From: http://www.x2on.de/2010/02/01/tutorial-iphone-app-with-compiled-openssl-library/
|

|

This is a tutorial for using self-compiled builds of the OpenSSL-library on the iPhone. You can build apps with XCode and the official SDK from Apple with this. I also made a small example-app for using the libraries with XCode and the iPhone/iPhone-Simulator. You can also download the precompiled OpenSSL-library (0.9.8m-beta1).
|
|||
|
|
|
|||
|
|
Create OpenSSL Libary:
|
|||
|
|
|
|||
|
|
* Download OpenSSL Sourcecode
|
|||
|
|
* Build OpenSSL for i368 iPhoneSimulator:
|
|||
|
|
o cd openssl-0.9.8m
|
|||
|
|
mkdir openssl_arm
|
|||
|
|
mkdir openssl_i386
|
|||
|
|
./config --openssldir=/Users/
|
|||
|
|
|
|||
|
|
o Edit Makefile:
|
|||
|
|
+ Change CC = cc to:
|
|||
|
|
|
|||
|
|
CC= /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.0
|
|||
|
|
|
|||
|
|
+ Add as first item to CFLAG:
|
|||
|
|
|
|||
|
|
-isysroot /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.1.2.sdk
|
|||
|
|
|
|||
|
|
o Change in crypto/ui/ui_openssl.c
|
|||
|
|
|
|||
|
|
static volatile sig_atomic_t intr_signal;
|
|||
|
|
|
|||
|
|
to
|
|||
|
|
|
|||
|
|
static volatile int intr_signal;
|
|||
|
|
|
|||
|
|
for preventing building error
|
|||
|
|
o Build it:
|
|||
|
|
|
|||
|
|
make
|
|||
|
|
make install
|
|||
|
|
|
|||
|
|
o Your libcrypto.a and libssl.a are in the folder openssl_i368/lib
|
|||
|
|
o Rename the two files to libcrypto_i386.a and libssl_i386.a
|
|||
|
|
* Build OpenSSL for arm iPhoneOS:
|
|||
|
|
o Edit Makefile:
|
|||
|
|
+ Search and replace openssl_i386 with openssl_arm
|
|||
|
|
+ Change -arch i386 in CFLAG to:
|
|||
|
|
-arch armv6
|
|||
|
|
+ Change

|
|
|||
|
|
CC= /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.0
|
|||
|
|
|
|||
|
|
+ Change
|
|||
|
|
|
|||
|
|
-isysroot /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.1.2.sdk
|
|||
|
|
|
|||
|
|
to
|
|||
|
|
|
|||
|
|
-isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.2.sdk
|
|||
|
|
|
|||
|
|
o Build it:
|
|||
|
|
make
|
|||
|
|
make install
|
|||
|
|
|
|||
|
|
o Your libcrypto.a and libssl.a are in the folder openssl_arm/lib
|
|||
|
|
o Rename the two files to libcrypto_arm.a and libssl_arm.a
|
|||
|
|
|
|||
|
|
Edit your iPhone-XCode project:
|
|||
|
|
|
|||
|
|
* Copy the “include” folder from OpenSSL into your project-folder
|
|||
|
|
* Copy the libcrypto_*.a and libss_*.a files into your project-folder
|
|||
|
|
* Drag the libcrypto_*.a and libss_*.a files into your XCode Framework Folder-Tree
|
|||
|
|
* Open the Build-Info from your “Target” (Righclick on Target – Get Info)
|
|||
|
|
* Change Library Search Paths to
|
|||
|
|
|
|||
|
|
$(inherited) "$(SRCROOT)"
|
|||
|
|
|
|||
|
|
* Change User Header Search Paths to include
|
|||
|
|
* Activate Always Search User Paths
|
|||
|
|
|
|||
|
|
Enjoy OpenSSL on the iPhone!

I have made an iPhone OS 3.1.2 XCode Project with OpenSSL 0.9.8m (Beta1) Libaries. The examples uses the MD5-algorithm to calculate an md5 hash from an UITextfield.
