Build fails on missing libcurl4 dependency, even though it is installed

[johnlb]

Describe the bug

Firstly: running Ubuntu 24.04 on wsl2.

So, I'm building DT from source for the first time and I can't seem to resolve a dependency issue with libcurl4. It seems the libcurl4 package was renamed to libcurl4t64 in Ubuntu, but they are not properly linked for some reason so cmake doesn't know it is there. I think there is a fix for this in the curl codebase (https://www.mail-archive.com/debian-bugs-rc@lists.debian.org/msg674605.html), but it is on a newer release than exists in Ubuntu's repos (I have 8.5.0, the release was 8.6.0, latest is 8.8.0), so I haven't been able to test it.

Is it possible there is a workaround along the lines of adding libcurl4t64 as an alternate for libcurl4 in the dependencies?

Here is the shell output when building:

error: missing dependencies for building c-darktable

Here is the shell when I try to install libcurl4:

$ sudo apt install libcurl4

Note, selecting 'libcurl4t64' instead of 'libcurl4'
libcurl4t64 is already the newest version (8.5.0-2ubuntu10.1).
The following packages were automatically installed and are no longer required:

Steps to reproduce

1. sudo apt install curl
2. scbi --deps --update c-darktable

Expected behavior

DT should build correctly

$ sudo apt install libcurl4

You should use libcurl4t64 indeed. Please make sure you use recent scbi version (not sure it will solve the issue though).

Note that I don't have issues building on Debian/sid.

You can try scbi's option: --deps:warning to make this check not fatal.

Is it possible there is a workaround along the lines of adding libcurl4t64 as an alternate for libcurl4 in the dependencies?

That's the case in recent scbi plug-in. Make sure you update.

I'm working from the getting started page (https://github.com/darktable-org/darktable/wiki/Getting-started) and it has me building scbi from source, which should be the latest, yeah? I had only built it within an hour or so of seeing this issue. Is there a different version I should be using?

scbi --version gives:

SCBI : v9.8-5-gc8cf619
CORE plugins : v9.6-5-gefd815a

[TurboGit]

No, sounds good. This is the latest version.

[TurboGit]

I see that you are on wsl... I'm wondering if this is not the issue ! What is the output for:

$ uname -a

and:

$ lsb_release -d

[johnlb]

Yeah certainly possible. I was hoping not since I'm on the latest everything.

$ uname -a
Linux LAPTOP-JC264AT5 5.15.153.1-microsoft-standard-WSL2 #1 SMP Fri Mar 29 23:14:13 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

$ lsb_release -d
No LSB modules are available.
Description: Ubuntu 24.04 LTS

[johnlb]

I'm not sure what to check for if that is the case. I've been using the latest DT build for a week or so now, and that's been fine (was using win before), though that shouldn't matter as much for the build process. Here's the version of cmake I've got:

$ cmake --version
cmake version 3.28.3

CMake suite maintained and supported by Kitware (kitware.com/cmake).

[TurboGit]

Hum, all this seems good, so what the output for:

$ scbi --stat:short

And

$ which scbi

[TurboGit]

There is something fishy that I don't understand yet, I do use scbi exclusively to work on darktable (and many other projects).

[TurboGit]

Ok, I think I found the issue, the Ubuntu package alias was not properly updated (it was on Debian). So please update to latest scbi version.

[johnlb]

That works! Seems to be building correctly now. Thanks so much!

[TurboGit]

Good to hear, closing then.
