What did you do?
While building couchbase master source code, I am getting the go-build issue for this particular module “cbq-engine”.

Error which I see:

If anyone has observed the issue before, please let me know. Any pointers would help.

I debugged more and found out that the parser/n1ql code wasn’t building fine.
Hence updated the source fresh using "git clone https://github.com/couchbase/query query"
and then ran the build.sh at “couchbase/goproj/src/github.com/couchbase/query/parser/n1ql” path individually. After this I was able to resolve the above build error.

However not sure why would the source at query wasn’t matching and where did this additional file came in from “y.tab.c”.

Thanks,
