链接android ndk中的静态库

问题描述

| 我正在尝试从android ndk示例libs文件夹中的http://developer.nvidia.com/tegra-resources编译nvfile库。无论如何，由于我实际上并不需要整个库套件，因此我抽出了所需的库，其中似乎有依赖关系。这是用于编译它们的Android.mk文件。

include $(CLEAR_VARS)
LOCAL_MODULE     := nvthread
LOCAL_CFLAGS     := -Wall -g
LOCAL_LDFLAGS    := -Wl,-Map,xxx.map
LOCAL_SRC_FILES  := nv/nv_thread/nv_thread.c
LOCAL_C_INCLUDES := nv

include $(BUILD_STATIC_LIBRARY)


include $(CLEAR_VARS)
LOCAL_MODULE           := nvfile
LOCAL_CFLAGS           := -Wall -g
LOCAL_LDFLAGS          := -Wl,xxx.map
LOCAL_SRC_FILES        := nv/nv_file/nv_file.c
LOCAL_C_INCLUDES       := nv
LOCAL_STATIC_LIBRARIES := nvthread nvapkfile

include $(BUILD_STATIC_LIBRARY)


include $(CLEAR_VARS)
LOCAL_MODULE           := nvapkfile
LOCAL_CFLAGS           := -Wall -g
LOCAL_LDFLAGS          := -Wl,xxx.map
LOCAL_SRC_FILES        := nv/nv_apk_file/nv_apk_file.c
LOCAL_C_INCLUDES       := nv
LOCAL_STATIC_LIBRARIES := nvthread

include $(BUILD_STATIC_LIBRARY)

nvapkfile库似乎可以与nvthread很好地链接，但是nvfile库似乎根本不想链接到nvapkfile库。源代码中的包含文件可以正常工作，只是每当我尝试对其进行编译时，都会得到未定义的引用。这是输出示例：

我根本没有修改实际的c或h文件。但作为参考，这里是相关的C文件的一部分：

#include \"nv_file.h\"
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#ifdef ANDROID
#include \"../nv_apk_file/nv_apk_file.h\"
#define SUPPORT_APK 1
#include <unistd.h>
#endif

//...

void  NvFInit()
{
#ifdef SUPPORT_APK
    NvAPKInit();
#endif
}

这是nv_file.c的22-32和46-51行 如您所见，标题已包含在内，但没有链接。有人知道我在这里缺少什么吗？谢谢。
