As I've said below, the current build will build a simulator which include the 'capabilities' that your build environment has available.

Just because you've built a simulator which is network capable, doesn't mean that you will be forced to run your simulator with network devices enabled or with network devices connected to any particular network.

If you don't want your simulator to run with a network connection, then don't enabled the network device and don't attempt to connect it.

Hi Bill,

Anything is possible, however, what is the real goal behind your question?

If your build environment doesn't have the necessary components to support network activities, then you can't build binaries with network support.  The makefile looks around for components which are available on the build system and the binaries are built which will work on that system.  Even if libpcap is available on the build system, the binaries dynamically load libpcap at runtime so binaries built on a system with the necessary pieces will actually run on a different host of the same platform type and provide libpcap networking support if the executing system has libpcap available and not if it isn't available.

Please explain what you are trying to achieve.

Thanks.

    Is it possible anymore to compile the emulators without networking support naymore. Or is that choice gone. I noticed at compile time there's a lot of dynamic libraries here being linked in at compile time.
