SDL2_image not found by pkgconf

I'm using SDL2 and SDL2_image for learning the C lang, and after some search about cmake(not easy to use with SDL2) I've set up a meson/ninja build system. Meson use pkgconf to found dependencies.

I've installed sdl2_image from the extra repo, but it doesn't provide the pkgconf necessary files to found the «package»

And because of that I get an error when I'm building my project, I've fixed the problem by using the subproject functionality of meson.
But it's weird that I've the files on my system but I need to re-download them in my project.

Sorry if this is not in the right place.

Re: SDL2_image not found by pkgconf

The pkgconf file is there: /usr/lib/pkgconfig/SDL2_image.pc what exactly is your pkgconf line?

Not a pacman issue, moving to programming and scripting

Re: SDL2_image not found by pkgconf

pkg-config names are case sensitive, abd sdl2 uses both sdl2 and SDL2 for different packages...

pkg-config --libs sdl2 SDL2_image

You can list the installed libraries like this:

pkg-config --list-all | sort | less

Oh, that's why it's not found.

pkg-config --list-all | sort | less

I was searching for sdl, and not SDL

SDL2_gfx                       SDL2_gfx - drawing and graphical effects extension for SDL
SDL2_image                     SDL2_image - image loading library for Simple DirectMedia Layer
SDL2_mixer                     SDL2_mixer - mixer library for Simple DirectMedia Layer

Thanks, it's working now.

But why is SDL2_image not equal to sdl2_image ?

Because *nix is case sensitive.

Yes of course.

But then why sdl2 and SDL2_image and not SDL2 ant SDL2_image.
Why one is in lowercase and the second is mixed ?
