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]'
使用此设置之前,使用'armeabi'之前一切正常:http://mhandroid.wordpress.com/2011/01/23/using-eclipse-for-android-cc-development/
我所做的唯一改变是将其添加到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))
输出以下内容:
TARGET_ARCH = arm
TARGET_ARCH_ABI = armeabi-v7a
TARGET_ABI = android-14-armeabi-v7a
我已使用
卸载了该应用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),obj / local / armeabi和libs / armeabi 不存在。
然而,这是我运行ndk-gdb时发生的事情:
user@MACHINENAME /cygdrive/e/projects/game
$ ndk-gdb-eclipse --force --verbose

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"
我在Application.mk中清楚地将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?
答案 0 :(得分:0)
我有同样的问题。我在本文后面配置了eclipse: http://mhandroid.wordpress.com/2011/01/23/using-eclipse-for-android-cc-development/ 然后我从armeabi变为armeabi-v7a。然后我无法调试。
我解决了这个问题:
1)您必须在“调试配置”
2)可能这是解决方法,但它确实有效。在“调试配置” - > Debugger->共享库中添加/ obj / local / armeabi-v7a并选中“自动加载共享库符号”
