How to make Antrl in Unity cross-platform?

Question

C++ / C#

Actually, I used Ncalc for some of my tasks on a third-party project, but the trouble is, when transferred to a dumb one, this thing will not be cross-platform

Answer 1

1. So Antlr or NCalc?
2. NCalc cross-platform and so. Use the version under .netstandard
Although on iOS and other platforms with il2cpp will not work, yes.
