NDK 8c

构建共享库

切换到armeabi-v7a后,我无法启动gdbserver.我在网上搜索了几个小时但找不到专门处理armeabi-v7a调试问题的话题.

由于使用依赖于它的第三方库,我无法切换到armeabi-v7a.没有它,我会遇到这些错误：

D:\TEMP\ccnnGAqD.s:10427: Error: selected processor does not support Thumb mode `ldrex r6,[r3]'
D:\TEMP\ccnnGAqD.s:10429: Error: selected processor does not support Thumb mode `strex r4,r5,[r3]'

使用此设置：http://mhandroid.wordpress.com/2011/01/23/using-eclipse-for-android-cc-development/之前,使用’armeabi’之前一切正常

我做的唯一更改是将其添加到Application.mk：

APP_ABI := armeabi-v7a

在Android.mk共享库的最底部,我添加了这个：

$(info TARGET_ARCH     = $(TARGET_ARCH))
$(info TARGET_ARCH_ABI = $(TARGET_ARCH_ABI))
$(info TARGET_ABI      = $(TARGET_ABI))

输出如下：

TARGET_ARCH     = arm
TARGET_ARCH_ABI = armeabi-v7a
TARGET_ABI      = android-14-armeabi-v7a

我已经使用了卸载应用程序

adb uninstall com.example.game

AndroidManifest.xml确实有android：debuggable =“true”属性.

在Eclipse中完成“全部清除”,并手动删除./libs和./obj文件夹.然后,ndk-build输出到右侧文件夹(obj / local / armeabi-v7a和libs / armeabi-v7a),并且obj / local / armeabi和libs / armeabi不存在.

但是,这是我运行ndk-gdb时会发生的事情：

user@MACHINENAME /cygdrive/e/projects/game

   This usually means you modified your AndroidManifest.xml to set
   the android:debuggable flag to 'true' but did not rebuild the
   native binaries. Please call 'ndk-build' to do so,*then* re-install to the device!

使用错误的’armeabi’注意“应用程序所针对的ABI”.这是ndk-gdb的相关部分：

get_build_var ()
{
    if [ -z "$GNUMAKE" ] ; then
        GNUMAKE=make
    fi
    $GNUMAKE --no-print-dir -f $ANDROID_NDK_ROOT/build/core/build-local.mk -C $PROJECT DUMP_$1 | tail -1
}

APP_ABIS=`get_build_var APP_ABI`
if [ "$APP_ABIS" != "${APP_ABIS%%all*}" ] ; then
# replace first "all" with all available ABIs
  ALL_ABIS=`get_build_var NDK_ALL_ABIS`
  APP_ABIS_FRONT="${APP_ABIS%%all*}"
  APP_ABIS_BACK="${APP_ABIS#*all}"
  APP_ABIS="${APP_ABIS_FRONT}${ALL_ABIS}${APP_ABIS_BACK}"
fi
log "ABIs targetted by application: $APP_ABIS"

我清楚地在Application.mk中将APP_ABI设置为armeabi-v7a,这是NDK中的一个错误吗？或者我错过了什么？
