NDK學(xué)習(xí)之靜態(tài)庫(kù)的編譯與調(diào)用

源代碼全放在新建的jni目錄

編譯的代碼 PrintTest.c

內(nèi)容:

Print.H:

extern?int?Add(int??x,?int??y);

Print.c:

#include?"PrintTest.h"??
??
int??Add(int??x,?int??y)??
{??
????return?x?+?y;??
}

Android.mk：

LOCAL_PATH:=?$(call?my-dir)??
include?$(CLEAR_VARS)??
LOCAL_MODULE????:=?libprint?
LOCAL_SRC_FILES?:=?PrintTest.c??
include?$(BUILD_STATIC_LIBRARY)

Application.mk:

APP_ABI?:=?armeabi

cygwin編譯:ndk-build

objlocal下生成libprint.a文件??,保存好

調(diào)用:

?在一個(gè)動(dòng)態(tài)庫(kù)中調(diào)用他

文件為Use.c:

#include?"PrintTest.h"??
#includeint?UseTest(?int?x??,??int?y?)??
{??
????return?Add(x,?y);??
}

Application.mk:

LOCAL_PATH:=?$(call?my-dir)??
??
#?需要把靜態(tài)庫(kù)導(dǎo)入?
#??
include?$(CLEAR_VARS)??
LOCAL_MODULE????:=?libprint??
LOCAL_SRC_FILES?:=?libprint.a??
include?$(PREBUILT_STATIC_LIBRARY)??
??
#?第二個(gè)為動(dòng)態(tài)庫(kù),在動(dòng)態(tài)庫(kù)中使用我們編譯的靜態(tài)庫(kù)
?
include?$(CLEAR_VARS)??
LOCAL_MODULE????:=?libuse??
LOCAL_SRC_FILES?:=?Use.c??
LOCAL_STATIC_LIBRARIES?:=?libprint
include?$(BUILD_SHARED_LIBRARY)

libprint.a文件移動(dòng)到j(luò)ni目錄

ndk-build：

Administrator@momo-PC /cygdrive/d/cocos/android-ndk-r10c/mycode1
$ ndk-build
[armeabi] Compile thumb ?: use <= Use.c
[armeabi] SharedLibrary ?: libuse.so
[armeabi] Install ? ? ? ?: libuse.so => libs/armeabi/libuse.so
