如何使用Android NDK编译静态库?

据我所知,正确的方法是 ndk构建 不直接调用编译器。

在 安卓.mk

LOCAL_PATH := $(call my-dir)

# Define vars for library that will be build statically.
include $(CLEAR_VARS)
LOCAL_MODULE := <module_name>
LOCAL_C_INCLUDES := <header_files_path>
LOCAL_SRC_FILES :=  <list_of_src_files>

# Optional compiler flags.
LOCAL_LDLIBS   = -lz -lm
LOCAL_CFLAGS   = -Wall -pedantic -std=c99 -g

include $(BUILD_STATIC_LIBRARY)

# First lib, which will be built statically.
include $(CLEAR_VARS)
LOCAL_MODULE := hello-jni
LOCAL_STATIC_LIBRARIES := <module_name>
LOCAL_C_INCLUDES := <header_files_path>
LOCAL_SRC_FILES := hello-jni.c

include $(BUILD_SHARED_LIBRARY)

如果您想控制在运行ndk build时编译哪些模块,可以创建 应用程序.mk

APP_MODULES := <module_name_1> <module_name_2> ... <module_name_n>

用它吗?

默认情况下,NDK只构建可执行文件和共享库(当然还有它们的依赖项)。但是,您可以通过在Application.mk中显式引用NDK来强制它构建独立的静态库。

假设您的静态库模块是LOCAL\u module:=libXYZ,将以下行添加到 应用程序.mk (如果Android.mk不存在,则在与Android.mk相同的文件夹中创建该文件):

APP_MODULES := XYZ

注意,APP\u MODULES值不包括静态库模块名称中包含的lib前缀。

ndk-build APP_MODULES=XYZ

include $(BUILD_SHARED_LIBRARY)

到

include $(BUILD_STATIC_LIBRARY)
