X86_64 crash

Hello

With Xcode I can't get Embree to work in 64 bits (wth/without ispc). Basic = operations use avx commands that my machine has not. Crash screenshots are attached. In 32bits all is fine. Embree 2.3.3, Xcode 4.6.2. icc 13.0, OSX 10.7.

Any idea?

Hi,

Embree uses a cmake-based build infrastructure which takes care that only special code paths are build with AVX/AVX2/.. instructions, and all "surrounding" code uses only simple SSE instructions. The special AVX/AVX2 code paths are only executed at run-time when your machine supports the specific ISA extensions. Embree does not support the Xcode build environment directly so I guess you would have to somehow emulate the cmake infrastructure/rules within Xcode.

Carsten.
