Question

Application.mk

APP_STL := gnustl_static
APP_ABI := all

Android.mk

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE := libz
LOCAL_SRC_FILES := ../prebuild/libz.a
LOCAL_EXPORT_C_INCLUDES := ../prebuild/include/
include $(PREBUILT_STATIC_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := libssl
LOCAL_SRC_FILES := ../prebuild/libssl.a
LOCAL_EXPORT_C_INCLUDES := ../prebuild/include
include $(PREBUILT_STATIC_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := libcrypto
LOCAL_SRC_FILES := ../prebuild/libcrypto.a
LOCAL_EXPORT_C_INCLUDES := ../prebuild/include
include $(PREBUILT_STATIC_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := libjson-c
LOCAL_SRC_FILES := ../prebuild/libjson-c.a
LOCAL_EXPORT_C_INCLUDES := ../prebuild/include
include $(PREBUILT_STATIC_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := libcurl
LOCAL_SRC_FILES := ../prebuild/include/libcurlall/$(TARGET_ARCH_ABI)/libcurl.a
LOCAL_EXPORT_C_INCLUDES := ../prebuild/include
include $(PREBUILT_STATIC_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := curl-ndk
LOCAL_SRC_FILES := ../cpp/curl-http.cpp
LOCAL_STATIC_LIBRARIES := libcurl libssl libcrypto libz libjson-c
LOCAL_LDLIBS := -lz -llog -ljnigraphics
include $(BUILD_SHARED_LIBRARY)

清理项目，我试图交叉编译NDK，然后显示以下错误：

/Volumes/Work/Android/Projects/app/src/main/jni/../prebuild/libz.a: error adding symbols: File in wrong format
clang++: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [/Volumes/Work/Android/Projects/app/src/main/obj/local/arm64-v8a/libcurl-ndk.so] Error 1

它工作在32位精细但64位显示错误

提前致谢

您正在为所有ABI使用一个预建。您需要为每个目标ABI预建一个。编写预构建模块的典型方法如下：

include $(CLEAR_VARS)
LOCAL_MODULE := libz
LOCAL_SRC_FILES := ../prebuild/$(TARGET_ARCH_ABI)/libz.a
LOCAL_EXPORT_C_INCLUDES := ../prebuild/include/
include $(PREBUILT_STATIC_LIBRARY)

然后你可以预制/ armeabi-v7a / libz.a，prebuild / arm64-v8a / libz.a等。禁用你不想构建的ABI（或者没有prebuilts for）在Application.mk中使用APP_ABI。

NDK构建错误（错误：链接器命令失败，退出代码为1（使用-v查看调用））
