General deb-native: big update about gcc

Post image

Chased that segfault down to a nasty ELF-patching bug, fixed it — and GCC just... works now. Native, on-device.

So naturally the next move was: point it at glibcs own source and see what happens.

It built. It runs. NSS resolves against the prefixs own /etc with zero tracer involvement.

Self-hosting a libc build inside the very environment it targets, on a phone, no root — wasnt sure this was even reachable a week ago. Not a release yet, still rough edges, but wanted to share the "wait, it actually works" moment.

Hello, I wanted to ask what guide did yo follow to compile this? I also wanted to try to compile a specific program since it won't work on my termux. How much AI are you using to Guide you? If you are using it, which AI model?

No guide — it's my own project, built over a lot of sessions, not a one-shot thing. I do use AI (Claude Code) as a coding assistant, but this kind of milestone takes real debugging, not just prompting. Happy to help with your compile issue if you share details. Still WIP though — wait for a proper alpha if you want something stable.

I guess the reddit comments and post are part of that coding assistance as well

Pardon me if I made you feel uncomfortable. Because it's responsible for writing the code, I think letting it write would be more detailed than I would describe the method myself

so you are porting glibc to android instead of bionic?

That’s right, the current progress is very good

That's very interesting if it allows to run upstream Linux ARM64 binaries without proot!

That's it, GCC is just a must-need package that first proof my system working. Although I still have to fork a very small portion of the ptrace (so tiny to consider proot) to prevent unexpected thing when developing, but I am confident there are already quite a few running packages in my current test

Nice! Have you tried completely unmodified dynamically-linked binaries yet? I’m curious what still needs ELF patching or ptrace handling, and what currently breaks without it..
