Hi,

 From the look of that PNG, you're building in a native Windows
environment.  The ony configs available in the main source are for
Visual C, and are configured like this:

If you meant to cross compile for a Linux, I do not have an answer for
you.  In that case, it would probably be better if you could build
directly on the intended box.


good catch - but that is an issue that is hard to overcome with the (almost obsolete) Xeon Phi COprocessors. Normally you'd build a cross-compile for the Phi on the host system using the Intel C/C++ compiler, by adding a flag "-mmic" (or /mmic) to the CFLAGS variable. On Linux, this is easy to do - I have built several versions of OpenSSL for the KNC Xeon Phi. For Windows, however, you are stuck between an OpenSSL environment which only supports VC and an Intel/Xeon Phi environment which insists that you use ICC with the flag "-mmic" .

The question asked by the original poster is better answered on the Intel MIC developer forum.

cheers,
