[timotheecour]

Example

echo "Hello World"

nim c --incremental:on --nimcache:/tmp/d05 -f main.nim # 1st one succeeds
nim c --incremental:on --nimcache:/tmp/d05 -f main.nim # 2nd fails

Current Output

Undefined symbols for architecture x86_64:
_main

Expected Output

should work

Additional Information

  latest devel 8117a94

@timotheecour works now, close? #17311 enables the hello world IC test but it already works in devel.

[timotheecour]

there should be a test before this can be closed

This works now.
