Subproject 'shared-mime-info' did not override 'shared-mime-info' dependency and no variable name specified

I am trying to cross-build openslide for linux, and gdk-pixbuf requires shared-mime-info. When I add it as a dependency for my meson project (rather than just implicitly via gdk-pixbuf) and include a wrap file as follows:

[wrap-file]
directory = shared-mime-info-2.2
source_url = https://gitlab.freedesktop.org/xdg/shared-mime-info/-/archive/2.2/shared-mime-info-2.2.tar.gz
source_filename = shared-mime-info-2.2.tar.gz
source_hash = bcf5d552318136cf7b3ae259975f414fbcdc9ebce000c87cf1f0901ff14e619f

[provide]
dependency_names = shared-mime-info

I get the error from the title. I have seen this discussion, but it doesn't seem applicable here.

How can I tell my wrap file to override the dependency?

[eli-schwartz]

That discussion is applicable here (although there are extra nuances for shared-mime-info). There are two ways to specify a dependency in a wrap file:

• using dependency_names which requires that the subproject collaborate by using the meson.override_dependency() method in its meson.build files
• using shared-mime-info = shared_mime_info_dep where the left hand side is the name of the dependency, and the right hand side is a meson variable that was assigned like this: shared_mime_info_dep = declare_dependency(...)

[alanocallaghan]

So if the project uses neither override_dependency nor declare_dependency, I'm out of luck?

You can submit a pull request to the project, or you can create a *.patch file, then use it with diff_files as described here: https://mesonbuild.com/Wrap-dependency-system-manual.html#diff-files

Warning: requires additional build dependencies, patch or git apply may not be installed on all build machines. Also, it requires relatively recent versions of meson itself.

Thanks! Sorry if it's a simple question, I've been doing my best to get through the docs but am jumping around a bit as I encounter issues. Very much appreciate your work and the speed of answering this is phenomal

Cheers

No problem, that's what we're here for. :)

(After all, this is the discussion and Q&A section, not the bug reports section. :D)

Also this (diff_files) is relatively new so there's less hive mind knowledge about it.
