Hi,
I'm updating my development environment with the latest SDK (2.14), and MCUXpressoIDE (11.8.0) however the installer fails due to a missing package libpython3.8.
Debian 12 is using python 3.11, version 3.8 is no longer available.
E: Sub-process /usr/bin/dpkg returned an error code (1)
Reading package lists... Done

E: Unable to locate package libpython3.8
E: Couldn't find any package by glob 'libpython3.8'
MCUXpresso is running and compiling, but when debugging is started it fails:

Is there a fix available for this issue ?

Python 3.8 installation on Debian 12 :
1. install prerequisites
sudo apt update sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libsqlite3-dev libreadline-dev libffi-dev curl libbz2-dev liblzma-dev
2. dowload python 3.8 source code & untar:
curl -O https://www.python.org/ftp/python/3.8.9/Python-3.8.9.tar.xz
tar -xf Python-3.8.2.tar.xz
3. configure for compilation:
cd Python-3.8.9 ./configure --enable-optimizations --enable-loadable-sqlite-extensions
4. start make
make -j 4
5. install
sudo make altinstall
6. test
python3.8 --version
Thanks ! - MCUExpresso DOES work on Debian Bookworm!
Hi both of you,
It appears that by installing python 3.8 on my Ubuntu 22.04, it works. I seems that the software look for it and do not use python3.10 that was installed by default.
Best regards,
Thomas
Hi Chris, Hi Miguel,
I have the same problem on MCUxpresso under Ubuntu22.04 LTS...
Hi Thomasfaguet,
That's strange, after my problems with Debian I did a test on the latest Ubuntu 22.04.3 LTS and it worked for me.
It was a fresh install of Ubuntu, maybe that made the difference ?
Best regards,
Chris
1 year later...
Same happening here while trying to install IDE 11.9.1 running Linux Mint 23.1 (Ubuntu derivative), pythonlib3.8 doesn't even exist in the distro repositories, so I can't install this library (at least directly).
Any hint?
Hi Miguel,
You are right, my fault, it used to work in the past which seemed to be a coincident. I managed to get it working by building / installing python3.8 manually.
Best regards,
Chris
