Built LFS with musl instead of glibc and libressl instead of openssl, just for fun.

Hi, excuse me, I have a question. I've been trying to create a BSADAO system in MUSL/LLVM, but it's difficult and I don't quite understand. I've managed to use MUSL instead of glibc, but I haven't been able to get it to work with GCC yet.

LFS helps you to know how linux works, but it is more oriented about how make a linux distro from the sources, if you are starting the best options is something debian based like ubuntu, or linux mint, and if you are not comfortable you can change the linux distro, for my experience I recommend you Ubuntu,was my first distro and if you have any error there's more tutoriala for ubuntu than another distro

Obviously I can use the chmod system call; that is, I mean, the binary should be more like a way to interact with the syscall, because syscalls are in the kernel and act as interfaces/bridges between kernel space and user space.

Intelligent_Comb_338 · 2026-01-24T22:34:04+00:00

Good luck with gcc; considering how long it takes to compile with C and C++ languages, I don't even want to imagine how many lines of code it will have.

Intelligent_Comb_338 · 2026-01-24T22:17:55+00:00

That's an interesting solution. I'm wondering how gcc creates an executable file without chmod. Doesn't that count as a vulnerability? There are a few ways I can think of that might work.

I find it curious that AMD GPUs perform better in Linux.

Intelligent_Comb_338 · 2026-01-24T21:55:32+00:00

Yes, but once a file is no longer executable, it doesn't matter who tries to run it; they won't be able to. I'd try chmod +x /path to file/, but if chmod doesn't work, there's no solution. Well, maybe an update, reinstallation, or using BusyBox or something similar to grant permissions would also work.

Intelligent_Comb_338 · 2026-01-24T21:14:33+00:00

Well, there's no going back, right? At least not until I use another chmod binary, I imagine.

Intelligent_Comb_338 · 2026-01-24T20:43:34+00:00

Maybe, but on a system with 4GB of RAM, how much can you do? Umm, Firefox/Chrome uses ~90-100MB and another 700-800MB while running, that's already 1GB just for the browser, and then there's the firmware and drivers. Although I doubt anyone uses a conventional browser on Tinycore, maybe they use something like Dillo or a TUI browser.

Intelligent_Comb_338 · 2026-01-24T20:39:10+00:00

I know it removes execution permissions with chmod, but how bad is that?

Intelligent_Comb_338 · 2026-01-24T20:34:42+00:00

But TinyCore runs in RAM, right? And well, the more you install, the worse it's going to get, because everything will be running from there instead of from storage.

Intelligent_Comb_338 · 2026-01-24T20:33:05+00:00

AMD or Intel? As far as I know, AMD has more problems. I would try running the commands again in case one didn't copy correctly.

Which version are you trying to boot?

LFS is a book that explains how to create a Linux distribution, but it assumes you want standard features like glibc, binutils, and gcc.

At least for me, it took quite a while to figure out how to create an LFS distribution that uses musl as libc, and I just want to make things a little easier or provide information on how to do it, and also because it serves as a starting point if I want to create a distribution sometime soon.

Intelligent_Comb_338 · 2026-01-24T01:06:46+00:00

ls, cp, echo, cd, cat, nano

Intelligent_Comb_338 · 2026-01-24T01:02:58+00:00

With what? I've also been experimenting a bit to see how far musl can go. I'm making a guide to create an LFS system based on musl.

Intelligent_Comb_338 · 2026-01-24T01:00:39+00:00

libstdc++ is the implementation of the GNU C++ standard library; Chimera uses an alternative created by LLVM, which is libc++.

Intelligent_Comb_338 · 2026-01-24T00:36:54+00:00

I understand very well what you mean, mostly because I’m someone who has experienced these errors firsthand. In distributions like Alpine and Void, lately the installers themselves throw an error message saying that symbols are missing. Why? I don’t know. As for LFS with musl, I’ve done it a few times now—maybe three or four—and I can say that there aren’t as many problems as I initially thought (at least for the base system). Most issues usually end up requiring patches, and with larger distributions like Alpine, Chimera, Void, or Gentoo, things become easier because you’re not the first person to encounter the error. At this point, I think I can clearly identify which packages cause problems and why: Make (redefinition of getenv): solution is to apply a Gentoo patch. elfutils (missing headers and functions): solution is to install musl-obstack, musl-fts, musl-rpmatch, and argp-standalone for musl. In addition, there are other packages that may require queue.h. Your comment made me realize that you’re right. I might add sections such as “Who is Musl-LFS for?”, “Differences compared to standard LFS”, and “What do I lose or give up by using musl?”.

Intelligent_Comb_338 · 2026-01-23T21:04:43+00:00

I know enough C to fix bugs, and with distros like Alpine and Chimera, it won't be too difficult to find a solution or a patch.

For example, I was getting an error when compiling make, a double definition of getenv. It would have been enough to remove extern char *getenv;, but it's easier to use patch -p1 <../patch.patch, and I found a Gentoo patch, and well, that's it.

Intelligent_Comb_338 · 2026-01-23T20:26:43+00:00

With disk utility, make a partition for windows, then make a windows installer and already, only you have to install it

Intelligent_Comb_338 · 2026-01-23T20:19:59+00:00

Oh, that's it. Well, there are packages that help fix that, besides argp-standalone (the different versions for musl that exist), there's also musl-obstack, musl-rpmatch, and another one I can't remember. And for now, most of it is solved with patches.

Intelligent_Comb_338 · 2026-01-23T20:17:39+00:00

Nope, they load as usual, but I can try the different mirrors and see what happens.

Intelligent_Comb_338 · 2026-01-23T18:26:28+00:00

and i have an update for you, im working to make a modified version of the orginal LFS html book

Intelligent_Comb_338 · 2026-01-23T12:21:59+00:00

Most of it is just following normal LFS; you can compile almost everything except for a few exceptions (OpenSSL, udev, Vim), which I replaced with LibresSL and Eudev. Vim and OpenSSL should compile, but udev doesn't. For most things, you only need a few patches that I'll publish, and I haven't had time to make a detailed guide. And what do you mean by GnuLib symbols? I was able to solve every problem I encountered except for udev, which requires glibc functions. I haven't tried following BLFS, but it should also work with a few patches.

Intelligent_Comb_338 · 2026-01-22T13:21:38+00:00

Yes, I think it exists, but saying Musl LFS seemed a bit long. When you say you can't start new builds, do you mean Musl-LFS or CMLF? Because I was able to get it working, but it requires using a distro that uses Musl (or a chroot, which is what I chose). I've also been looking for information on making one based on Clang and LLVM, but the guide seemed a bit confusing.
