Hi Antonio, Simulating ARM & x86 at the same time won’t work today. If you wanted to make it work, you’d need to teach the build system how to generate compile all the architectures into a single binary, and fix some places in the code where we use #defines based on the architecture to dynamically determine the architecture and take the appropriate action. If you end up going down this path, let us know, I’m sure some other people on the mailing lists could have suggestions.
