Using system libraries

[phpaiva]

I can't find a way to compile just the interpreter and the project, without the libraries in the system.

I mean, to use the /usr/lib directory as usual, not packing into a standalone or by a dedicated folder with clones of the libraries. I want to take advantage of the shared libraries in the same way the application works without being compiled with pyinstaller.

Thanks in advance.

There is Analysis.exclude_system_libraries() that might do the trick: https://pyinstaller.org/en/stable/spec-files.html#posix-specific-options

But on the other hand, if you aren't looking to create a stand-alone bundle, why use PyInstaller in the first place?

Just to cover the source code a little. I work on OpenWRT and MIPS architecture. Getting an obfuscator or compiler up and running has been an impossible challenge with the exception of pyinstaller. I wanted to make a text obfuscator since there are no useful obfuscators for complex projects, but I realized that the work was getting really complicated and I don't have time to overthink this either.

So I settle for covering the code a little to prevent hands with very little knowledge from trying to degenerate the spirit of my initiative, which at the moment I am not interested in spreading too much.

I tried to test what you proposed but it still going for the "_internal" folder:

Here is the .spec file:

Even with Analysis.exclude_system_libraries(), you cannot completely get rid of _internal directory. And python shared library should still be bundled (and the stdlib binary extensions as well)... If you want to get rid of everything, you will need to look into customizing bootloader code.

You might as well just python -m py_compile then remove your source code and leave it at that then. That's the only function of PyInstaller you'd be using.

hi i am also trying to obfuscation can u pls help me on this

[bwoodsend]

No, obfuscation is not something we want anything to do with.
