請問大家ndk中LOCAL_SHARED_LIBRARIES LOCAL_LDLIBS什么區別啊
我先是編譯了一個.so 然后在此次編譯的使用調用，請問用LOCAL_SHARED_LIBRARIES和LOCAL_LDLIBS什么區別啊，我用后者能編譯通過，用前者不行呢，謝謝！！
1.共享庫放在其他程序里面也應該可以調用 非共享庫只能在本程序調用
我想是這樣的 不知道對不對
2.我用LOCAL_LDLIBS，編譯的時候，提示：ndroideabi/bin/ld.exe: cannot find -lssl
3.我剛看了下源碼，目錄/framework/base/media/jni下有個Android.mk文件，里面有這樣一句話:LOCAL_LDLIBS := -lpthread;這讓我聯想到了編譯c線程程序時需要加編譯參數-lpthread(引入libpthread.so共享庫)。 LOCAL_LDLIBS := -lpthread作用也是引入libpthread.so庫，也是不知兩者區別在哪里，，求高手解答。。。。。
4.剛查了下，有的人講：“由於要調用第三方庫，所以用到了 LOCAL_LDLIBS” 。
5.in your case, in your “mydrdoid”, if you use:LOCAL_LDLIBS := -lskia” …then, libskia.so *need not* be rebuilt.
whereas, if you use:LOCAL_SHARED_LIBRARIES := libskia … then libskia.so *will* be rebuilt if there are any changes in it’s dependencies.

thanks for your explanation
also i found that LOCAL_LDLIBS in mydroid can only work for
HOST_SHARED_LIBS
but not for TARGET SHARED LIBS
thanks
