如何在 XCode 4 的 i386 应用程序的 dylib 中使用 Sqlite？这种方法在 iPhone 应用程序中确实有效
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

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

我将链接到 SDK 中附带的 SQLite dylib，该库位于
/Developer/SDKs/MacOSX10.6.sdk/usr/lib/libsqlite3.dylib（根据需要替换您的目标 SDK）。I'd link against the SQLite dylib shipped in the SDK, which is at
/Developer/SDKs/MacOSX10.6.sdk/usr/lib/libsqlite3.dylib(substitute your target SDK as needed).
