Mac电脑交叉编译iphone设备可以运行的redsocks, openssl, libsevent

准备：intel x86_64芯片的mac电脑，系统为mac os15.3.1，iphone为6s的ios14.4(rootful越狱)

第一步：准备工具链（推荐使用 theos + clang）

如果你已经安装过 Theos（或 NewTheos），直接用它内置的 clang 就能编译出 iOS Mach-O 可执行文件。

如果没有，可以这样安装：

# 安装 theos（推荐）
git clone --recursive https://github.com/theos/theos.git ~/theos

 

第二步：准备依赖库 libevent

你需要为 iOS 编译静态版本的 libevent：

git clone https://github.com/libevent/libevent.git
cd libevent
brew install autoconf automake libtool
./autogen.sh# 设置编译环境（假设你用 Xcode CLI 工具）
export SDK=$(xcrun --sdk iphoneos --show-sdk-path)
export CC="$(xcrun --sdk iphoneos -f clang)"
export CFLAGS="-isysroot $SDK -arch arm64 -miphoneos-version-min=10.0"./configure --host=arm-apple-darwin --disable-shared --enable-static
make

第三步：获取并修改 redsocks 源码

git clone https://github.com/darkk/redsocks.git
cd redsocks

       更新一下Makefile更是和mac系统

tests/prlimit-nofile: tests/prlimit-nofile.c$(CC) $(CFLAGS) -o $@ $^

第四步：交叉编译 redsocks

export SDK=$(xcrun --sdk iphoneos --show-sdk-path)
export CC="$(xcrun --sdk iphoneos -f clang)"
export CFLAGS="-isysroot $SDK -arch arm64 -miphoneos-version-min=10.0"
export LDFLAGS="-L/path/to/libevent/.libs"make

第五步：签名（越狱设备免验证也建议做）

brew install ldid
ldid -S redsocks

第六步：推送到 iPhone

scp redsocks root@<iphone-ip>:/usr/local/bin/
scp redsocks.conf root@<iphone-ip>:/etc/

第七步：启动测试

chmod +x /usr/local/bin/redsocks
/usr/local/bin/redsocks -c /etc/redsocks.conf

第八步：编译Openssl3.5.0（可选）

git clone https://github.com/x2on/OpenSSL-for-iPhone.git
cd OpenSSL-for-iPhone#您可以尝试在构建脚本中添加以下选项来禁用 Bitcode：export CFLAGS="-fno-bitcode"
export LDFLAGS="-fno-bitcode"./build-libssl.sh clean
./build-libssl.sh
