编译frameworks\native\services\surfaceflinger\tests\resize

 mmm frameworks/native/services/surfaceflinger/tests/resize/遇到几个错误,这里面讲一下解决过程,有一部分参考网络。感谢。


1、问题:

frameworks/native/services/surfaceflinger/tests/resize/resize.cpp:50:26: error: aggregate 'ANativeWindow_Buffer outBuffer' has incomplete type and cannot be defined

解决:

在resize.cpp中,添加#include <android/native_window.h>

2、问题:

frameworks/native/services/surfaceflinger/tests/resize/resize.cpp:58:29: error: no matching function for call to 'android::Surface::lock(ANativeWindow_Buffer*)'


解决:

surface->lock(&outBuffer);  ---》surface->lock(&outBuffer, NULL);


3、问题:

frameworks/native/services/surfaceflinger/tests/resize/resize.cpp:70:1: error: expected '}' at end of input 。。。

解决:

最后加一个“}”


4、问题:

out/target/product/msm8909/obj/lib/crtbegin_dynamic.o:crtbegin.c:function _start: error: undefined reference to 'main'
collect2: error: ld returned 1 exit status

解决:

屏蔽//namespace android { 

//}

5、问题:

error: undefined reference to 'android::ProcessState::self()'

解决:

android.mk中加入:

LOCAL_SHARED_LIBRARIES := \
libcutils \
libutils \
    libui \
    libgui \
    libbinder


最终编译通过了!真够费劲的。
