Openssl for ios

去官方下载最新的OpenSSL源代码，修改crypto/ui/ui_openssl.c 文件中

static volatile sig_atomic_t intr_signal;＝》static volatile int intr_signal;

1》编译i386库

在终端：

mkdir ssllibs
cd openssl-1.0.0d
mkdir openssl_armv6 openssl_armv7 openssl_i386
./configure BSD-generic32 --openssldir=/Users/<username>/openssl-1.0.0a/openssl_i386

修改makefile文件

找到 CC = gcc 修改为

CC= /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc -arch i386

在下一行的CFLAG ＝，增加-isysroot /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.2.sdk

make

make install

2》编译armv6库

mv openssl_i386 ../ssllibs
make clean
./configure BSD-generic32 --openssldir=/Users/<username>/openssl-1.0.0a/openssl_armv6

修改makefile文件
找到 CC = gcc 修改为

CC= /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc -arch armv6

在下一行的CFLAG ＝，增加-isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.0.sdk

make
make install
