Unknown/unsupported OpenSSL version ("30100040 (OpenSSL 3.1.4 24 Oct 2023)")

[ickc]

When installing on Arch Linux,

checking OpenSSL library version... configure: error: Unknown/unsupported OpenSSL version ("30100040 (OpenSSL 3.1.4 24 Oct 2023)")

From https://github.com/gridcf/gct/blob/07008c37abe56bafba82fe052b0f2cd11358ee88/gsi_openssh/source/configure.ac#L2844-L2862

Thanks for the pointer.

But I wonder why it doesn't work for your OpenSSL version 3.1.4. Because considering that https://github.com/openssh/openssh-portable/commit/f6d3ed9a8a9280cbb68d6a499850cfe810e92bd0 enables version 3.2.x and https://github.com/openssh/openssh-portable/commit/3e21d58a09894acb38dc69ed615d101131f473d0 enables 3.3.x, 301 should enable 3.1.x if I'm not mistaken.

And 301* should at least match the first part of 30100040 (OpenSSL 3.1.4 24 Oct 2023).

but the commit adds just the 300 and 301 as unsupported versions. Also the one before, from 2 years ago, adds 300 as unsupported version. That's different from this commit in the upstream patches.

No, I think there is no fall-through to the unsupported *) case. If there was, all cases would fall-through instead of ending at the ;;.

ah right indeed, sorry shouldn't have looked on my phone.

The problem is that the configure.ac in gct-6.2.1653033972/gsi_openssh/source is an old one. I just noticed that the configure and configure.ac in there only support up to 3.0.X. Also the current draft release still points to that version of Jun 8, 2022. The 301 support dates back to Feb 21 (see https://github.com/gridcf/gct/commit/f60262da4d171415c8482cdaeec4025a61ce8cab)

I made the same error at first, because it just looks like so.

Now I understand the problem. I didn't notice that issue as the OP quoted from current code state - where it looks and is OK IIUC - but used the last release tarball when trying to build the package on AUR, which is pre 2022-05-24.

Also the current draft release still points to that version of Jun 8, 2022. The 301 support dates back to Feb 21 (see f60262d)

Yes, I haven't yet updated the draft release since copying the content from the last release.

@ickc: This issue will hence be solved with the next GCT release that will materialize before end of this year.

[ickc]

Thanks all. I guess it should be closed now.

[fscheiner]

Oh, we usually keep issues open until there's a release that fixes them.

[ickc]

Ok, sure. Thanks again! Sorry for not having time to look into it again and providing more details, but you all figured it out already.
