安卓NDK调试: armeabi-v7a not working

Question

eclipse /Cygwin

NDK 8c

构建共享库

切换到 armeabi-v7a 后，我无法再启动 gdbserver。我在网上搜索了几个小时，但找不到专门处理 armeabi-v7a 调试问题的主题。

由于使用依赖于它的第三方库，我别无选择地切换到 armeabi-v7a。没有它，我会得到这些错误:

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]'

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

我所做的唯一更改是将其添加到 Application.mk:

APP_ABI := armeabi-v7a

在共享库 Android.mk 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

我已经卸载了应用

adb uninstall com.example.game

AndroidManifest.xml 确实有 android:debuggable="true"属性。

在 Eclipse 中完成“全部清理”，并手动删除 ./libs 和 ./obj 文件夹。然后，ndk-build 输出到正确的文件夹(obj/local/armeabi-v7a 和 libs/armeabi-v7a)，而 obj/local/armeabi 和 libs/armeabi 不存在。

但是，当我运行 ndk-gdb 时会发生以下情况:

user@MACHINENAME /cygdrive/e/projects/game
$ ndk-gdb-eclipse --force --verbose

Using app out directory: ./obj/local/armeabi
Found debuggable flag: true
ERROR: Could not find gdbserver binary under ./libs/armeabi
   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!

请注意“ABIs targeted by application”使用了错误的“armeabi”。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"

我在Application.mk中明明设置了APP_ABI为armeabi-v7a，请问这是NDK的bug吗？还是我遗漏了什么？

Answer 1

我遇到了同样的问题。我在 this article 之后配置了 Eclipse .然后我从 armeabi 改变至 armeabi-v7a .然后我无法调试。

我解决了这个问题:
1) 您必须修复“调试配置”中的文件夹

• 主标签更改 ...obj/local/armeabi/app_process to ...obj/local/armeabi-v7a/app_process
• 调试器选项卡更改 ...obj/local/armeabi/gdb2.setup to obj/local/armeabi-v7a/gdb2.setup
• 调试器选项卡更改 .../toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gdb to toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gdb

2) 这可能是一种解决方法，但它确实有效。在“调试配置”->Debugger->Shared Libraries add <project path>/obj/local/armeabi-v7a并选中“自动加载共享库符号”
