Looks like there is a mismatch between your bionic headers and your kernel headers. Probably the bionic headers were not updated to match the kernel headers.
You could start off by checking the SHA ID of the heads of the buildable and non-buildable code. Ex [cd XX; git rev-parse HEAD;] Check if the working code has some other commits that you need using git log, if so you can checkout that commit, or patch it in any other way. Try to check for some changes in the include paths, if any too.
