请问大家ndk中LOCAL_SHARED_LIBRARIES LOCAL_LDLIBS什么区别
请问大家ndk中LOCAL_SHARED_LIBRARIES LOCAL_LDLIBS什么区别啊
我先是编译了一个.so 然后在此次编译的使用调用，请问用LOCAL_SHARED_LIBRARIES和LOCAL_LDLIBS什么区别啊，我用后者能编译通过，用前者不行呢，谢谢！！
1.共享库放在其他程序里面也应该可以调用 非共享库只能在本程序调用
我想是这样的 不知道对不对
2.我用LOCAL_LDLIBS，编译的时候，提示：ndroideabi/bin/ld.exe: cannot find -lssl
3.我刚看了下源码，目录/framework/base/media/jni下有个Android.mk文件，里面有这样一句话:LOCAL_LDLIBS := -lpthread;这让我联想到了编译c线程程序时需要加编译参数-lpthread(引入libpthread.so共享库)。 LOCAL_LDLIBS := -lpthread作用也是引入libpthread.so库，也是不知两者区别在哪里，，求高手解答。。。。。
4.刚查了下，有的人讲：“由于要调用第三方库，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
