Hello,

In an attempt to verify whether bug 48064¹ (”texlive-* packages fail to 
build non-deterministically”) is fixed by the current TeX Live version, I’ve 
been working on updating it to version 2021.1².

Unfortunately I ran into a bootstrapping issue: texlive-latex-base now 
depends on texlive-latex-l3kernel, otherwise its build fails with:

LaTeX2e <2020-10-01> patch level 4
! LaTeX requires expl3.

The problem is that if I add texlive-latex-l3kernel to the propagated-
inputs list of texlive-latex-base, then a dependency loop is formed since 
texlive-latex-l3kernel uses the texlive-build-system, which adds texlive-
latex-base as an implicit input. And if I understand thing correctly, 
l3kernel does indeed need some form of TeX or LaTeX in order to run
`source/latex/l3kernel/l3.ins`.

I tried to “cheat” and added the build argument
`#:texlive-latex-base ,texlive-bin` to texlive-latex-l3kernel (since 
texlive-bin doesn’t depend on texlive-latex-base), but then I get an error 
about not being able to find `luatex.fmt`.

Looking around the web, I found this answer:

Does anyone have an idea how to break this dependency loop? Do we need to 
have a package definition for a pre-2019-10 version of LaTeX just to build 
texlive-latex-l3kernel, and then use that as a dependency for the actual 
texlive-latex-base package?

The only alternative I can think of is trying to build a minimal version of 
2021.1 LaTeX which somehow doesn’t use expl3 so that it can be used to 
build texlive-latex-l3kernel. But that is above my very superficial 
understanding of TeX and LaTeX. And the quote I pasted above doesn’t look 
very encouraging.

If anyone wants to have a look at what I have so far, I pushed my patch to 
branch “bug-48064-texlive-2021” at https://gitlab.com/bauermann/guix .

I’m pursuing this option. I took the definition of texlive-latex-base from 
the master branch (which doesn’t depend on LaTeX3) and added it to my 
branch as texlive-latex-no-l3 (with a few minor changes to get it to build 
with texlive 2021), and used it as a dependency to build texlive-latex-
l3kernel.

This worked! Now texlive-latex-l3kernel builds correctly, and the build of 
texlive-latex-base is attempted (instead of just causing Guix to max out 
its heap while trying to process a dependency loop, as it was doing 
before). But the build fails when generating some latex formats – a problem 
I’m still investigating.

But this is progress nevertheless. :-)

I just force-pushed this branch with my current version of the patches.

Thumbs up for working and figuring things out for a texlive 2021
upgrade!

Thank you,

Thank you! I was just going to report on recent developments.
It turns out that using an older LaTeX to build texlive-latex-l3kernel 
isn’t necessary.

I decided to ask on the TeX Live mailing list about the bootstrap problem¹ 
(not sure why this didn’t occur to me earlier). It turns out it’s not a 
real circular dependency, it just appears so because of Guix packaging.

It’s possible to build texlive-latex-l3kernel with IniTeX (i.e., by calling 
`pdftex -ini` or `tex -ini`) and docstrip, without any format loaded.

So I made some changes to texlive-build-system to that, and it worked. By 
which I mean: the texlive-latex-l3kernel package builds, and the texlive-
latex-base build is attempted and fails in the same way as it was failing
when I sent the last email, when generating latex formats. I think I’m 
missing some file(s) with definitions for LaTeX macros, but I don’t know yet.

I pushed a new branch “bug-48064-texlive-2021-l3kernel-initex” to my GitLab 
repo at https://gitlab.com/bauermann/guix.git with two patches implementing 
the new approach.

It was worth it to ask :-).

I had a cursory look at the commits; they look good to me!  And the
commit messages are very useful in understanding the hows and whys.
Make sure to send them to guix-patches@gnu.org after you are satisfied
with the result!

Happy hacking,

Maxim

Thank you for having a look! I will certainly submit themt o Guix when I 
manage to get a working build of TeX Live 2021.

Hello,

TeX Live situation update:

I was able to build the main TeX Live packages with  source tarball version 
20210325 – the latest on the historic TeX Live FTP site – and subversion 
tag texlive-2021.3 – the latest tag in the TeX Live repo.

Unfortunately issue 48064¹ still happens. On the bright side, I found a 
workaround for it that also works with TeX Live 2020 currently in core-
updates I will submit the patch with the workaround as soon as testing 
finishes, hopefuly later today.

I will also separately submit patches updating TeX Live to 2021 after I 
build all of the texlive packages, hopefuly in a couple of days.

Thiago

Unfortunately the patch I was testing which just changed some packages to 
build with pdfTex didn’t work and I ended up sending a patch which simply 
switches all packages to build with pdfTeX instead of LuaTeX. It’s 
available on the issue page¹. It didn’t show up on the guix-packages 
mailing list – not sure why.

Ludo reported the problem to the LuaTeX development mailing list (thanks!) 
and a developer there already mentioned that he would work on it ASAP.

I just finished working on the TeX Live 2021 update. The patches are 
available on issue 49408².

It updates all packages matching “texlive*” but doesn’t add any new one. If 
I should add new packages, please let me know. In that case I would also 
need criteria to know which new packages to add. :-)

At this point I don’t see anything else related to TeX I could be doing. 
Feel free to let me know if there’s anything.

> Sounds good!  Thanks for the update about your progress.

Thanks for your feedback!
