编译Android SDK时遇到以下问题：

1. on-trivial designated initializers not supported

target thumb C++: gralloc.goldfish <= development/tools/emulator/opengl/system/gralloc/gralloc.cpp
development/tools/emulator/opengl/system/gralloc/gralloc.cpp: In function ‘int gralloc_unregister_buffer(const gralloc_module_t*, buffer_handle_t)‘:
development/tools/emulator/opengl/system/gralloc/gralloc.cpp:583:26: warning: converting to non-pointer type ‘int‘ from NULL [-Wconversion-null]
development/tools/emulator/opengl/system/gralloc/gralloc.cpp: At global scope:
development/tools/emulator/opengl/system/gralloc/gralloc.cpp:900:1: sorry, unimplemented: non-trivial designated initializers not supported
development/tools/emulator/opengl/system/gralloc/gralloc.cpp:900:1: warning: missing initializer for member ‘gralloc_module_t::reserved_proc‘ [-Wmissing-field-initializers]
make: *** [out/target/product/generic/obj/SHARED_LIBRARIES/gralloc.goldfish_intermediates/gralloc.o] Error 1

解决方法： 结构体的其中一个成员getphys未提供初始化，加上就ok了：

struct private_module_t HAL_MODULE_INFO_SYM = {
    base: {
        common: {
            tag: HARDWARE_MODULE_TAG,
            version_major: 1,
            version_minor: 0,
            id: GRALLOC_HARDWARE_MODULE_ID,
            name: "Graphics Memory Allocator Module",
            author: "The Android Open Source Project",
            methods: &gralloc_module_methods,
            dso: NULL,
            reserved: {0, }
        },
        registerBuffer: gralloc_register_buffer,
        unregisterBuffer: gralloc_unregister_buffer,
        lock: gralloc_lock,
        unlock: gralloc_unlock,
        perform: NULL,

        getphys: NULL,
        reserved_proc : {NULL, }
    }
};
