Hi all,
I've been updating scripts for building gnustep-base for Android. Sadly, I'm having issues with building libobjc2.
It's failing on arc.m and looks like a possible bug in clang. I have no idea how to dig deeper. Other files up to this one seem to be building fine.
David, any thoughts?
I'm using it on non-pristine Ubuntu 14.04.
clang3.4 comes with Android NDK r9d.
The command line below has been taken from "make VERBOSE=y", as generated by cmake.
