+[DLib](http://dlib.net/) is a modern, C++-based toolkit which provides several machine learning algorithms.
+
+## Compiling without AVX support {#compiling-without-avx-support}
+
+Especially older CPUs don\'t support [AVX](https://en.wikipedia.org/wiki/Advanced_Vector_Extensions) (Advanced Vector Extensions) instructions that are used by DLib to optimize their algorithms.
+
+On the affected hardware errors like `Illegal instruction` will occur. In those cases AVX support needs to be disabled:
+
+```nix
+self: super: { dlib = super.dlib.override { avxSupport = false; }; }
