Re: [Tack-devel] Questions about LLgen

[Wild Pi <wi...@pr...>]

Thank you for fixing the build error. Although make still fails with the error below, LLgen is built successfully. I'm going to play with it.

Going back to my second question. Have you built any OO language (C++/Java etc.) parser with LLgen? Basically, I'd like to know how practical it is to build a high quality parser for a full feature OO language. It'll be very helpful if someone could share their experience.
