A new update to glib-2.0 removed gurifuncs.h from /usr/include/glib-2.0/glib/ I think it’s called guri.h now. The problem is I need this .h to build JUCE6 framework applications. Is there a way to install an older version that still contains this file alongside the new version without breaking stuff.
It’s been a while since I did software development, but a .h file just defines things so try copying just the .h and .c file where it’s supposed to be and see if that works.
If it doesn’t:
- delete the files
- I’m all out of bright ideas, sorry.

Isn’t there a way to install an older version of glib and tell gcc to use this then switch it back when I’m done working? I thought about just copying the file, but I’m hesitant because it says ```
#error “Only <glib.h> can be included directly.”
Never mind I ran make clean and it correctly used the newer version of glib. Happy Days 
Thanks for your time

I’ve marked the below answer as the solution to your question as it is by far the best answer you’ll get.
However, if you disagree with my choice, please feel free to take any other answer as the solution to your question or even remove the solution altogether: You are in control! (I just want to avoid even more subjective opinions being posted and confusing you even more)
P.S. In the future, please mark a solution like this:
so that the next person that has the exact same problem you just had will benefit from your post as well as your question will now be in the “solved” status.
