使用 iOS SDK 4.2 编译 libpq

Question

我正在尝试使用 iOS SDK 4.2 再次为 arm 和 i386 编译 libpq。

我去年为 SDK3.x 做过，没有任何问题。

现在，当我想用​​两个文件创建胖二进制文件时，我收到了这个错误：

specifed architecture type (arm) for file (/Users/montx/mylibs_sdk42/libpq.arm) does not match its cputype (7) and cpusubtype (3) (should be cputype (12) and cpusubtype (0))

我正在重新编译，因为我编译的文件不适用于最新的 iOS4.2

Detected an attempt to call a symbol in system libraries that is not present on the iPhone:
fcntl$UNIX2003 called from function pg_set_noblock in image GlobalScan.
If you are encountering this problem running a simulator binary within gdb, make sure you 'set start-with-shell off' first.

谢谢！

这是完整的脚本：

#!/bin/bash

DEVROOT=/Developer/Platforms/iPhoneOS.platform/Developer
SDKROOT=$DEVROOT/SDKs/iPhoneOS4.2.sdk

rm -rf  /Users/montx/mylibs_sdk42
mkdir /Users/montx/mylibs_sdk42 #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/montx/Downloads/postgresql-8.4.1/src/interfaces/libpq/libpq.a /Users/montx/mylibs_sdk42/libpq.arm


#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



#Then build i386 library ==> the simulator is 32bits


CFLAGS="$(OTHER_CFLAGS) -mmacosx-version-min=10.5"
LDFLAGS="$(OTHER_LDFLAGS) -mmacosx-version-min=10.5"

make clean && ./configure CFLAGS="-arch i386 -isysroot /Developer/SDKs/MacOSX10.5.sdk -mmacosx-version-min=10.5" && make -C src/interfaces/libpq


cp src/interfaces/libpq/libpq.a  /Users/montx/mylibs_sdk42/libpq.i386

#Then make fat binary
$DEVROOT/usr/bin/lipo -arch armv6 /Users/montx/mylibs_sdk42/libpq.arm -arch i386 /Users/montx/mylibs_sdk42/libpq.i386 -create -output  /Users/montx/mylibs_sdk42/libpq

github上有项目“libpq-ios”。我用过。

这适用于 arm 库，但我使用的是 gcc 4.2，而且我的目标是 armv7

DEVROOT=/Developer/Platforms/iPhoneOS.platform/Developer
SDKROOT=$DEVROOT/SDKs/iPhoneOS4.2.sdk
./configure --host=arm-apple-darwin --without-readline --disable-ipv6 \
  CC="$DEVROOT/usr/bin/gcc" \
  CPPFLAGS="-I$SDKROOT/usr/lib/gcc/arm-apple-darwin10/4.2.1/include/ \
            -I$SDKROOT/usr/include/" \
  CFLAGS="$CPPFLAGS -arch armv7 -pipe -no-cpp-precomp -isysroot $SDKROOT" \
  CPP="$DEVROOT/usr/bin/cpp $CPPFLAGS" \
  LD=$DEVROOT/usr/bin/ld 
make -C src/interfaces/libpq 
cp src/interfaces/libpq/libpq.a lib/libpq.arm

虽然我的模拟器旧脚本不再工作，但它在 iOS 3.2 中再次正常工作。

DEVROOT=/Developer/Platforms/iPhoneSimulator.platform/Developer 
SDKROOT=$DEVROOT/SDKs/iPhoneSimulator4.2.sdk
$ROOT_DIR/configure --host=i386-apple-darwin  \
  CC="$DEVROOT/usr/bin/gcc" \
  CPPFLAGS="-I$SDKROOT/usr/lib/gcc/i686-apple-darwin10/4.2.1/include/ \
            -I$SDKROOT/usr/include/ -mmacosx-version-min=10.5" \
  CFLAGS="$CPPFLAGS -arch i386 -pipe -no-cpp-precomp -isysroot $SDKROOT \
          -mmacosx-version-min=10.5" \
  CPP="$DEVROOT/usr/bin/cpp $CPPFLAGS" \
  LD=$DEVROOT/usr/bin/ld

make -C $ROOT_DIR/src/interfaces/libpq

更新

这是完整的脚本。将 bash 脚本放入 postgres 目录并构建。在您的项目中包含 $POSTGRESDIR/src/include 和 $POSTGRESDIR/src/interfaces/libpq 以获取必要的标头。请注意，这适用于 Postgres 8。尚未在 Postgres 9 上测试过。

#!/bin/bash
set -e

if [ -d "./lib" ]
then
    echo "Existing libs deleted"
    rm -rf lib/*
else
    echo "Generating output directory"
    mkdir lib
fi

if [ -e "./src/Makefile.global" ]
then
    make -C ./src/interfaces/libpq distclean
fi

chmod u+x ./configure
