Your work-around is to compile with -DSQLITE_DISABLE_INTRINSIC.

[sqlite] sqlite3 3.17.0 fails to compile under OS X <= 10.10: use of unknown builtin

[Marius Schamschula]

Hi all,

I’m the maintainer of sqlite3 for MacPorts. When I updated sqlite3 to version 
3.17.0 on a machine running Sierra (10.12.3), everything went well. However, 
the next morning I woke up to the following ticket:

https://trac.macports.org/ticket/53568 

Upon further investigation, I found that sqlite3.c uses various workarounds, 
depending on the compiler version. Macs have defaulted to Apple’s clang since 
10.6. However, Apple’s clang versions are not the same as LLVM’s.

What happens is that CLANG_VERSION is set incorrectly, and sqlite3.c fails to 
compile under OS X 10.10 and all versions using clang below. The fact that the 
latest version of Xcode (8.2.1 available for macOS 10.11 and 10.12) built 
sqlite3 3.17.0 correctly is just dumb luck. This build failure is a serious 
issue for MacPorts as it is a blocker for numerous other ports depend on 
sqlite3.

No surprisingly, my very old Leopard machine (10.5, using gcc-4.2) cleanly 
build sqlite 3.17.0.
