slint Misleading compilation error when default font cannot be embedded when embedding glyphs

Misleading compilation error when default font cannot be embedded when embedding glyphs

When building with slint_build::EmbedResourcesKind::EmbedForSoftwareRenderer, we get misleading compilation error when the default font don't exist.

To reproduce, edit the carousel_demo.slint and change the default font binding:

default-font-family: "NOT EXIST";

Then you get the error:

error: could not find font that provides specified family, falling back to Sans-Serif
    --> /home/olivier/slint/examples/carousel/ui/carousel_demo.slint:22:26
     |
  22 |     default-font-family: "NOT EXIST";
     |

It says it is falling back, but it doesn't since it errors out.

The error is even worse if the invalid font comes from the style. Eg, modify the material-base/std-widget-impl.slint to change the default font

    out property <string> default-font-family: "NOT EXIST";

and remove the default-font-family property from the window. Now we get:

error: internal error: fontdb could not determine a default font for sans-serif
   --> /home/olivier/slint/examples/carousel/ui/carousel_demo.slint:8:38

  8 | export component MainWindow inherits Window {
    |                                      ^

I am also having a similar issue on FreeBSD... Anyone have a fix yet? I used the default template with cargo-generate. It seemed to build fine, but when I ran cargo run I got the error you see below.
