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

# Compiler settings
CC := gcc
CFLAGS := -g -O2 -std=c99 -D_XOPEN_SOURCE=600 -D_DEFAULT_SOURCE -D_GNU_SOURCE -Wall
LDFLAGS := 

# Libraries
LIBS := -levent_core
ifeq ($(DBG_BUILD),1)
    LIBS += -levent_extra
endif

# Sources and objects
SRCS := parser.c main.c redsocks.c log.c http-connect.c socks4.c socks5.c http-relay.c base.c base64.c md5.c http-auth.c utils.c redudp.c dnstc.c dnsu2t.c gen/version.c
OBJS := $(SRCS:.c=.o)
DEPS := .depend
OUT := redsocks
VERSION := 0.5
CONF := config.h

# Directories
GEN_DIR := gen

# Targets
.PHONY: all clean distclean test tags

# Default target
all: $(OUT)

# Generate version.c
gen/version.c: *.c *.h $(GEN_DIR)/.build
	rm -f $@.tmp
	echo '/* this file is auto-generated during build */' > $@.tmp
	echo '#include "../version.h"' >> $@.tmp
	echo 'const char* redsocks_version = ' >> $@.tmp
	if [ -d .git ]; then \
		echo '"redsocks.git/'`git describe --tags`'"'; \
		if [ `git status --porcelain | grep -v -c '^??'` != 0 ]; then \
			echo '"'"-unclean-$(shell date --rfc-3339=seconds | tr ' ' 'T')-$(USER)@$(shell uname -n)"'"'; \
		fi \
	else \
		echo '"redsocks/$(VERSION)"'; \
	fi >> $@.tmp
	echo ';' >> $@.tmp
	mv -f $@.tmp $@

# Create necessary directories
$(GEN_DIR)/.build:
	mkdir -p $(GEN_DIR)
	touch $@

# Dependency generation
$(DEPS): $(SRCS)
	$(CC) -MM $(SRCS) 2>/dev/null > $(DEPS) || \
	( \
		# Handle missing dependencies properly with correct formatting \
		for SRC in $(SRCS); do \
			echo -n "$${SRC%.c}.o: " >> $(DEPS); \
			# Collect includes for each source file \
			export SRC_DEPS="`sed '/^\#[ \t]*include \?"\(.*\)".*/!d;s//\1/' $$SRC | sort`"; \
			while true; do \
				export SRC_DEPS_OLD="$$SRC_DEPS"; \
				# Recursively collect dependencies \
				export SRC_DEPS="`echo $$SRC_DEPS | sed 's/  */\n/g' | sort`"; \
				test "$$SRC_DEPS" = "$$SRC_DEPS_OLD" && break; \
			done; \
			echo $$SRC $$SRC_DEPS >> $(DEPS); \
		done; \
	)

# Include dependencies
-include $(DEPS)

# Final executable
$(OUT): $(OBJS)
	$(CC) $(CFLAGS) -o $@ $^ $(LDFLAGS) $(LIBS)

# Clean the build
clean:
	$(RM) $(OUT) $(OBJS) $(CONF) $(DEPS)

# Clean everything, including generated files
distclean: clean
	$(RM) tags $(DEPS)
	$(RM) -r $(GEN_DIR)

# Create tags for code navigation
tags: *.c *.h
	ctags -R

# Run tests
test: tests/__build-tstamp__ tests/prlimit-nofile
	cd tests && env $(TEST_ENV) ./run

# Build tests
tests/__build-tstamp__: $(OUT) tests/[a-z]* tests/[a-z]*/*
	cd tests && ./build
	touch $@

# Build test for prlimit
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
