Compiled code can conclude the instruction set through conditional compilation. But what about processor-independent scripts? Finding out the current native processor architecture and emulation status thereof would be very useful in build systems that doesn’t support cross-compilations. Find out how a shell script can find out whether it is running under Apple’s processor, Intel, or emulated.
Being in the “bleeding edge” has its drawbacks in addition to benefits. Blazing a fresh trail means it’s more rough and plenty of unknowns. Similarly in open source software, support for the ARM architecture is slim and even slimmer on the Mac. But there is a way to run “legacy” Intel-only command line apps on the Mac.
The long-rumored ARM Mac is on the horizon. With this comes the big work of porting and re-compiling current applications. But many Mac App Store apps are dependent on OpenSSL, which doesn’t yet support ARM on the Mac. Here is how you can continue to test your mac app while waiting for official OpenSSL support for the new hardware.
Debugging on Android can be a pain at times – some of these can be attributed to the architecture of its developer tools. If you find the emulator’s startup time to be too slow for you, there may be a configuration option that you’ve overlooked and can make the emulator a lot fster.
