在Android.mk中將多個.c文件鏈接在一起

Question

如何在Android.mk文件中鏈接或“使用”多個.c文件？

目前看起來像這樣

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := ndk_demo
LOCAL_SRC_FILES := gnutls-3.0.12/lib/debug.c
include $(BUILD_SHARED_LIBRARY)

但是，當我嘗試ndk-build時，它總是拋出此錯誤

Compile thumb  : ndk_demo <= debug.c

我如何將u64.h之類的文件包含到Android.mk中，以免出現此類文件或目錄錯誤？ 還是我會以錯誤的方式處理？

Answer 1

如果要指定幾個c文件，語法如下：

LOCAL_SRC_FILES := \
    my_c_file1.c \
    my_c_file1.c \
    my_c_file2.c \
    my_last_c_file.c

使用以下偽指令將頭文件的路徑添加到make文件中：

LOCAL_C_INCLUDES := \
    /my_path1_to_h_files/ \
    /my_path2_to_h_files/ \
    /my_pathN_to_h_files/

並且，如果您的模塊使用一些共享庫進行鏈接，則可以添加以下內容：

LOCAL_SHARED_LIBRARIES := \
    lib1 \
    lib2 \
    lib3
