[build help] pre-build package-check says packages aren't installed, but they are.

I’m trying to build some enso-os apps to use with opensuse’s xfce. Their tutorials are written with respect to ubuntu/debian, so I am not surprised that the pre-build check informs me that it cannot find packages that are definitely installed, I am just not sure what to do about it.

do I need to symbolically link something?
or use a find command to edit some specific files to look for the package in the right place?
Any guidance is appreciated.

First posts for building apps are usually posted to the Development forums, if they’re not OBS or Studio questions, are usually posted to the Programming/Scripting forum

Regarding your current issue,
Yes, it looks like the pre-check is checking for package names and not actual files… and package names without versions.
I’d guess that if the pre-check will allow you to proceed anyway without the pre-check succeeding, you can do so.

Then, you’d actually find out whether the build succeeds or fails.
Typically there is no risk to this, if the build fails, then you’ll never arrive at actually creating a final result, so you can literally attempt to build and fail over and over again, each time iteratively telling you what is failing step by step.
If you run into actual build failures because of a “file not found” or similar, then you can address however you see fit… perhaps creating a symlink.

Hi
With cmake files it should be looking for the development files/headers, suggest you install the respective development packages.

I did see the development forums, and ruled them out because they seemed super obs/studio related, but I will keep the linked Programming-Scripting area in mind for future use.

Development files. That should have dawned on me.

Thank you both!
