Doesn't build because compilation errors
Closed this issue · 1 comments
Trying to build on Ubuntu 18.04 64bits I'm getting the output shown bellow (have you forgot to commit/push something ?):
./build

It's not finished right now. Two days ago I came up with the language that describes the tokenizers. Right now I'm writing the parser for that language. After that I'll have to come up with the language for parsers and implement that too. Then comes symtab and code generation. Give it another month or two, and I should have something usable. That's the hope, anyway. Depends on how much time I have.
I don't know what your needs are. In the meantime though, if you're looking for a parser-generator that actually works, I would recommend packcc or antlr. I'm updating the readme with how pgen (will) differ from those options.
