NDK Android的 - 不能在同一时间建立的ARMv5和V7 [英] NDK Android - Can't build ARMv5 and V7 at the same time

问题描述

我现在面临一个奇怪的问题。
我建立一个共享库我的Andr​​oid应用程序。

我不能同时既建立的ARMv5和ARMv7。
如果我这样做，我得到了很多错误，在对第二次运行我的源文件（当NDK构建的ARMv7 LIB），如：

  FinderPatternInfo.o：previous定义在这里
多重定义...
 

我的 Application.mk

  APP_ABI：= armeabi armeabi，V7A
APP_PLATFORM：=机器人-8
APP_STL：= stlport_static
APP_CPPFLAGS + = -fexceptions
 

它完美，如果我只设置APP_ABI：= armeabi或APP_ABI：= armeabi-V7A ..

你知道吗？
感谢你的帮助，

编辑：Android.mk

  LOCAL_PATH：= $（叫我-DIR）
包括$（CLEAR_VARS）
LOCAL_MODULE：= MyModule的MY_LOCAL_INCLUDED_FILES + = $（$通配符（LOCAL_PATH）/ *高）
MY_LOCAL_INCLUDED_FILES + = $（$通配符（LOCAL_PATH）/ *。HPP）
MY_LOCAL_INCLUDED_FILES + = $（$通配符（LOCAL_PATH）/ BIGINT / *高）
......（很多包括）LOCAL_C_INCLUDES：= $（SUBST JNI /，$（MY_LOCAL_INCLUDED_FILES））MY_LOCAL_SRC_FILES + = $（$通配符（LOCAL_PATH）/ * C）
MY_LOCAL_SRC_FILES + = $（$通配符（LOCAL_PATH）/ *。CPP）
MY_LOCAL_SRC_FILES + = $（$通配符（LOCAL_PATH）/ BIGINT / * C）
....（很多cpp文件）LOCAL_SRC_FILES：= $（SUBST JNI /，$（MY_LOCAL_SRC_FILES））LOCAL_CFLAGS：= -DNO_ICONV包括$（BUILD_SHARED_LIBRARY）
 

解决方案

而Android系统让您解析一次Android.mk为每一个目标，所以你的 MY_LOCAL_SRC_FILES 获取全套所有的。 c和.cpp文件两次当有两个目标，但每次只有一个时，有一个单一的目标。

如果您的第一个 MY_LOCAL_SRC_FILES 分配使用：=代替+ =，我认为这将解决这个问题。

I'm facing a weird problem. I'm building a shared library for my Android application.

I can't build both armv5 and armv7 at the same time. If I do so, I get a lot of errors on my source files at the second run (when the ndk build the armV7 lib) like:

FinderPatternInfo.o: previous definition here
multiple definition of ...

My Application.mk

APP_ABI             := armeabi armeabi-v7a
APP_PLATFORM        := android-8
APP_STL             := stlport_static
APP_CPPFLAGS        += -fexceptions

It works perfectly if I only set APP_ABI := armeabi or APP_ABI := armeabi-v7a..

Any idea ? Thank you for your help,

EDIT: Android.mk

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE            := MyModule

MY_LOCAL_INCLUDED_FILES += $(wildcard $(LOCAL_PATH)/*.h)
MY_LOCAL_INCLUDED_FILES += $(wildcard $(LOCAL_PATH)/*.hpp)
MY_LOCAL_INCLUDED_FILES += $(wildcard $(LOCAL_PATH)/bigint/*.h)
... (many includes)

LOCAL_C_INCLUDES        :=  $(subst jni/, , $(MY_LOCAL_INCLUDED_FILES))

MY_LOCAL_SRC_FILES += $(wildcard $(LOCAL_PATH)/*.c)
MY_LOCAL_SRC_FILES += $(wildcard $(LOCAL_PATH)/*.cpp)
MY_LOCAL_SRC_FILES += $(wildcard $(LOCAL_PATH)/bigint/*.c)
.... (many cpp files)

LOCAL_SRC_FILES     :=  $(subst jni/, , $(MY_LOCAL_SRC_FILES))

LOCAL_CFLAGS        := -DNO_ICONV

include $(BUILD_SHARED_LIBRARY)

解决方案

The Android make system parses your Android.mk once for each target, so your MY_LOCAL_SRC_FILES gets a full set of all of your .c and .cpp files twice when there are two targets, but only one of each when there's a single target.

If your first MY_LOCAL_SRC_FILES assignment used := instead of +=, I think it would fix the problem.
