yes, I agree it should be feasible.

I think Luca has just created the zeromq
https://readthedocs.org/projects/zeromq/  project.
RTD allows to add as many maintainers as needed to a single "project" (like
zeromq)... AFAICT all maintainers have same rights/permissions.
I think it would be best to have all libzmq maintainers added there to
ensure there will be always someone with the rights to update/tweak config
settings also in upcoming years.
And for sure I can be there to help as I can.

Thanks,
Francesco

RTD provides a "custom domain" aka a "subdomain" namespace.   I
believe this would allow

  zeromq.readthedocs.io/libzmq

This nicely mirrors GitHub's .githup.io/ namespace for its
"pages" which naturally gives a spot from other zeromq repos to have
their docs on RTD.  Though some, at least PyZMQ, already have their own
subdomain on RTD.


The best I can tell from RTD's documentation is that their auth model
assumes a single individual "owns" the project or subdomain names in the
namespace.  I do not know how to best map this to libzmq's development
model.

But, (purely IMO) I think it is reasonable for you, Francesco, to "own"
the "zeromq" subdomain and "libzmq" project name on RTD.  After all, you
are the one actively doing the work.  If at some future time you wish to
transfer ownership you could of course seek someone to take it.  Even
letting things languish in the future seems okay to me as some future
interested person can follow the RTD procedure and take over the name
and the responsibility.

Re: [zeromq-dev] About libzmq "domain" inside readthedocs.io

[Francesco]

hi Brett, Arnaud,
Thanks for the fast answers.
I was not aware of the specific RTD procedure to claim an abandoned project.
I have submitted a ticket on their website to "reclaim" the libzmq project
and bind it to https://github.com/zeromq/libzmq .Unfortunately the form
does not provide any sort of ticket number after submission. I will post
updates I receive from RTD on this mailing list.

They mention a 6weeks period before a user can be declared as
"unreachable"...let's see...
In meanwhile perhaps some libzmq maintainer can simply register a new
project named "zeromq" and then later on we can setup some kind of
redirection rule

Thanks,
Francesco

Hi Francesco,

I think you should have no problem reclaiming the name "libzmq" on RTD.

I find this policy page:

  https://docs.readthedocs.io/en/stable/abandoned-projects.html

Scroll down for the info to provide and the link for how to request a

There is also a github user shanesquarestream

https://github.com/ShaneSquareStream

But it hasn't seen any activity for 10 years. It also seems to relate to 
'some' crypto company (ripple)

Re: [zeromq-dev] Cross compiling for STM32MPU - ARM

[Francesco]

Hi Venkat,

I suggest you read the page:
https://www.gnu.org/software/automake/manual/html_node/Cross_002dCompilation.html
which describes how to do a cross-compiler build of a project using
Automake in general (e.g. you're missing the --build option).
It seems that all the compiler errors you're having are not related at all
to libzmq.

My suggestion is for you as exercise/test to first cross-compile a simple
helloworld application that uses automake (you can follow automake
tutorials on the web to create such simple app).
Once you get that cross-compiled, you can try cross compiling libzmq

HTH,
Francesco

[zeromq-dev] About libzmq "domain" inside readthedocs.io

[Francesco]

Hi all,

I noticed that there is a user "shanesquarestream" that has registered the
project "libzmq" inside readthedocs.io:
   https://readthedocs.org/projects/libzmq/

The readthedocs.io website points to a fork of libzmq which has been
deleted since then: https://github.com/squarestreams/libzmq

Searching for that user "squarestreams" or  "shanesquarestream" inside
github provides no results.

Anybody knows such user/fork of libzmq?

I think it would be nice to get https://readthedocs.org/projects/libzmq/
registered against the official libzmq project, not to a dead fork...

Thanks!

Francesco


PS: we can still register "https://readthedocs.org/projects/zeromq; but I
think it might be confusing to have a dead page for libzmq...

Re: [zeromq-dev] Cross compiling for STM32MPU - ARM

[Edwin van den Oetelaar]

ChatGPT4 suggest using --with-sysroot and using the correct -I flags for
pointing to the correct include directories eg:

./configure --host=arm-linux-gnueabihf --with-sysroot=/path/to/arm/sysroot

This is not a specific issue with zeromq but skills about using the tools
of the trade.

Good luck,
Edwin
