Sorry, crossed with your comment.

Yes, your latest patch eliminates the build warning for me.

Looking at my trial patch, I could eliminate that warning but it needed a line like `curl_easy_setopt (easy, CURLOPT_MIMEPOST, mime);` where `easy` was defined by `CURL *easy = curl_easy_init ()`. Not sure if that was needed.

Oops, I missed one renaming.  Try pulling and building again with cset 17ec50a2f044.

I'm still getting a gcc warning

but I'm more confused by the fact that the structure pointer "mime" is never changed to something other than nullptr before it is used. Where is mime assigned to a valid mime struct?

It turns out the recoding away from curl_formadd() was rather tricky.  I made the changes in this changeset: http://hg.savannah.gnu.org/hgweb/octave/rev/22b12276375e.

I don't have a version of gcc that produces any warnings so I'm marking this as Ready for Test by someone who does.

I am attaching a trial patch for this bug. It builds and passes "make check" but I have no idea if this is the right way to do it. It needed a lot of changes with the new curl API. Pls review.

Resources used to make this patch:

Changing the constants was OK but changing the function names requires more thought to ensure the wrapping is correct.

WIP patch that removes two of the warnings:

@Arun: I think you can go ahead and upgrade to the new names for Curl constants.

The curl release history is available at https://curl.se/docs/releases.html.

Curl 7.55.0 was released in Aug. 19th, 2017 and is 5 years old so changing to CURLINFO_CONTENT_LENGTH_DOWNLOAD_T seem reasonable.

Curl 7.56.0 was released in Oct. 4th, 2017 and is also 5 years old.

I think it is fine to change this, but not on the stable branch right now before the 8.1 release.  I would do it on the development branch.

After a recent system update to the curl utility and libcurl libraries, there are build warnings about calling the curl library in a deprecated manner. It does not break any functionality yet.

hg id 96d321d59ee3 (stable)

Compilers: gcc, g++, gfortran 12.2.0

Curl version 7.87.0
