Arch - MGCB.exe exited with code: 255 (System.DllNotFoundException: freetype6.dll)

I’ve recently installed Arch and am trying to compile my MonoGame project for it. Everything worked fine on Debian, so I am unsure what I am missing here. Here is the build output I get:

I’ve installed the freetype2 package using pacman, which should contain libfreetype6, so I am totally lost as to what’s going on here. The standalone pipeline works fine, but not being able to debug in MonoDevelop is a pain.

EDIT: I just added SharpFont.dll.config with the following contents to the NuGet package folder for MonoGame.Content.Builder.3.7.0.9 (grabbed from MonoGame.Dependencies repo):

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <dllmap dll="freetype6.dll">
        <dllentry os="linux" dll="libfreetype.so.6" />
        <dllentry os="osx" dll="libfreetype.6.dylib" />
    </dllmap>
</configuration>

Now I get a different error:

This looks very similar to an issue that was on OS X. Does anyone know the solution?

I ran into this on my laptop on windows and had to instal the optional dll’s for the c++ runtime sdks.

Yeah, this is Linux, that’s not applicable.
