File for icon not found by lfc

[edwardalee]

The lfc command fails to find an icon file in the same directory as the .lf file.
And example is given here: https://github.com/lf-lang/examples-lingua-franca/blob/main/C/src/rosace/Rosace.lf
That file has this:

@icon("Variables.png")
reactor Variables {}

which displays fine Epoch:

However, when I run lfc on the file, I get a warning:

> lfc src/rosace/Rosace.lf 
...
lfc: warning: Icon does not exist.
 --> src/rosace/Rosace.lf:68:7
   |
67 | // Documentation
68 | @icon("Variables.png")
   |       ^^^^^^^^^^^^^^^ Icon does not exist.
   |
69 | reactor Variables {}

@a-sr, I vaguely recall that we had disabled this functionality, but I don't recall why. Could we bring it back?

Klighd is currently missing the necessary support for images in VSCode (kieler/KLighD#146), see also #1473

Maybe the warning should be adjusted to state that instead of "Icon does not exist" then?

Sorry, I did not get the context of the question right. Yes, displaying icons is currently disabled but it will not raise this warning, it just won't display the icon. The warning here in fact means that the code cannot locate the icon file. My guess is that the code is not ready to run in LS mode because I never tested it there given the fact that the icon won't show up in the current state.
I can take a further look into this issue.
