[Barrelfish-users] yacc error

[Georgios Varisteas]

Hi Gerd,

My yacc version is 1.9.1-r4 (last stable in Gentoo Linux)

$ hg summary 
parent: 923:30ad14bd713a tip
 adding a tag for release 2012-06-06
branch: default
commit: 2 modified, 5 unknown
update: (current)

The modified and unknown files in the summary are what's generated by "making" the parser.

I tried this on a clean clone and had the same problem; the compiled parser is not in the repo as far as I can tell. After manually building the parser everything compiled normally. 

cheers,
Georgios

Hi georgios,

Ideally you should not have to build the parser yourself as the generated code already exists. The parse.y file and the makefile is only there in case you want to modify the functionality of the current parser. However, it is weird that hake is trying to build the parser all by itself. May I ask which revision you are using and which version of yacc you have installed so I can do some tests?
