[Krom | Windows] Shader compiler error while exporting skinned meshes

[knowledgenude]

While trying to export an .exe for the open jam, i faced this error.

The error doesn't happens while exporting for Linux (Krom).

Info: Publishing project, check console for details.

Are you trying to export from Windows or Linux?

If it's the latter, I think this issue may be because https://github.com/Kode/krafix might not support cross-compiling from linux for directx, though I'm not sure

Update

RobDangerous confirmed it that isn't possible to cross-compile from linux to directx bytecode because of libraries not available.

As a side note, maybe a check could be added to the exporter to detect this and halt the process with a pretty message instead of that error :sweat_smile:

@N8n5h , thanks for the answer! Do you think that would be possible to export to DirectX trough WineHQ? In my test another error appeared:

Also i've tried to export to OpenGL from Linux and after the project is successfully exported, an exception is throw and the folder with .exe is not generated at all:

By briefly investigating this popped up: https://github.com/samhocevar/d3d4linux, so it seems doable that way if done in a similar fashion.

Also i've tried to export to OpenGL from Linux and after the project is successfully exported, an exception is throw and the folder with .exe is not generated at all

The issue occurs because there is no opengl krom binary by default included in the sdk, just for directX https://github.com/armory3d/kromx_bin. Maybe compiling https://github.com/armory3d/armorcore with -g opengl on Windows could work, but haven't tested it...

I've configured a workflow to build a opengl windows executeable in armorcore which stores the binary for download: https://github.com/tong/armorcore/actions/runs/3743141811

Any windows users who can confirm it works?

Note: Since only users with write permissions to the repository can access artifacts you have to add the workflow config to your fork of armory3d/armorcore and build the binary in your own repo/workflow (by checking out my branch).

I got a report that the exe is working.

Works for me as well (I could download the artifact btw, without write permissions I guess).
