While coding a Raspberry Pi application I do use my PC most of the time since it is a little faster then the Pi.

Today I got the following message when a WiringPi specific code (wiringPiSetup();) got called:

piBoardRev: Unable to determine board revision from /proc/cpuinfo
 -> No hardware line
 ->  You may want to check:
 ->  http://www.raspberrypi.org/phpBB3/viewtopic.php?p=184410#p184410

I would like to skip Raspberry Pi specific code (such this WiringPi part) but execute the rest when running on a PC.

Actually how should I approach this issue?

    At this point, you're the only one who's seen your code, so you're the only one who can know what parts to cut. In general, you'll need to *mock* the parts that you can't run on your PC. – Jonathon Reinhart Jun 03 '16 at 01:10
  • Should I run Pi specific code in run time like a plugin? – KcFnMi Jun 03 '16 at 01:15

    No, just write your own replacement library that mocks the functionality of the library you're replacing. – Jonathon Reinhart Jun 03 '16 at 01:39
  • I never touched the mocking area. Would you mind to give an introductory suggestion about which tools to use (portability across Linux/Windows is appreciated)? – KcFnMi Jun 03 '16 at 09:49

My first solution would be to so include the pi specific code in something like

#ifdef __arm__
  /* pi specific stiff */
#endif

I don't have a PI at hand right now, so I'm not absolutely sure if the macro __arm__ is correct, but gcc and g++ should work, see sourceforge article on architecture defines.

This is a lot easier than mocking everything, but on the other hand the code is not even compiled on your PC, so not even compiler errors would show up here.

  • *"the code is not even compiled on your PC"* is kind of a risky assumption ... there are cross-compilers, you know ... in fact there are whole bundles of cross-compiler **and** emulators out there, its very possible to write, compile and run code for another platform on your PC, thats what i did for a living a few years ago – specializt Jun 03 '16 at 11:28
