Build a Make based C++ project using Android NDK

Question

I need to build csparse library for an Android project. The project supports Make build system.

I am not familiar with use of NDK for Make build. I have used Androids CMake toolchain for building CMake based projects.

I am looking for pointers to usage of NDK for building C++ projects based on Make. I do not want to manually write a CMakeLists.txt for building the project with CMake toolchain because there are too many source files in the csparse project!

Any help is appreciated!

Answer 1

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 explicitly covers traditional make projects.

Answer 2

OK, It wasn't so difficult. It seems CSparse is a self-contained and does not depend on other linear-algebra libraries such as CHOLMOD, BLAS, LAPACK, Metis... etc

Here is the CMakeLists.txt file from my Android project :

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-lib

        log)

target_link_libraries( # Specifies the target library.
        native-lib

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

        csparse-lib
        )

I hope this answer helps others.
