如何从命令行使用 cmake 为 root Android 设备制作可执行文件？
How to use cmake from command line to make an executable for rooted Android device?
我想要 运行 一个简单的可执行文件，当我从 adb shell 执行它时应该打印 "Hello Cmake"。为此，我用 CMakeLists.txt 文件创建了一个简单的 c++ 文件，如下所示：
hello.cpp
#include <iostream>
int main(int, char**) {
std::cout << "Hello, CMake!\n";
}
CMakeLists.txt
cmake_minimum_required(VERSION 3.4.1)
add_library( # Sets the name of the library.
hello_cmake
# Sets the library as a static library.
STATIC
# Provides a relative path to your source file(s).
hello.cpp )
我已经尝试 运行 在终端中执行以下命令：
cmake D:/Development/CMAKE/HelloCmake/ -G Ninja \
-DANDROID_TOOLCHAIN_NAME=aarch64-linux-android29-clang++ \
-DANDROID_PLATFORM=29 \
-DCMAKE_CACHEFILE_DIR=D:/Development/CMAKE/HelloCmake/build \
-DCMAKE_MAKE_PROGRAM=D:/Sdk/cmake/3.10.2.4988404/bin/ninja.exe \
-DCMAKE_C_COMPILER=D:/Sdk/ndk-bundle/toolchains/llvm/prebuilt/windows-x86_64/bin/aarch64-linux-android29-clang \
-DCMAKE_CXX_COMPILER=D:/Sdk/ndk-bundle/toolchains/llvm/prebuilt/windows-x86_64/bin/aarch64-linux-android29-clang++

我有 运行 D:\Sdk\cmake.10.2.4988404\bin\ninja.exe -C arm64-v8a 命令来制作目标静态库，但我得到 libhello_cmake.a 即 current ar archive.
我认为要生成可执行文件，CMakeLists.txt add_library 行应该替换为其他内容吗？
有几个问题：
静态库并不意味着直接运行。如果你想构建一个你可以 运行 的可执行文件，你应该使用 add_executable 而不是 add_library.
当您调用 cmake 时，您应该设置 CMAKE_TOOLCHAIN_FILE 选项来指定要使用的工具链文件，可能还有其他选项。要了解 Android Studio / Gradle 使用的是什么，您可以使用 Android Studio 的项目向导创建一个支持 C++ 的 Android 项目并查看 cmake_build_command.txt 构建该项目时生成的文件。
运行宁cmake后还需要运行ninja。该命令类似于 ninja -C <directory containing build files generated by cmake>.
