Question

我已经使用ndk工具链成功编译了多个静态库，并将它们链接到我自己的项目中。我必须使用许多cpp文件，他们需要协议缓冲区和ZeroMQ作为库来成功编译。链接协议缓冲区效果很好，但是，当我链接到ZeroMQ时，我收到以下错误：

C:/Users/x/ndk/toolchains/arm-linux-androideabi-4.9/prebuilt/windows-  x86_64/bin/../lib/gcc/arm-linux-androideabi/4.9/../../../../arm-linux-   androideabi/bin/ld.exe: error: ./zmq/lib/libzmq.a(libzmq
_la-zmq.o): incompatible target
collect2.exe: error: ld returned 1 exit status
make.exe: *** [C:/Users/x/Workspace/y/app/src/main//obj/local/armeabi-  v7a/libZ.so] Error 1

我已将x，y，z的个人信息替换为明确原因。

我使用Windows 8.1与Android Studio 1.1 RC1和NDK10d。我在Ubuntu和Debian系统上编译了这些库（尝试了不同的库）。两者都使用相同的手臂工具链。

要编译ZeroMQ，我按照official page中的步骤进行操作。我试过zeromq3-x和zeromq4-x。我尝试了提到的ndk8和新的ndk10d。

我的 Application.mk ：

APP_STL := gnustl_static     #tried: c++_static/shared stlport_static/shared
APP_PLATFORM := android-21
APP_USE_CPP0X := true  #tried to omit
APP_CXXFLAGS := -std=gnu++11
APP_CPPFLAGS := -frtti -fexceptions --std=c++11
APP_ABI := armeabi-v7a             #tried different like armeabi, all, x86 - obviously only arm should work
NDK_TOOLCHAIN_VERSION := 4.9

Android.mk 没有要编译的重要文件，因为它会在首次需要zmq时崩溃：

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

LOCAL_MODULE := ../jni/protobuf
LOCAL_SRC_FILES := ../jni/protobuf/libprotobuf.a
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include

include $(PREBUILT_STATIC_LIBRARY)

 LOCAL_STATIC_LIBRARIES := zmq protobuf

 include $(BUILD_SHARED_LIBRARY)

静态库中的 objdump 看起来像这样

libzmq_la-address.o:     file format elf64-x86-64
architecture: i386:x86-64, flags 0x00000011:
HAS_RELOC, HAS_SYMS
start address 0x0000000000000000

我会省略其他的因为它们都是一样的。有一个更好的方法来转储所有信息，包含有关架构的更多细节，但我再也找不到了。

如果您了解更好的方式，可以告诉我，我会添加更多信息。
