為ios編譯openssl

ios版本：5.1

os:lion 10.7.4

1）編譯arm6

makedir arm6lib

./configure BSD-generic32 --prefix=/libs/openssl --openssldir=/libs/openssl

變更檔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

將arm6lib 目錄複寫出來

 

刪除openssl-0.9.8d目錄因為發現make clean並不是真的全部清除，留有很多.o檔案 直接在這個在環境中編譯arm7的會產生錯誤

 

2) 編譯arm7

在新的環境中編譯和arm6的類似6

 makedir arm7lib

./configure BSD-generic32 --prefix=/libs/openssl --openssldir=/libs/openssl

變更檔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

將arm7lib 目錄複寫出來

3）串連為universal lib

前面我們將arm6lib arm7lib複製到一個目錄，進入這個目錄

lipo -create ./arm6lib/lib/libcrypto.a  ./arm7lib/lib/libcrypto.a  -output ./libcrypto.a

lipo -create ./arm6lib/lib/libssl.a  ./arm7lib/lib/libssl.a  -output ./libssl.a

檢驗結果

lipo -info libssl.a 

結果為：

   Architectures in the fat file: libssl.a are: armv6 armv7 

表示成功

 

4)模擬器編譯

與上面類似，只是修改Makefile時有點不同

CC=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc -arch i386
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/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.1.sdk
