Can pyinstaller work with any recent version of ubuntu ?

[peter1john]

HI,

I am new to this and while exploring how to create executable for python script i found pyinstaller is very popular and from command line installed this package and started creating executable it is working fine on my laptop. But while going throgh documentaion i found below infromation, if any of below three situation comes then we need build for that platform,

a different OS

a different version of Python

a 32-bit or 64-bit OS

My aim is to create executable for atleast 18.04 and 20.04 with any of python package.

Is there any way to crack this?

Thank You.

See docs. tl;dr is that if you build on 18.04 it will usually work on 20.04 whereas it will generally not work the other way around. It does depend on the complexity of your dependencies and how many versions you consider recent. There are always exceptions though -- I vaguely recall it being impossible to support many versions in one build when PyQt is a dependency for example.

@bwoodsend i tried both steps, appears to be issue with pip package.
resolved with help of https://github.com/pypa/pip/issues/5599

Is it possible to statically link with glibc while creating executable, by assuming it wont be an issue regardless of ubuntu version as it will be part of executable itself ?. Is my understanding correct ?

That's the idea behind static linking, yes.

However, PyInstaller does not compile shared libraries and other binaries - it just collects them from the build system. So even if you statically compiled PyInstaller's bootloader (instead of using the pre-built one), you would also need to somehow ensure that your whole python environment was built statically.

staticx emulates static linking for binaries that are originally dynamically linked, so I'd say that's pretty much your only option in this regard.

Thank You @rokm, let me explore bit more on it.

But now this issue resolved, as mentioned earlier i tried to compile on lower version of ubuntu which we are going to support and it is working on all higher versions of ubuntu. Thank You all for helping me to resolve this issue :)
