的Android NDK：建立我的靜態庫

Question

我在JNI文件夾這些文件：

• Android.mk

• Application.mk

• m_lanczos.c

• m_lanczos .h

• sresolution.cp p

，我只想用我的圖書館像resolution.cpp：

#include"m_lanczos.h" 

還有什麼我必須在Android.mk補充的嗎？謝謝！

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

LOCAL_MODULE := super 
LOCAL_SRC_FILES := sresolution.cpp 
LOCAL_LDLIBS += -llog -ldl 

include $(BUILD_SHARED_LIBRARY) 

Answer 1

有兩件事情是錯的：

1. 你已經忘了編譯m_lanczos.c：
   那麼你的Android.mk應該是這樣的：

   LOCAL_PATH := $(call my-dir) 
   include $(CLEAR_VARS) 
   
   LOCAL_MODULE := super 
   LOCAL_SRC_FILES := sresolution.cpp m_lanczos.c 
   LOCAL_LDLIBS += -llog -ldl 
   
   include $(BUILD_SHARED_LIBRARY) 
   

2. m_lanczos是一個STATIC_LIBRARY：
   然後，你必須建立它，幷包括它：

   LOCAL_PATH := $(call my-dir) 
   
   include $(CLEAR_VARS)  
   LOCAL_MODULE := m_lanczos 
   LOCAL_SRC_FILES := m_lanczos.c 
   LOCAL_LDLIBS +=   #needed librarys for m_lanczos, probably nothing  
   include $(BUILD_STATIC_LIBRARY) 
   
   include $(CLEAR_VARS)   
   LOCAL_MODULE := super 
   LOCAL_SRC_FILES := sresolution.cpp 
   LOCAL_LDLIBS += -llog -ldl 
   LOCAL_STATIC_LIBRARIES := m_lanczos 
   include $(BUILD_SHARED_LIBRARY) 
   

但我認爲這將是第一個， 我希望我幫助:)
