使用 Android NDK 构建基于 Make 的 C++ 项目

Question

我需要为 Android 项目构建 csparse library。项目支持Make构建系统。

我不熟悉 Make build 中 NDK 的使用。我使用 Androids CMake 工具链 构建基于 CMake 的项目。

我正在寻找有关使用 NDK 构建基于 Make 的 C++ 项目的指南。我不想手动写一个CMakeLists.txt用于使用CMake工具链构建项目，因为csparse项目中的源文件太多了！

感谢任何帮助！

好的，没那么难。似乎 CSparse 是一个独立的，不依赖于其他线性代数库，如 CHOLMOD、BLAS、LAPACK、Metis 等

这是我的 Android 项目中的 CMakeLists.txt 文件：

cmake_minimum_required(VERSION 3.4.1)
include_directories(
        ${CMAKE_CURRENT_SOURCE_DIR}/include/CSparse/Source
)

add_library( # Sets the name of the library.
        csparse-lib

        # Sets the library as a shared library.
        SHARED

        # Provides a relative path to your source file(s).
        include/CSparse/Source/cs_add.c

add_library(native-lib SHARED native-lib.cpp)



find_library( # Sets the name of the path variable.

        log)

target_link_libraries( # Specifies the target library.

        # Links the target library to the log library
        # included in the NDK.
        ${log-lib}

        csparse-lib
        )

https://developer.android.com/ndk/guides/other_build_systems covers using the NDK with build systems other than ndk-build and CMake. The last section 明确涵盖传统的 make 项目。
