对共享库的Android NDK -Linker错误。

我想弄清楚为什么我一直在android中附带共享库中声明的函数未定义引用。对共享库的Android NDK -Linker错误。

我application.mk和根android.mk

APP_MODULES := adhoc 
APP_STL := gnustl_shared 
NDK_TOOLCHAIN_VERSION=clang3.1 
APP_OPTIM := debug 

CUR_PATH := $(call my-dir) 
LOCAL_CPPFLAGS += -std-c++11 -Wwrite-strings 

include $(CUR_PATH)/native/adhoc/Android.mk

即席Android.mk

LOCAL_PATH := $(call my-dir) 
updater_src_files := \ 
    install.cpp\ 
    sha1.cpp\ 
    addhoc_lib.cpp 


include $(CLEAR_VARS) 

LOCAL_SRC_FILES := $(updater_src_files) 

inc_path = $(NDK_ROOT)/../AndroidSource/system/core/include \ 
$(NDK_ROOT)/../AndroidSource/hardware/libhardware_legacy/include 

LOCAL_C_INCLUDES += $(inc_path) 

LOCAL_CFLAGS := -DINTERNAL_SHA1 -DCONFIG_CRYPTO_INTERNAL -DCONFIG_NO_T_PRF -DCONFIG_NO_TLS_PRF -std=c++11 -Wc++11-extensions -Wno-deprecated-writable-strings 

LOCAL_STATIC_LIBRARIES := libedify 

LOCAL_SHARED_LIBRARIES := libcutils\ 
       libhardware_legacy\ 
       libc\ 
       libnetutils\ 
       libsysutils 

LOCAL_MODULE := adhoc 

include $(BUILD_SHARED_LIBRARY) 

$(call import-add-path, $(LOCAL_PATH)) 
$(call import-module, edify)

和即席/陶冶/ android.mk

LOCAL_PATH := $(call my-dir) 

edify_src_files := \ 
    lexer.l \ 
    parser.y \ 
    expr.c 

include $(CLEAR_VARS) 

LOCAL_SRC_FILES := $(edify_src_files) 

LOCAL_CFLAGS := $(edify_cflags) 
LOCAL_MODULE := edify 

include $(BUILD_STATIC_LIBRARY)

我得到的输出ndk-build -BV = 1 like：

SharedLibrary : libadhoc.so

如果您使用C++代码，则添加C PLUS PLUS标志。

#ifdef __cplusplus 
extern "C" { 
#endif 


#ifdef __cplusplus 
} 
#endif

也看看下面的帖子。 android ndk undefined reference to a method

嗯，我通过从手机上复制库并为构建系统提供了一条路径来实现它。我已经用extern“C”包装了头文件。 – 2013-03-12 18:16:59
