and above have. Perhaps I should try for ver 6.7.

[indigo141]

Actually sudo apt install libegl1 libopengl0 looks much more elegant than installing an unrequired app

On a Raspberry Pi 4, I have a newly created fully updated 64 bit Raspberry Pi OS.

I downloaded https://download.calibre-ebook.com/b....7.1-arm64.txz

then did

sudo mkdir -p /opt/calibre
sudo rm -rf /opt/calibre/*
sudo tar xvf Downloads/calibre-6.7.1-arm64.txz -C /opt/calibre
sudo /opt/calibre/calibre_postinstall

but got the error
/opt/calibre/calibre_postinstall: /lib/aarch64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by /opt/calibre/calibre_postinstall)

I thought that Calibre v6.7 still used glibc_2.31 according to above comments.

Did I do something wrong?

You might want to download the 6.19.1 installer. You should be able to connect to calibre release (6.19.1) and download the ARM64 package.

I suspect you will still need to install the glibc package before retrying the calibre installation

though the sources.json shows 2.70.1 as the current version.

Thank-you, DNSB

As expected, trying this with version 6.19.1 gave the error about `GLIBC_2.34'. But your link lead me to https://download.calibre-ebook.com/6.7.1/, which actually works.
