Missing libudev.h

[roygrubb]

On a fully up to date Raspberry pi 5 running RaspiOS bookworm, f3write and f3read compile and run correctly.

When I try to compile f3probe and f3fix with
sudo make install-extra
I get this:

cc -std=c99 -Wall -Wextra -pedantic -MMD -ggdb -c -o libdevs.o libdevs.c
libdevs.c:21:10: fatal error: libudev.h: No such file or directory
21 | #include <libudev.h>
| ^~~~~~~~~~~
compilation terminated.
make: *** [: libdevs.o] Error 1

I then tried on Ubuntu 24.02, also up to date, running on i7-3770 and f3write and f3read worked but trying to compile f3probe and f3fix gave the same error.

I tried
sudo apt-get install libudev-dev
but that reported
The following packages have unmet dependencies:
libudev-dev : Depends: libudev1 (= 252.38-1~deb12u1) but 254.26-1~bpo12+1 is to be installed

I found this, https://github.com/systemd/systemd/tree/main/src/libudev
but don't know how to install it. Forgive my ignorance.

Can anyone offer advice please?

Thanks

Could you try the steps in section The extra applications for Linux of the README file to see if they address your problem?

Thank you

The result is as follows:

sudo apt-get install libudev1 libudev-dev libparted-dev
Reading package lists... Done

libudev1 is already the newest version (254.26-1~bpo12+1).
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

libudev-dev : Depends: libudev1 (= 252.38-1~deb12u1) but 254.26-1~bpo12+1 is to be installed
E: Unable to correct problems, you have held broken packages.

I then found https://thelinuxcode.com/fix-broken-packages-raspberry-pi/
This gives many steps to help fix the held broken packages problem as follows:

sudo apt --fix-missing update
sudo apt --fix-broken install
sudo apt install -f
sudo apt full-upgrade
sudo dpkg --configure -a
sudo dpkg -l | grep ^..r
sudo apt clean
sudo apt update
sudo apt full-upgrade

I ran these step by step, trying
sudo apt-get install libudev1 libudev-dev libparted-dev
each time, but after even the last step, the same error message appears:

The following packages have unmet dependencies:
libudev-dev : Depends: libudev1 (= 252.38-1~deb12u1) but 254.26-1~bpo12+1 is to be installed
E: Unable to correct problems, you have held broken packages.

Would you recommend
sudo apt purge libudev1 libudev-dev libparted-dev
followed by reinstalling?

I'm worried this could break my system....

Thanks again

I have since done:
sudo apt-get install --reinstall libudev1
which was OK, then:
sudo apt-get install --reinstall libudev-dev
which gave:

Without much hope, I tried
sudo apt-get install --reinstall libparted-dev
but the result was the same.

libudev1 (= 252.38-1~deb12u1) but 254.26-1~bpo12+1 is to be installed
Looks as if libudev1 is an earlier version (252.38-1) that does not match libudev-dev (254.26-1) and libparted-dev
