一. ndk生成交叉编译工具链

请参考：Cargo+Ndk实现Android平台的rust源码交叉编译_u011376563的博客-CSDN博客

的3.1～3.2部分内容

二. 下载libfuse3.10.0源码

youthful@youthful-VirtualBox-Ubuntu:~/test$ git clone https://github.com/libfuse/libfuse.git

注意：本文编译的是3.10.0源码，libfuse源码可能已经更新版本，请下载之后切换到release 3.10.0版本。

三. 下载新版本meson编译工具

libfuse3.10.0默认使用meson+ninja编译源码，所以需要安装这2个编译工具。

meson需要使用0.54及以上版本，直接在github上下载即可：

youthful@youthful-VirtualBox-Ubuntu:~$ mkdir ~/work/meson/
youthful@youthful-VirtualBox-Ubuntu:~$ cd ~/work/meson/
youthful@youthful-VirtualBox-Ubuntu:~/work/meson$ git clone https://github.com/mesonbuild/meson.git

下载之后的meson是一个py脚本：~/work/meson/meson/meson.py，后续交叉编译需要使用该脚本工具。

四. 下载ninja编译工具

youthful@youthful-VirtualBox-Ubuntu:~/work/meson$ sudo apt install ninja-build

五. 修改libfuse源码及配置

5.1. 为meson添加交叉编译配置文件arm64.txt

在libfuse工程根目录创建arm64.txt，该文件用于配置交叉编译工具链及库路径：

[binaries]
c = '<your_toolchain_path_prefix>/bin/aarch64-linux-android30-clang'
cpp = '<your_toolchain_path_prefix>/bin/aarch64-linux-android30-clang++'
ar = '<your_toolchain_path_prefix>/bin/aarch64-linux-android-ar'
strip = '<your_toolchain_path_prefix>/bin/aarch64-linux-android-strip'
ld = '<your_toolchain_path_prefix>bin/aarch64-linux-android-ld.gold'

[properties]
skip_sanity_check = true
sys_root = '<your_toolchain_path_prefix>/sysroot'
c_args = ['-L<your_toolchain_path_prefix>/sysroot/usr/lib/aarch64-linux-android/30']

[host_machine]
system = 'linux'
cpu_family = 'aarch64'
cpu = 'aarch64'
endian = 'little'

[target_machine]
system = 'linux'
cpu_family = 'aarch64'
cpu = 'armv8a'
endian = 'little'

其中，

<your_toolchain_path_prefix>替换为你前面保存ndk生成的交叉工具链的目录，本文为：

/home/work/ndk_standalone_21.4.7075529/arm64

5.2. 修改源码及配置

1）删除example/meson.build，因为不需要示例

2）修改lib/fuse.c：

youthful@youthful-VirtualBox-Ubuntu:~/work/fuse/libfuse-3.10$ git diff lib/fuse.c
diff --git a/lib/fuse.c b/lib/fuse.c

3）修改lib/fuse_loop_mt.c：

六. 编译libfuse源码

youthful@youthful-VirtualBox-Ubuntu:~/work/fuse/libfuse-3.10$ ~/work/meson/meson/meson.py arm64-build --cross-file ./arm64.txt
youthful@youthful-VirtualBox-Ubuntu:~/work/fuse/libfuse-3.10$ ninja -C arm64-build

编译结果（<project_root>：libfuse源码根目录）：

<project_root>/arm64-build/lib/libfuse3.a（注：如果要编译so，请在5.4步骤修改lib/meson.build时，将library()字段放开，并注释掉static_library()字段！！！）

<project_root>/arm64-build/util/fusermount3

<project_root>/arm64-build/util/mount.fuse3
