Linux dependencies

[whitebyte]

I'm following https://github.com/buggins/dlangui/wiki/Getting-Started and the hello world app fails to build if zlib isn't installed. It started working after apt install zlib1g-dev (Ubuntu). Is it an actual Dlang dependency or a transitive dependency from its packages?

Also, freetype mentioned here #665 probably also should be listed as a dependency (libfreetype-dev on Ubuntu)

Hi! Actually, there's std.zlib and that's where the dependency probably comes from. Have you checked if anything that uses std.zlib compiles? eg

import std.zlib;

void main()
{
    compress("whatever");
}

As per freetype, as far as I understand, dlangui depends on bindbc-freetype and it should bring in the library when you dub. I main Windows 11, so I don't build on Linux often, and my Manjaro KDE laptop never had issues building any of dlangui projects.

If you can confirm that it's not the case -- feel free to add that to instructions :)

It did not. The app started compiling only after I installed it through OS package manager.

It compiles and runs without issues. But again, I installed it via apt It works even with zlib1g-dev removed

Thank you for your report! I'll try investigating this once I get a chance to work on Ubuntu

Hi.

I had a similar problem.
It happened when I had only libfreetype6 installed on Debian:

sudo apt-get install libfreetype6

This is the solution that worked for me:

sudo apt-get install libfreetype6 libfreetype6-dev
