生成共享库

我不能让gdbserver的要切换到armeabi-V7A之后再启动。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。

I can't get gdbserver to start anymore after switching to armeabi-v7a. I've searched online for hours but can't find a topic that deals specifically with armeabi-v7a debugging issues.

我没有选择，切换到armeabi-V7A由于使用取决于其第三方库。没有它，我得到这类错误的：

I have no choice to switch to armeabi-v7a due to using a third party library which depends on it. Without it, I get these kind of errors:

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]'

这是所有罚款armeabi，使用此设置工作之前：http://mhandroid.word$p$pss.com/2011/01/23/using-eclipse-for-android-cc-development/

我所做的唯一变化就是把它添加到Application.mk：

The only change I've made is to add this to Application.mk:

APP_ABI := armeabi-v7a

在共享库Android.mk我说这的最底层：

At the very bottom of the shared library Android.mk I added this:

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

它输出以下内容：

which outputs the following:

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

我已经卸载使用的应用程序

I've uninstalled the app using

adb uninstall com.example.game

AndroidManifest.xml中确实有机器人：可调试=真正的财产

AndroidManifest.xml does have the android:debuggable="true" property.

完成Eclipse的一个干净所有，并手动删除./libs和./obj文件夹。然后，NDK，生成输出到正确的文件夹（OBJ /本地/ armeabi-V7A和库/ armeabi-V7A）和OBJ /本地/ armeabi和库/ armeabi 不存在。

Done a "clean all" in Eclipse, and manually deleted the ./libs and ./obj folders. Then, ndk-build outputs to the right folders (obj/local/armeabi-v7a and libs/armeabi-v7a), and obj/local/armeabi and libs/armeabi do not exist.

不过，这里是当我运行NDK-gdb的会发生什么：

However, here's what happens when I run ndk-gdb:

user@MACHINENAME /cygdrive/e/projects/game
$ ndk-gdb-eclipse --force --verbose
Android NDK installation path: /cygdrive/e/projects/sdks/android-ndk
Using default adb command: /cygdrive/e/projects/sdks/android-sdk/platform-tools/adb
ADB version found: Android Debug Bridge version 1.0.31
Using ADB flags:
Using auto-detected project path: .
Found package name: com.example.game
ABIs targetted by application: armeabi
Device API Level: 15
Device CPU ABIs: armeabi-v7a armeabi
Compatible device ABI: armeabi
Using gdb setup init: ./libs/armeabi/gdb.setup
Using toolchain prefix: /cygdrive/e/projects/sdks/android-ndk/toolchains/arm-linux-androideabi-4.6/prebuilt/windows/bin/arm-linux-androideabi-
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!

注意使用了错误的armeabi的按应用针对性的ABI。以下是有关部分NDK-gdb的：

Notice the "ABIs targetted by application" using the wrong 'armeabi'. Here's the relevant part of ndk-gdb:

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APP_ABI为armeabi-V7A在Application.mk，所以这是在NDK中的错误？还是我失去了一些东西？

I clearly set APP_ABI to armeabi-v7a in Application.mk, so is this a bug in the NDK? Or am I missing something?
