iphone OS 4用のライブラリを作成しようとしましたが、エラーが発生していました。
BerkeleyDBインストールガイドを参照したビルドスクリプトを次に示します。
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
ここで、3つの警告を含むエラーメッセージが表示されます。

スクリプトで間違っているところを教えてください。
前もって感謝します。
