Microsoft (R) C/C++ Optimizing Compiler Version 19.40.33813 for x64

Nim 2.2.2

nim.cfg:

cc = vcc

demo.nim

import nimscripter
proc doThing(): int = 42
exportTo(myImpl, doThing)
const 
  scriptProcs = implNimScriptModule(myImpl)
  ourScript = NimScriptFile("assert doThing() == 42")
let intr = loadScript(ourScript, scriptProcs)

Nothing in the output is remotely helpful, I do see vmgen.nim which makes me think it's not nimscripter but Nim itself that is not vcc compliant. Can you try compiling Nim with vcc and report back, I don't have a Windows machine?

[ingoogni]

Sorry, i have no idea how to do that. I tried ./koch boot --cc:vcc and that failed. The linker could not find a file in icon dir.

VCC is not overly supported by Nim so don't know what to say then.

[ingoogni]

I understand. Let's leave it at that then. Or, should I report it Nim's git?
