[Tack-devel] Questions about LLgen

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

Hi, there,

I'm new to LLgen and compiler in general. I just downloaded ACK, but I'm only interested in LLgen at this point. I'm trying to build and use it. I'm using GCC 7.5.0 on Ubuntu 18.0.4.

When I run ./pm from LLgen/ directory, it failed with some errors. I played with the ./pm script, and produced the .pm-exec-x86_64 binary. But it exited with this error:

./pm

pm: cannot read pmfile: No such file or directory

My first question: how can I build LLgen on 64-bit Ubuntu?

My second question is about LLgen. I'm thinking to build a parser for a C++/Java like language. I notice clang is a hand written recursive descent parser. So I guess LLgen can be
used to build a parser for a similar language. But before I spent tons of time into the project, could someone with LLgen experience tell me if LLgen can be used to implement, say,
a full featured C++ or Java parser?

Thank you,
