前言#

上篇文章讲了如何在termux上快速安装arch linux，然后就可以玩一些好玩的，Google发行的NDK并不支持ARM架构

下载NDK#

Screenshot_2024-09-24-19-54-23-824_com.microsoft.emmx-edit.jpg 在Android开发者网站上下载NDK，下载地址为：https://developer.android.com/ndk/downloads 然后解压到root目录下

1
unzip android-ndk-r27b-linux.zip

然后安装zip工具链并新建一个test目录

1
pacman -S zip &&
2
mkdir test && cd test && touch test.sh

并填入以下内容

1
#!/bin/sh
2
set -eu

TEST_DIR="$(dirname "$(realpath "$0")")"

## ndk clang resource dir, get by command: <ndk_root>/toolchains/llvm/prebuilt/linux-x86_64/bin/clang --print-resource-dir

RESOURCE_DIR="${TEST_DIR}/../android-ndk-r27b/toolchains/llvm/prebuilt/linux-x86_64/lib/clang/18/"

在test目录下执行sh test.sh，会打印出以下日志

1
/bin/clang
