Complete build log

[Sergey Kandaurov]

As per the build output, this is a problem in the 3rd party module ngx_http_headers_more, apparently after ef6a3a99a81a.
For problems with 3rd party modules please contact module authors instead.

[Maxim Dounin]

For the record, there are multiple header-releated changes in nginx 1.23.0 internal API, see ​CHANGES:

    *) Change in internal API: now header lines are represented as linked
       lists.

This includes the explicitly mentioned change to use linked lists instead of arrays, as well as various renames to match the new approach to headers. For the details about the particular change causing the build failure, see ef6a3a99a81a. The 3rd party modules you are using need to be adjust to work with nginx 1.23.0.

Note that this also applies to the auth pam module, though likely it will build without errors. This is because it adds the "WWW-Authenticate" header, and this now needs header's next pointer to be set to NULL, see d26db4f82d7d and 711737177b77.

Then why does it compile without errors on debian bookworm?

[Alexander Kubyshkin]

Replying to actionmystique@…:

Then why does it compile without errors on debian bookworm?

That's because of authors of ngx_http_headers_more_filter_module adjusted the module to compile with 1.23.X. Not related to debian version.
