问题描述

我试图再次编译libpq的arm和i386与iOS SDK 4.2。



我去年对于SDK3.x没有任何问题。 / p>

现在，当我想创建两个文件的胖二进制文件时，我收到此错误：



<$文件（/Users/montx/mylibs_sdk42/libpq.arm）的指定架构类型（arm）不匹配其cputype（7）和cpusubtype（3）（应为cputype（12））p $ p> 和cpusubtype（0））



我再次编译，因为我的编译文件不能使用最新的iOS4.2 

 检测到尝试调用iPhone中不存在的系统库中的符号：
 fcntl $ UNIX2003从图像GlobalScan中的函数pg_set_noblock调用。 
如果你遇到这个问题在gdb中运行一个模拟器二进制文件，请确保你'首先设置start-with-shell关闭'。

感谢！

解决方案

但我使用gcc 4.2和我的目标是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

我的旧脚本模拟器不工作了， 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 
  
 
 
 
 已更新 
 
 
 
这是完整的脚本。删除postgres目录中的bash脚本并生成。在您的项目中包含$ POSTGRESDIR / src / include和$ POSTGRESDIR / src / interfaces / libpq以获取标头必需。注意这适用于Postgres 8.没有在Postgres 9上测试它。
 ＃！/ bin / bash 
 set -e 
 
 if [-d./lib] 
 then 
 echo现有库已删除
 rm -rf lib / * 
 else 
 echo生成输出目录
 mkdir lib 
 fi 
 
如果[-e./src/Makefile.global] 
 then 
 make -C ./src/interfaces/libpq distclean 
 fi 
 
 chmod u + x ./configure 
 
 #Build i386库
 DEVROOT = / Developer / Platforms / iPhoneSimulator.platform / Developer 
 SDKROOT = $ DEVROOT / SDKs / iPhoneSimulator4.2.sdk

 LD = $ DEVROOT / usr / bin / ld 
 b $ b make -C ./src/interfaces/libpq

 LD = $ DEVROOT / usr / bin / ld

 cp ./src/interfaces/libpq/libpq.a lib / libpq.arm 
  
 
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

make -C src/interfaces/libpq
cp /Users/montx/Downloads/postgresql-8.4.1/src/interfaces/libpq/libpq.a /Users/montx/mylibs_sdk42/libpq.arm

#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



 解决方案 
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
