Berkeley DB for iPhone

我曾嘗試爲iphone OS 4創建庫，但出現錯誤。Berkeley DB for iPhone

以下是參考Berkeley DB安裝指南的構建腳本。

export DEV_iOS=/Developer/Platforms/iPhoneOS.platform/Developer 
export SDK_iOS=${DEV_iOS}/SDKs/iPhoneOS4.2.sdk 
export COMPILER_iOS=${DEV_iOS}/usr/bin 
export CC=${COMPILER_iOS}/gcc 
export CXX=${COMPILER_iOS}/g++ 
export LDFLAGS="-arch armv6 -pipe -Os -gdwarf-2 -no-cpp-precomp -mthumb -isysroot ${SDK_iOS}" 
export CFFLAGS=${LDFLAGS} 
export CXXFLAGS=${LDFLAGS} 
../dist/configure --host=arm-apple-darwin10 --with-cryptography=no --enable-shared=no 
make

在這裏，我收到錯誤消息with3警告：

libtool: link: /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc -O3 -o db_archive -arch armv6 -pipe -Os -gdwarf-2 -no-cpp-precomp -mthumb -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk db_archive.o util_sig.o libdb-5.1.a -lpthread

make: *** [db_archive] Error 1

請指引我，我哪裏做錯了的腳本。

在此先感謝。
