fortran-curl's Issues
Runtime problem when using Apple Silicon
Came to http-client (another project) from: https://twitter.com/kelseyhightower/status/1696196971277775348
Installed fpm with brew from homebrew-fortran.

Then noticing that the http-client example code gives a runtime failure:
Error message:URL using bad/illegal format or missing URL
Figured that internally it uses this project, fortran-curl.
Maybe you have a clue where to look, since everything compiles just fine. Not sure if Apple Silicon is even the thing causing the bug.

Though above it says x86_64, it's actually ARM64.

Apart from the http example outputting some garbage (probably an uninitialised string) under the 0.1.0 and 0.1.1 tag, all of the earlier versions fail in a fairly similar way. So it's not an introduced bug (not a regression).
Errro while building the project
During the execution of fpm build, it appears that the library is not being built correctly. The following error is encountered:
build/dependencies/fortran-curl/src/curl.f90:1135:57:

Version number?
I haven't found a version for this project yet. While the important version number might be the libcurl version, the version of the Fortran interface is relevant for consumers of this library as well.
Is there a plan to add a version number and/or create versioned releases for this project?
Retrieve Response Cookies
Hello @interkosmos,
How can I receive response cookies in an HTTP request? I know that one way to do this is to search for cookies in the response headers, specifically in the Set-Cookie header.
I have found that in curl, we can use the curl_easy_getinfo function with the CURLINFO_COOKIELIST option to retrieve cookie information. However, I am encountering an error while using this approach. Can you please provide an example demonstrating how to receive cookies using the CURLINFO_COOKIELIST option? Alternatively, if you know of any better approach, please let me know.
Missing implementation of libcurl MIME interfaces in fortran-curl
Hi @interkosmos ,I noticed that the fortran-curl library does not currently implement the ISO C binding interfaces for libcurl's MIME feature. This means that users of fortran-curl are unable to send multipart form data.
Could you please consider adding support for these interfaces so that users can take advantage of this important feature? It would be great to have this functionality available in future releases of fortran-curl.
Thank you for your attention to this matter.
