在 XCode 4 For iOS 的 i386 应用程序的 dylib 中使用 Sqlite

我需要从目录添加一个名为 libsqlite3.0.dylib 的文件： /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148)/Symbols/usr/lib/

我有一种从 sqlite DB 列获取 MaxID 的方法。这在我制作的通用 iOS 应用程序中运行良好。我想移植这段代码转到 Mac 应用程序 i386。

因为我找不到 i386 这样的 dylib，所以我使用下载文件：sqlite-autoconf-3070500.tar.gz

按照指示我在 /usr/local/lib

libsqlite3.a 中生成了 3 个文件 libsqlite3.la libsqlite3.dylib

在 XCode 中我已将 '/usr/local/lib' 添加到构建设置->搜索路径->

我使用的库搜索路径：导出 DYLD_LIBRARY_PATH=/usr/local/bin/:$DYLD_LIBRARY_PATH

当我取消注释时，出现以下构建错误中的 sqlite 代码

AppDelegate.m Ld /Users/appleuser/Library/Developer/Xcode/DerivedData/iHungryMacNonDoc-dakfnxxiwzxehygtwrboebgysgwc/Build/Products/Debug/iHungryMacNonDoc.app/Contents/MacOS/iHungryMacNonDoc 正常 i386 cd /Users/appleuser/Cocoa/iHungryMacNonDoc setenv MACOSX_DEPLOYMENT_TARGET 10.6 /Developer/usr/bin/llvm-gcc-4.2 -arch i386 -isysroot /Developer/SDKs/MacOSX10.6.sdk -L/Users/appleuser/Library/Developer/Xcode/DerivedData/iHungryMacNonDoc-dakfnxxiwzxehygtwrboebgysgwc/Build/Products/调试 -L/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.3.sdk/usr/lib -L/Users/appleuser/Cocoa/iHungryMacNonDoc/../SqliteLib -L/Developer/Platforms/iPhoneSimulator.platform /Developer/SDKs/iPhoneSimulator4.3.sdk/usr/lib -F/Users/appleuser/Library/Developer/Xcode/DerivedData/iHungryMacNonDoc-dakfnxxiwzxehygtwrboebgysgwc/Build/Products/Debug -filelist /Users/appleuser/Library/Developer/Xcode /DerivedData/iHungryMacNonDoc-dakfnxxiwzxehygtwrboebgysgwc/Build/Intermediates/iHungryMacNonDoc.build/Debug/iHungryMacNonDoc.build/Objects-normal/i386/iHungryMacNonDoc.LinkFileList -mmacosx-version-min=10.6 -framework Cocoa -lsqlite3.0.8.6 -o / Users/appleuser/Library/Developer/Xcode/DerivedData/iHungryMacNonDoc-dakfnxxiwzxehygtwrboebgysgwc/Build/Products/Debug/iHungryMacNonDoc.app/Contents/MacOS/iHungryMacNonDoc

AppDelegate.h 开始 ////////////

导入“AppDelegate.h”

导入“IngredXML.h”

导入“XmlListReader.h”

导入“Constants.h”

导入

导入“/usr/include/sqlite3.h”

谢谢读完这篇文章就这么多了。请指教。标记

Using Sqlite in a dylib in an i386 app in XCode 4

For iOS I needed to add a file namely libsqlite3.0.dylib from directory:
/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148)/Symbols/usr/lib/

I have a method that obtains and MaxID from a column of an sqlite DB.
This works fine in a universal iOS app I made. I want to port this code
over to a Mac app i386.

Because I could not find such an dylib for i386, I created one using
the download file: sqlite-autoconf-3070500.tar.gz

Following directions I produced 3 files in /usr/local/lib

libsqlite3.a
libsqlite3.la
libsqlite3.dylib

In XCode I have add '/usr/local/lib' to the
Build Setting->Search Paths->Library Search Paths

I have used:
export DYLD_LIBRARY_PATH=/usr/local/bin/:$DYLD_LIBRARY_PATH

I get the following build error when I uncomment the
sqlite code in AppDelegate.m
