:frowning: The odd thing is that I do not get these while OpenSSL 3 is used on various platforms. The main question though is what replaces these interfaces and is there a volunteer to make the necessary changes?

3

The OpenSSL 3 migration guide may contain some relevant info.

I’m not very familiar with the OpenSSL interface and the differences introduced in version 3, but I can give it a shot if there are no other takers

That would be great, I don’t have much time now. :slight_smile:

Looking into it :slight_smile: Strangely I couldn’t reproduce these warnings yet on a Debian machine with a fresh OpenSSL built from source, even after explicitly adding -Wdeprecated-declarations to CFLAGS…
I’ll update to a newer gcc (so far I tried with version 10.2) and see if it surfaces the warnings then.

Interesting. This is the file archlinux uses to build openssl: svntogit-packages/PKGBUILD at packages/openssl · archlinux/svntogit-packages · GitHub . Doesn’t look like it has anything special to enable the deprecation messages. So it must be the gcc version. I am using:

gcc version 12.2.0 (GCC)

@swi I was (finally) able to reproduce the deprecation warnings and I think I understand the situation a bit better now. The thing is that SWI-Prolog already prefers the non-deprecated EVP interface and the calls to the deprecated functions (the ones causing these warnings) seem to be correctly guarded by #ifdefs.

So to get the warnings I needed to unset USE_EVP_API explicitly. USE_EVP_API is defined whenever a set of functions are found during configuration, so now I’m wondering if one of these functions is missing from the Arch Linux OpenSSL distribution, and if so which one…

@oskardrums thanks for figuring this out! I looked around to see why this could happen. At first I thought that it was caused by the fact that I have two openssl versions installed, 1.0 (I need it for some old binaries) and 3.0. So the first step I did was to remove openssl-1.0 and see what would happen. The warnings still showed up.

Next I thought, that if it depends on cmake finding some functions maybe it was keeping some stale settings in CMakeCache.txt, so I removed the cmake cache and voila! The warnings are gone.

Thanks for tracking this down!

EDIT: I am glad it was as easy as that.
