    MIPS

    edited January 2015 in General questions
    How easy would it be to add MIPS output for Android (in addition to Arm and x86 libs) ?

    I'm only asking because this kind of gadget looks pretty useful and it also opens up more cheap tablets.

      As far as I remember, not so easy, due to different endianness of byte interpreted.

      Arm is bi-endian too - most OS just fall back to little-endian when there is a choice.

      "Yes for all ARM/X86/MIPS devices I know of, at least NDK toolchain is
      configured to little-endian only, although it's a good practice to check
      endianess at runtime (or assert the fact) so your C/C++ code is more
      portable."

      " I.4. 'mips'

      This is the name of an ABI for MIPS-based CPUs that support *at* *least* the MIPS32r1 instruction set. The ABI includes the following features:

      - MIPS32 revision 1 ISA
      - Little-Endian
      - O32
      - Hard-Float
      - no DSP application specific extensions"

      Just including little endian should do fine and add a few hundred more compatible devices.

      If it gets added then I'll buy one of the boards and check out compatibility.

      @ar2rsawseen - is it simply a matter of adding "mips" to the object types?

      Basically yes, additionally to "armeabi armeabi-v7a x86" you would also need to add mips to all these files:

      https://github.com/gideros/gideros/search?utf8=✓&q=armeabi+armeabi-v7a+x86

      Build android libs using scripts inside scripts directory
      bash buildandroidlibs.sh
bash buildandroidso.sh
bash buildandroidplugins.sh
      or for windows correspondingly bat files

      and try it out on the mips tablet :)

      If you can be persuaded to add it to the next build then I'll get hold of a MIPS device to test if you like? ;)

      It can't hurt as it only increased the number of devices whilst the build size will only go up slightly.

      @ar2rsawseen I saw this:

      APP_ABI := all

      This includes all of them ?

      Most probably it include even more :D

      Maybe, :)

      But seriously I think might be best to include them all and have the user just remove the folders containing those they don't want directly?
