Compiler errors in FlashDevelop which don't appear in Flash Builder?

Question

I'm trying to build a project with FlashDevelop, which I was able to build using Flash Builder without any special settings.

FlashDevelop shows errors:

"Ambiguous reference to..."

"A conflict exists with inherited definition..."

and doesn't compile.

I looked in compile settings but didn't find a way to disable this.

Don't advice me to fix the errors, I just want to know why it works in Flash Builder and not in FlashDevelop.

Answer 1

I was using a different Flex SDK (removed version name from the directory, and assumed it was the same...).
