Compile OpenSSL for iOS

IOS: 5.1

OS: Lion 10.7.4

1) Compile arm6

Makedir arm6lib

./Configure BSD-generic32 -- prefix =/libs/OpenSSL -- openssldir =/libs/OpenSSL

Change the makefile

Cc =/applications/xcode. APP/contents/developer/platforms/iphoneos. Platform/developer/usr/bin/GCC-arch armv7
Cflag =-dopenssl_threads-pthread-d_thread_safe-d_reentrant-ddso_dlfcn-dhave_dlfcn_h-dtermios-O3-fomit-frame-pointer-wall-isysroot/applications/xcode. APP/contents/developer/platforms/iphoneos. platform/developer/sdks/iphoneos5.1.sdk

Make

Make install

Copy the arm6lib directory

 

Delete the openssl-0.9.8d directory because it is found that make clean does not really clear all, leave a lot of. O files directly in this environment to compile the ARM7 will generate errors

 

2) Compile the ARM7 program.

Compiling in the new environment is similar to that in arm6

Makedir arm7lib

./Configure BSD-generic32 -- prefix =/libs/OpenSSL -- openssldir =/libs/OpenSSL

Change the makefile

Cc =/applications/xcode. APP/contents/developer/platforms/iphoneos. Platform/developer/usr/bin/GCC-arch armv7
Cflag =-dopenssl_threads-pthread-d_thread_safe-d_reentrant-ddso_dlfcn-dhave_dlfcn_h-dtermios-O3-fomit-frame-pointer-wall-isysroot/applications/xcode. APP/contents/developer/platforms/iphoneos. platform/developer/sdks/iphoneos5.1.sdk

Make

Make install

Copy the arm7lib directory

3) connect to the universal lib

We copied arm6lib arm7lib to a directory to go to this directory.

Lipo-create./arm6lib/lib/libcrypto. A./arm7lib/lib/libcrypto. A-output./libcrypto.

Lipo-create./arm6lib/lib/libssl. A./arm7lib/lib/libssl. A-output./libssl.

Inspection result

Lipo-Info libssl.

Result:

Ubuntures In the FAT file: libssl. A are: armv6 armv7

Success

 

4) Simulator Compilation

Similar to the above, it is a little different when you modify makefile.
