I'm trying to compile again the libpq for arm and i386 with the iOS SDK 4.2.

I did last year for SDK3.x without any problems.

Now, when I want to create the fat binary file with two files, I'm getting this error:

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))

I'm compiling again because my compiled files doesn't work with the latest 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.

thanks!

Here is the full script:

#!/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

#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

There is project "libpq-ios" on github. I used it.

This works for me for the arm library but I'm using gcc 4.2 and I'm targeting 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

My old script for the simulator doesn't work anymore though, and it usto work fine again iOS 3.2. 

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

Updated

Here is the complete script. Drop the bash script in the postgres directory and build. In your project include $POSTGRESDIR/src/include and $POSTGRESDIR/src/interfaces/libpq to get the headers necessary. Note this works for Postgres 8. Haven't tested it on Postgres 9.

#!/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

#Build i386 library
DEVROOT=/Developer/Platforms/iPhoneSimulator.platform/Developer 
SDKROOT=$DEVROOT/SDKs/iPhoneSimulator4.2.sdk
