Required dependencies not installed along with juce-tools

[Ankush Menat]

I installed projucer using `juce-tools` package and tried to compile a basic audio project without any modification. It fails as some required libraries are missing.

I found solution on JUCE forums. https://forum.juce.com/t/list-of-juce-dependencies-under-linux/15121/44

It suggest following packages as dependencies, after installing them compilation went smoothly.

libasound2-dev
libcurl4-openssl-dev
libx11-dev
libxinerama-dev
libxext-dev
libfreetype6-dev
libwebkit2gtk-4.0-dev
libglu1-mesa-dev

I believe these packages should be considered as dependencies to prevent same problem from occurring for future users.

To reproduce you need to start with basic installation and install `juce-tools` package. After that you need to start an "Audio project", it will create Makefiles. Run make and compilation will likely fail because of missing dependencies.
I can provide any additional information required.

This seems to be a misunderstanding of the package relationships in Ubuntu/Debian.
see e.g. https://www.debian.org/doc/debian-policy/ch-relationships.html

Quote:
Depends
This declares an absolute dependency. A package will not be configured unless all of the packages listed in its Depends field have been correctly configured (unless there is a circular dependency as described above).

Recommends
This declares a strong, but not absolute, dependency.
The Recommends field should list packages that would be found together with this one in all but unusual installations.
End of quote

As far as I understood, juce-tools can be installed without all those extra packages that are listed on that forum psoting, and you can start projucer without these. So they do not qualify for a "depends".

If your attempt to compile an audio project fails with missing dependencies, then this is something different and in my opinion falls into the "recommends" category.

Isn't this enough?
