Cannot run texlive context: permission denied

Cannot run texlive context: permission denied

[Reza Housseini]

Hi Guixers

When running context inside

  guix shell texlive-context --container

I get the error

   sh: /gnu/store/l4r1y73grs5mvx2jz1hndwgnxcgys9sj-profile/bin/context: 
Permission denied

What is the reason for this?

Thanks for your help.

Best regards
Reza

I'm also experiencing this same issue on two different installations of
Guix.

Running `context` directly yields the same result as Reza's. However, I
was able to successfully run the `mtxrun` binary and to generate the
database files using `mtxrun --generate`.

While `context` is unable to execute, `mtxrun --script context` throws
the following error:

   unknown script 'context.lua' or 'mtx-context.lua'

I'm here to tell you that I found a working workaround for making
ConTeXt work through `mtxrun --script context`.

Create a "texmf/web2c/texmfcnf.lua" file (and preceeding directories)
under your user's home directory and add the following:


    return {
      content = {
         variables = {
           TEXMF = os.getenv("GUIX_ENVIRONMENT") .. "/share/texmf-dist"
        },
      },
    }


That should be enough to get the ball rolling. Note however that running
`context` independently from `mtxrun` continues to fail.

These changes should probably be added to the build derivation, it seems
that Guix' non-standard filesystem don't work well with TeXLive's
default settings.

I think it is fixed in "tex-team" branch.

Thank you Nicolas,

I tried out your changes, and although the "permission denied" error no
longer shows up, running context in the terminal (user home intact,
i.e. without my previous configuration hack) yields the following
message:

It seems that mtxrun fails to find either files, the same message will
also appear if invoking context through mtxrun via the --script flag.

Could you trying clearing out your cache, i.e.
"~/.texlive2023/texmf-var/"? It may contain bogus information.

Nevermind! I misread your error message; your cache seems OK.

I think you created an incomplete environment, i.e., you used something
such as:

  ./pre-inst-env guix shell texlive-context

But `texlive-context' alone is not sufficient. You need at least
a scheme or a collection in this environment, as mentioned in the
manual, or, if you really want to be minimal, `texlive-bin'. E.g., in
decreasing size:

  ./pre-inst-env guix shell texlive-collection-context

     or

  ./pre-inst-env guix shell texlive-scheme-minimal texlive-context

     or

  ./pre-inst-env guix shell texlive-bin texlive-context

Yes, you're totally right.

I used texlive-scheme-context and texlive-collection-context and both
worked without a problem. I took a .tex file for a spin just to make
sure compilation worked without issue, and as you'd expect, all was
good.

Thank you so much for fixing this, Nicolas.

Hello there,

I've been following the master branch ever since the changes you've
introduced and I was wondering whether there was a particular reason
they haven't been merged yet.

If additional testing is required, I'd be happy to help out, but as I
previously pointed out, ConTeXt is working properly now.

Kind regards,

Branches are merged in a FIFO order. Two branches are currently located
before "tex-team", as pointed out at <https://qa.guix.gnu.org>. I think
"gnome-team" will be merged very soon. I have no idea about
"core-updates".

Meanwhile, I'm polishing "tex-team" so it will be absolutely fantastic
(or utterly broken) once merged ;)

Thank you for your feedback! For now, waiting is the only thing to do,
however.

I really appreciate the explanation, thank you. I was taken aback by the
transparency of the whole process, it looks like a really well-polished
experience.

I'm sure it'll be great.

Gotcha, thanks!
