far2l does not build with python on ubuntu 24.04 lts

[faerot]

I have tried last release 2.6.3, it did not build due to some xerces error
I have tried master, and it fails to build

I have configured cmake with:
cmake -DUSEWX=no -DPYTHON=yes -DCMAKE_BUILD_TYPE=Release ..

[faerot]

Also question: why far2l that comes via apt install is not built with python? python is essential part of debian based distros, so why not building it with python support there?

[akruphi]

@faerot you can try build with system python via -DVIRTUAL_PYTHON=python3 (brief details see in https://github.com/akruphi/far2l/wiki#plugins_py )

About python problems lets ask far2l python creator @m32

[faerot]

@faerot you can try build with system python via -DVIRTUAL_PYTHON=python3 (brief details see in https://github.com/akruphi/far2l/wiki#plugins_py )

Does not work either. With -DVIRTUAL_PYTHON=python3 it has this kind of errors:

I have installed python3-cffi, python3-pcpp, python3-debugpy, but not adbutils, since there is no official package in the repository and I don't plan to use android plugins. Could it be because of adbutils?

[m32]

python3 -m venv env /devel/bin/python3
will create a virtual python environment, during the installation "virtual pip3" is also set up. After such python installation you can manually install missing packages, then these are the correct parameters for cmake:

-DVIRTUAL_PYTHON=/devel/bin/python3/bin/python
-DVIRTUAL_PYTHON_VERSION=3

This cannot be the system python interpreter.

This speeds up building far2l and allows you to use your own virtual python instance as well as using a package like adbutils.
If you use the --with-python parameter, the virtual python will be created automatically during program building

[faerot]

I don't want to mess with various venvs because frankly I am not really sure what exactly the problem is. I am just trying to build far2l with python as stated by the documentation on front page here. Is the described way to build far2l with python is obsolete or makefiles are broken? Need to either fix the makefile or update the documentation.

[m32]

Before building with python enabled install requred package:
sudo apt install python3-venv

and build as described in README.md, eg:
cmake .. -DCMAKE_BUILD_TYPE=Debug -DPYTHON=YES

will create virtual env in install/Plugins/python/plug/python with required python packages

[faerot]

Unfortunately installing python3-venv did not help, I have deleted _build dir contents before trying again just in case, but error is pretty much the same.

I forgot about cffi requirements:
sudo apt install libffi-dev

[shmuz]

@m32
I have working Python plugin on one of my virtual machines.

However I still can not install it on the other (Linux Mint 22) machine.

The following commands were executed successfully:
sudo apt install python3-venv
sudo apt install libffi-dev

But when I run cmake .. -DPYTHON=yes I get the following:

[shmuz]

When I tried again to install libffi-dev the response was:
libffi-dev is already the newest version (3.4.6-1build1)

Could the libffi-dev version be a problem?

[m32]

@shmuz

This is something related to cmake - my is 3.25.1 on debian 12 or python3-dev

Python3_INCLUDE_DIRS is available after:
find_package(Python3 COMPONENTS Interpreter Development)
if(Python3_FOUND AND Python3_Development_FOUND)
...
else()
echo Missing Python ....

[shmuz]

@m32
I got some additional help on a telegram channel and finally the plugin was installed successfully.

The list of required libraries to be installed is:

• libpython3-dev
• libffi-dev
• python3-venv
• python3-cffi
• python3-pcpp

It would be helpful to place this list in some easily visible place.

[m32]

these are downloaded while building plugin:
python3-cffi
python3-pcpp

the cffi package must be compiled from source, otherwise there may be problems with running the plugin

[shmuz]

Thank you. Indeed I removed these 2 packages and the plugin still builds OK.

But there is an error (that does not prevent the plugin from being built):

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed.
This behaviour is the source of the following dependency conflicts.
yt-dlp 2024.4.9 requires websockets>=12.0, but you have websockets 10.4 which is incompatible.

[atolismesh]

@m32 Grzegorz,
please note that some of your .py plugins unconditionally do
import debugpy
Some - conditionally.

if 0:
    import debugpy

But it (python3-debugpy package) isn't installed by default . And not mentioned in requirements.
Thanks

[m32]

@atolismesh

debugpy, adbutils, cffi, pcpp are instaled while building python plugin - i'm sure CMakeLists.txt:493 line
and prebuild.sh lines 19 and 20

python plugin requires only python development package nothing more, rest is installed from pypi

[m32]

@shmuz
yt-dlp = youtube downloader ?

is not used by python plugin, can you provide more context ? log, ...

I installed a fresh Linux Mint 22 and rebuilt far2l with spdlog problem in colorer and the process looks like in debian.

yt-dl ? - I don't know what it's about at all

my script:

#!/bin/bash
cmd_installdeps() {

libneon27-dev libarchive-dev cmake pkg-config g++ git \
libpython3-dev python3-venv libffi-dev libspdlog-dev
}

cmd_gitclone() {
git clone https://github.com/elfmz/far2l
}

cmd_cmake() {
pushd far2l
if [ ! -d build-std ]; then
    mkdir build-std

@m32 , I don't have a clue about what that yt-dl is.
And it is possible that something is wrong with my system (though I don't remember doing something unusual with it), It is not my main Linux system, it's one of several Linuxes that I use for testing.

I don't consider it as a major problem and even don't have plans to investigate it.
So, thanks for your help, it is appreciated.

[faerot]

I forgot about cffi requirements: sudo apt install libffi-dev

Indeed, that helped to build it. README needs to be updated to include libffi-dev requirement not to waste your time every time someone will try to build far2l with python :)
