Could we also have Heirloom NG as an alternative to GNU Coreutils in the future? #80

Open takusuman opened 1 year ago

takusuman commented 1 year ago

I was taking a look at https://github.com/dslm4515/CMLFS/tree/bsd-userland and thought that it would be interesting to also have Heirloom NG as an alternative to GNU Coreutils. These tools were derived from UNIX v7, 4BSD and OpenSolaris, while the majority were rewritten from scratch based on the payloads defined for original UNIX tools. I've been maintaining them in the last two years, and also added a new chroot implementation based on the Solaris 2.5 one. It's the main toolset at Copacabana Linux, so it was also patched to build on musl without any problems. I know we have many problems to solve before, but I just wanted to show it as an alternative.

dslm4515 commented 1 year ago

Yeah, I was dropping coreutils in favor for bsdutils. I'll check out Heirloom NG as well.

I just need a small set of tools to get a chroot running.

Chimera Linux is VERY interesting. Their patches for LLVM is geared towards musl+libc++, unlike Alpine & Void!

Heirloom NG can do the job well, I hope it can help as an alternative. 😄

dslm4515 commented 1 year ago

Looks like Chimera Linux dropped bsdutils and developed chimerautils.

Chimerautils requires:

With optional deps:

Looks like Heirloom NG has less dependencies ... and chimerautils lacks a chroot binary. It provides a chroot. I just didnt see it in sbin

If it matters, i rebuilt bzip2 with CFLAGS="-fPIC' ... no change.

takusuman commented 1 year ago

In any case, you can disable bzip2 with USE_BZLIB=0, or make them build dynamically by commenting the current definition and enabling the other (as the file instructs).

takusuman commented 1 year ago

Looks like Heirloom NG has less dependencies

In fact, way less. You would just need yacc, lex and curses to build it, just disable support for zlib and bzip2. ... And it also provides some utilities that, in GNU Coreutils, would be provided as individual packages, such as cpio and tar.

It's strange to me seeing this error, since it can build fine on Copacabana with musl and GCC... Maybe libbz2 static files aren't installed? @dslm4515

I am using zlib-ng instead of zlib

But still, even when i disable both, similar error:

I am using zlib-ng instead of zlib

That seems to be ok. I'm building it on Copacabana with sortix-zlib and on Ubuntu with the default zlib (dynamically) and both work. I don't think the zlib implementation is a problem.

But still, even when i disable both, similar error

Did you ran make mrproper after disabling them? It's needed to apply the new configuration at build/mk.config. In the worst case scenario, apparently (at least, for now), LLVM can't build Heirloom NG statically linked, so you will need to build it dynamically (just comment out LDFLAGS= -static).

dslm4515 commented 1 year ago

stage1 clang static compiling works. I can build a static binary of libtree:

oops. my mk.config was missing LDFLAGS

takusuman commented 1 year ago

oops. my mk.config was missing LDFLAGS

So maybe this is/was the problem. Try building it again like it was originally: both libbz2 and zlib-ng statically linked plus LDFLAGS= -static. If we can get it working, I can put LLVM in Heirloom NG's compatibility list.

Dynamically? Great!

I went back to the default: static.

So cpio builds fine. Next roadblock: nawk:

Which version of Heirloom NG are you using? I think this was fixed back in this commit: https://github.com/Projeto-Pindorama/heirloom-ng/commit/63793000d599c8902b1e39ca02229e71f93cd9cf

takusuman commented 1 year ago

btw, bmake doesnt work:

I think this isn't exactly a bug, but a question of standards. Heirloom build system was written almost 21 years ago using the "pure" POSIX make syntax, and, if I'm not mistaken, the POSIX syntax isn't compatible with BSD's (and vice-versa).

takusuman commented 1 year ago

i used:

https://github.com/Projeto-Pindorama/heirloom-ng/archive/refs/tags/230120.tar.gz

It's the most recent, you're right. Let me see from where the y.tab.h file is generated and then add the #include <stdint.h> directive to it.

dslm4515 commented 1 year ago

I think this isn't exactly a bug, but a question of standards.

I was hoping to replace GNU's make with bmake to avoid building texinfo for llvmtools

takusuman commented 1 year ago

For now, a quick-n-dirty fix would be to add #include <stdint.h> to y.tab.h (without running make clean or make mrproper) and then running make again.

Maybe you could use a POSIX make implementation, there's some out there. I don't think porting an entire build system would be possible right now.

dslm4515 commented 1 year ago

Yeah. I don't want to use chimerautils...it requires musl-compat-headers, musl-fts, musl-rpmatch, libxo, and meson [which need python... not sure if i should just make python host requirement OR add to cgnutools]

takusuman commented 1 year ago

By the way, isn't GNU's make needed for building the Linux kernel? I think it's a monster that all of us using Linux will need to have installed in our systems at some point.

Well, if it helps, there's this make implementation: https://frippery.org/make/ In theory it can build Heirloom NG just fine.

No wonder make mrproper was so familiar!

I guess i can't ditch GNU make then. Which reminds me... some individuals want to port the linux kernel to ...RUST! Rust is VERY tricky to build...once i just used a prebuilt that the rust developers released for musl...

takusuman commented 1 year ago

Well, the only thing in common between Heirloom's build system (talking both about original Heirloom, Ryan Woodsmall's fork and Heirloom NG) and Linux's Kbuild is mrproper itself --- probably this was a personal choice by Ritter when he was writing Heirloom, honestly I don't know --- besides that, Heirloom's build system don't depend on GNU make, only on a make implementation that follows the POSIX standard.

Oh, you could also try adding -std=c99 to the Makefile.mk at nawk/ directory, more specifically at this line which caused the error:

About y.tab.h, the most interesting part is that it is generated in a one-liner inside the Makefile itself using ed!

awk.g.c: awk.g.y
        $(YACC) -d awk.g.y
        mv -f y.tab.c awk.g.c

Just to make sure i didnt forget any variables, I started over and this time copied mk.config and removed most of the comments for easier editing. Then i edited nawk/Makefile.mk to add -std=c99 :

Does this mean i need ed installed? I don't have it on my host or in llvmtools.

About y.tab.h...

This might be why the generated y.tab.h is missing that header line

takusuman commented 1 year ago

Does this mean i need ed installed? I don't have it on my host or in llvmtools.

ed is part of the POSIX standard, in theory every UNIX-compatible (Linux, *BSD etc) need to have it installed. oed (OpenEd, from OpenBSD) do the job well; I haven't needed it in Copacabana, through, since I wasn't using Heirloom's Nawk. It was used to do more sophisticated changes on files, since POSIX sed doesn't (didn't?) support inserting lines by defaut.

By the way, you would only need it in the host, since Heirloom will provide an ed implementation after being installed.

dslm4515 commented 1 year ago

Well, if it helps, there's this make implementation: https://frippery.org/make/

It wont build dash shell [ POSIX shell implementation i chose] :

 config.status: executing depfiles commands
cmlfs:/mnt/cmlfs/sources/dash-0.5.12
$ pdpmake 
pdpmake  all-recursive
Making all in src
  CC       builtins.def
clang-15: error: no input files
pdpmake: failed to build 'builtins.def'
pdpmake: nothing to be done for all-am

But GNU's make builds dash fine... perhaps, i'll try another POSIX make implementation or patch dash. pdpmake was able to build flex and byacc fine

dslm4515 commented 1 year ago

I'll just build ed for cgnutools in case a host does not have ed

eli-schwartz commented 1 year ago

Yeah. I don't want to use chimerautils...it requires musl-compat-headers, musl-fts, musl-rpmatch, libxo, and meson [which need python... not sure if i should just make python host requirement OR add to cgnutools]

It builds okay with https://sr.ht/~lattis/muon/ , the c99 reimplementation of Meson. No need for python, at least.

Were you able to build it in the end? If yes, which are the versions of the musl libc, Linux kernel and LLVM?

dslm4515 commented 1 year ago

I'm currently testing chimerautils... definitely will not be the default "coreutils" for llvmtools as it lacks chroot... I rather not expect the host to provide a chroot binary.

When I test heirloom-ng, i'll post the versions

dslm4515 commented 1 year ago

And I hit a snag with chimerautils: no install binary.

When compiling bmake under chroot, it uses install to install:

@takusuman, hopefully heirloom-ng has install ?

eli-schwartz commented 1 year ago

chimerautils does have install, not sure what you mean?

dslm4515 commented 1 year ago

I configured chimerautils with this meson invocation:

CC=clang CXX=clang++ \
AR=llvm-ar \
AS=llvm-as \
RANLIB=llvm-ranlib \
LD=ld.lld \

There's your problem, chimerautils is based on FreeBSD and includes the -h <hash> -M <metalog> options for the install command -- this needs libcrypto, which you have chosen to disable.

G'day, Derrick. Sorry for the delay. I'm employed now and I was without time for checking my e-mails until now. Yes, it have install. If you want a custom destination directory, use ROOT (eg.: ROOT=/tmp/heirloom gmake install)

dslm4515 commented 1 year ago

Damn. I accidentally executed rm -rf /* instead of rm -rf ./* [while in chroot] and destroyed my CMLFS build.

I guess its good time to test heirloom-ng as the coreutils for chroot.

# Curses library. Change to -lncurses if necessary. Caution: Some gcc
# setups on Solaris are broken so that ncurses headers are used during
# compilation, but the system libcurses is used for linking. This will
# usually lead to segmentation violations. The easiest fix is to write
# something like -L/path/to/ncurses/lib/directory -lncurses here.

# The 4.4 BSD curses library, which is still supplied with NetBSD 2.0,
# does not supply our needs. Use -ltermcap instead and add -DUSE_TERMCAP
