OpenSSL Library with iOS 4.2

Create OpenSSL Libary:

• Download OpenSSL Sourcecode
• Build OpenSSL for i368 iPhoneSimulator:

  • cd openssl-1.0.0c
    mkdir openssl_arm
    mkdir openssl_i386
    ./config --openssldir=/Users/<username>/openssl-1.0.0c/openssl_i386

  • Edit Makefile:
    • Change CC = cc to:

      CC= /Developer/usr/bin/gcc-4.2

    • Add as first item to CFLAG:

      -isysroot /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.2.sdk

  • Change in crypto/ui/ui_openssl.c

    static volatile sig_atomic_t intr_signal;

    to
    

    static volatile int intr_signal;

    for preventing building error
  • Build it:

    make
    make install

  • Your libcrypto.a and libssl.a are in the folder openssl_i368/lib
  • Rename the two files to libcrypto_i386.a and libssl_i386.a
• Build OpenSSL for arm iPhoneOS:

  • mv openssl_i386 openssl_i386_lib
    make clean

  • Edit Makefile:
    • Search and replace openssl_i386 with openssl_arm
    • Change -arch i386 in CFLAG to:
      -arch armv6
    • Change

      CC=  /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.2

      to
      

      CC=  /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2

    • Change

      -isysroot  /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.2.sdk

      to
      

      -isysroot  /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk

  • Build it:

    make
    make install

  • Your libcrypto.a and libssl.a are in the folder openssl_armv6/lib
  • Rename the two files to libcrypto_armv6.a and libssl_armv6.a
• 
  
• Build OpenSSL for armv7 iPhoneOS:

  • mv openssl_armv6 openssl_armv6_lib
    make clean

  • Edit Makefile:
    • Search and replace openssl_armv6 with openssl_armv7
    • Change -arch armv6 in CFLAG to:
      -arch armv7
  • Build it:

    make
    make install

  • Your libcrypto.a and libssl.a are in the folder openssl_armv7/lib
  • Rename the two files to libcrypto_armv7.a and libssl_armv7.a
