A script for patching toolchains to resolve glibc requirement issues on distros with old glibc packages. ( DEPRECATED ) ( FUNCTIONALITY MOVED TO https://github.com/Neutron-Toolchains/antman )

the script no longer works for some reason, it might be because arch did some housekeeping on their repos but i have no clue honestly. i use the script alot, can you please look at it again that would be very helpful.

Sure, I will look into it... It would be helpful if you could provide some more details about the issue or error logs.

mhm of course! i have this script running on a ci right now, I'll send you the output logs.
in the meantime, the link you use to download patchelf from the aur: https://archlinux.org/packages/community/x86_64/patchelf/download/
that returns a 404, i found out something cool. turns out that patchelf now lives at: https://archlinux.org/packages/extra/x86_64/patchelf/download/
edit: logs! https://github.com/itsHanibee/kernel_xiaomi_chime/suites/13138951417/logs?attempt=1

Thanks for the quick response, It seems like the change in link path has caused the script to break. I will try to update the link ASAP.
Btw, I have noticed that you use antman to sync the toolchain, I would recommend to use it to patch toolchain for glibc' issue as well, it's the same but simpler script integrated into antman, Introduced in this commit. You can patch toolchain for glibc issue by running ./antman --patch=glibc .
Note that the link in antman must also be updated, So currently it would be broken as well.

oooo that actually sounds super cool, i didn't know that! will definitely use next time. also if you haven't fixed it yet can i do a quick pr on antman? it'll be a quick oss contribution and it seems like it's pretty simple to do!

i forked this script in the meantime and i just updated the link and it works perfectly fine so that's all there is to change I'm pretty sure. :)

EDIT! you pull patchelf from nixos and the package seems to exist and everything looks like it'll work fine so there's nothing to fix! the aur packages are fine too 😄. good morning and have a great day!

Oh right I completely forgot that I use NixOS binaries in antman, I did it because NixOS release binaries are statically linked against musl libc, This allows the patchelf binary to be executed on platforms with very old glibc where ArchLinux's patchelf which is linked against newer glibc won't work.

So I think there is no changes required to be made in antman and users of this particular script can also safely migrate to antman.

Hi. I am trying to build my Android Kernel (SM8350 Kernel https://github.com/glikched/android_kernel_samsung_sm8350). But it seems something needs to be also patched.

Error:

This script's functionality has been moved to antman utility and since v2.4 update it can handle glibcxx patching along with glibc. Please migrate to antman utility for patching your toolchain.
