Build error in offapi module

[LOH KOK HOE]

I was trying to make a clean build using this command ./autogen.sh and have
encountering a build error in offapi module. I am running out of clue on
how this problem could be solve. Below are the details of the stack trace,
hope you guys can give some pointer.
