#binutils

GNU #Binutils BFD Linker joins the linker performance challenge. Thanks to Michael Matz of

@thindil That's what I assume as well, once I'm done with the toolchain, architecture-specific differences should be rare (if encountered at all). 🙏

Just finished the cross-version of #glibc for all archs. Two more (#binutils and #gcc) to go for the FULL cross-toolchain. That will be the goal for today, the native toolchain maybe tomorrow 😎

This feature-branch finally starts to look somewhat promising, just added native #Linux #GNU #binutils for #FreeBSD's #Linuxulator 😎

linux_base-dirs is a tiny metaport just owning ${LINUXBASE} and a few essential subdirs.

Everything prefixed "lxcross-" is part of the cross-toolchain and installed to ${LXCROSSBASE}, defaulting to ${LOCALBASE}/linux-cross.

Everything suffixed "-bootstrap" is some minimal/temporary port needed to build the full cross-toolchain and installed to ${LXBOOTSTRAP}, defaulting to ${LXCROSSBASE}/bootstrap.

Everything prefixed "linux-" is Linux-native and installed to ${LINUXBASE}.

linuxheaders44 just contains the headers from Linux-4.4.x, installed to ${LINUXBASE} but coming with a slave-port installing to ${LXCROSSBASE} for the cross toolchain.

Next step: GNU gmp! Let's see 😎

I'm carefully optimistic now again 😎

After first building very basic/limited "-bootstrap" versions of binutils and gcc into a separate prefix, it seems I could finally build a complete #GNU cross (#FreeBSD -> #Linux) toolchain, including #binutils, #glibc and #gcc (with libstdc++). This final cross gcc at least passed the most basic sanity check -- it successfully compiles an empty program 🙈

Now doing a bit of cleanup and then trying whether this beast is able to build the *real* (native) glibc for a new #Linuxulator userland 😎

@jhx I really dislike C++ for a variety of reasons, but that's not relevant here I guess 😎

Right now, #binutils *would* finally build fine, but missing #zstd support.

Trying to build facebook's #zstd first, running into yet another roadblock. For *some* reason, the build doesn't see the definition of "std::mutex" although it looks like the headers installed by #gcc's libstdc++ have it.

Not sure whether it's time to give up yet 😞

@jhx Won't be the last hack. Just added a similar wrapper for C++, yes, parts of #GNU #binutils use C++.

Part of my issues is mixing some cross-toolchain with #glibc already installed "natively" where it should be.

But I get the impression a *huge* part of the problem is these GNU build systems trying to be super clever and detect anything for any possible system automatically -- which explodes in your face when your scenario is "very unusual", like here, trying to cross-build the toolchain on #FreeBSD targeting #Linux 🤯

The #gentoo #sparc builders are disabled for now because the worker had become a little too unstable.

We hope to get it back soon because it is doing a lot of builds for #Sourceware projects.

#elfutils, #libabigail, #bzip2, #debugedit, #gccrust, #binutils, #gdb, #gcc, #systemtap, #glibc, #gnupoke.

Ok let's port #binutils to the unsp CPU used in the #VTech #VSmile !
Apparently this starts by building a version of autoconf from 11 years ago, otherwise you can't regenerate the configure scripts (which need to be modified to add a new target)

Prepare for fun, excitement and inspiration! GNU Tools Cauldron 2023 in Cambridge UK, September 22-24!

How to make life hard for package maintainers in #Linux #distributions:

Just provide a patch instead of directly releasing a new version of foo, when it starts to misbehave with a newly released version of bar, which leads to build errors in foobar.

That's bad, as package maintainers of several distros now need to discover and apply the patch (& later revert) it.

foo in this case is #pahole: https://src.fedoraproject.org/rpms/dwarves/c/5acd1ae2c9ddde3cf3470047265470586a9d6744?branch=rawhide
bar was #binutils 2.40
foobar is #kernel: https://koji.fedoraproject.org/koji/getfile?taskID=97533096&volume=DEFAULT&name=build.log&offset=-4000

A warning, certainly to those in the #illumos and #Solaris communities, but perhaps wider, that #binutils 2.40 should be considered toxic.

Running gstrip(1) on a binary renders it completely broken.

Will be reverting to 2.39 in our pkgsrc tree.

Just saw this line in the NEWS file of #GNU #binutils:

* DCO signed contributions are now accepted.

DCO is the Developer Certificate of Origin, which is essentially the "Signed-off-by:" header used in git commits for the Linux kernel:
