用iOS SDK 4.2编译libpq
我正在尝试再次编译libpq for arm和i386以及iOS SDK 4.2。
我去年做了SDK3.x，没有任何问题。
现在，当我想用两个文件创build胖二进制文件，我得到这个错误：
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)) 我正在编译，因为我编译的文件不能用最新的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：

这适用于我的臂库，但我使用gcc 4.2，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
我的旧模拟器脚本不再工作了，它仍然工作正常的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 $ROOT_DIR/src/interfaces/libpq
更新
这是完整的脚本。 把bash脚本放到postgres目录下并构build。 在你的项目中包含$ POSTGRESDIR / src / include和$ POSTGRESDIR / src / interfaces / libpq来获取必要的头文件。 注意这适用于Postgres 8.没有在Postgres 9上testing过。

在github上有项目“libpq-ios”。 我用它。
