Please make sure to do a clean build: execute ./clean.sh first and then ./configure ; make (or alternatively ./build.sh which uses a different set of makefiles)

I've seen this problem when there are still some old object files lingering about.

[genivia-inc]

The HW and CPU detection related variables and functions were moved from input.cpp to simd.cpp where this belongs.

[genivia-inc]

Ah, I see you're using cmake. The CMakeLists.txt should be updated to include simd.cpp:

set(lib_sources
  lib/convert.cpp
  lib/debug.cpp
  lib/error.cpp
  lib/input.cpp
  lib/matcher.cpp
  lib/pattern.cpp
  lib/posix.cpp
  lib/simd.cpp   <-- add

Thanks for the quick turnaround. I could have noticed it :)
