code changes [2014-05-14: no longer needed]

• cpu.c

  • added machine/
    • #include <machine/cpu-features.h>
      • this is not needed after adding
        • LOCAL_STATIC_LIBRARIES := cpufeatures to libwebp-0.4.0.mk

• this later caused to following while compiling for armeabi-v7a:

  • libwebp-0.4.0/src/dsp/cpu.c

:60:3: error: unknown type name 'AndroidCpuFamily'
:63:27: error: 'ANDROID_CPU_FAMILY_ARM' undeclared (first use in this function)
:64:34: error: 'ANDROID_CPU_ARM_FEATURE_NEON' undeclared (first use in this function)

• added
  • LOCAL_STATIC_LIBRARIES := cpufeaturesto libwebp-0.4.0.mk
    • #include <cpu-features.h> in libwebp-0.4.0/src/dsp/cpu.c
      • compiled and linked for
        • armeabi
      • armeabi-v7a : Assembler messages:
        • [armeabi-v7a] Compile thumb : webp <= dec_neon.c
        • Error: selected processor does not support Thumb mode ...
          • resolved after adding -mfpu=neon
    • and add to the end of Android_R4.2.0.mk
      • $(call import-module,android/cpufeatures

[armeabi-v7a] StaticLibrary  : libwebp.a
[armeabi-v7a] SharedLibrary  : libjsqlite.so
[armeabi-v7a] Install        : libjsqlite.so => libs/armeabi-v7a/libjsqlite.so

• at the moment we are happy
  • [x86] is now compiling
