for December 2011
We are pleased to announce that Red/System v0.2.3 is out, extending Red to the mobile world with a complete support for Linux on ARMv5+ processors. The new port supports 100% of Red/System features and passes successfully the 8537 unit tests.
For those of you interested in more details, our ARM port targets the v5 family, with 32-bit instructions (no Thumb support) and optional literals pools (use -l or –literal-pool command-line option when compiling) that implement a global allocation strategy (unlike gcc’s function-local allocations).
New compilation targets have been provided for Linux and derivative OS running on ARM:
Android support is using the same code as Linux-ARM, only differing in libc and dynamic linker names.
Currently, as Red/System only works on command-line in Android, you need a special loader to download the executable and run it. This can be achieved using the NativeExe app. You will need to allow temporary installing apps from non market sources (Settings > Applications > Unknown sources). Also, your local 3G provider might be filtering out executables downloaded this way, you can workaround that by either manually loading the NativeExe-0.2.apk file with adb, or share a wired Internet connection with your mobile device.
You can easily install NativeExe app by just typing the following URL in your Android web browser:
or by scanning this QR-code instead:
Once done, input in the second field:
http://sidl.fr/red/hello and hit [Run].
Here are a few screenshots of HelloWorld tests:
Andreas has also reported that it’s working fine on Nokia N9 devices.
The next steps to enable building full apps on Android and iOS are:
Such approach will allow us to build easily Android or iOS apps without having to write a single line of Java or Objective-C code, while providing the full power of Red. At least, that’s the theory, we’ll see in practice if it’s up to our expectations. Also, cross-compilation should be fully available for Android (producing Android apps from any OS), but code signing and app publishing requirements might make it impossible for iOS and require a MacOS X with Xcode for producing apps (if you know workarounds, let us know).
The PIC support should be doable in a few days, the support for shared library generation might take a bit more time. Anyway, theses tasks will need to be multiplexed with Red runtime & compiler implementation, so don’t expect significant progress before a month.
In the meantime, you are welcome to test the ARM port of Red/System and hack Android and upcoming Raspberry Pi devices using it. ;-)
