xcode – 使用Libpq将iPhone App连接到PostgreSQL

我正在为arm和x86_84构建libpq. arm构建适用于真正的iPhone,x86_64适用于iPhone模拟器.然后我创建一个包含两个文件的胖二进制文件,最后得到一个名为libpq的文件.这个文件是我在常规Mac应用程序中使用的文件,它工作正常,并在尝试构建iPhone应用程序时导致问题.

这是我构建libpq时的构建脚本.

#!/bin/bash

DEVROOT=/Developer/Platforms/iPhoneOs.platform/Developer
SDKROOT=$DEVROOT/SDKs/iPhoneOS3.0.sdk

rm -rf  /Users/bob/mylibs
mkdir /Users/bob/mylibs #Store there compiled libs
make clean

#Build ARM library
./configure --host=arm-apple-darwin --without-readline --disable-ipv6 CC=$DEVROOT/usr/bin/arm-apple-darwin9-gcc-4.0.1 CPPFLAGS="-I$SDKROOT/usr/lib/gcc/arm-apple-darwin9/4.0.1/include/ -I$SDKROOT/usr/include/" CFLAGS="$CPPFLAGS -arch armv6 -pipe -no-cpp-precomp -isysroot $SDKROOT" CPP="$DEVROOT/usr/bin/cpp $CPPFLAGS" LD=$DEVROOT/usr/bin/ld
make -C src/interfaces/libpq
cp /Users/bob/Downloads/POSTGResql-8.4.1/src/interfaces/libpq/libpq.a /Users/bob/mylibs/libpq.arm

#Then build i386 library
make clean && ./configure  && make -C src/interfaces/libpq
cp src/interfaces/libpq/libpq.a  /Users/bob/mylibs/libpq.i386

#Then make fat binary
$DEVROOT/usr/bin/lipo -arch armv6 /Users/bob/mylibs/libpq.arm -arch x86_64 /Users/bob/mylibs/libpq.i386 -create -output  /Users/bob/mylibs/libpq

当我尝试从Xcode中编译iPhone应用程序时,这是构建日志.

遇到这种情况的其他人可以提供帮助吗？
