iphone - xcode sqlite3 libsqlite.dylib

Question

我的项目出现错误，但我不知道问题所在。这是我编译后的错误。

ld警告:

in /install/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/usr/lib/libsqlite3.dylib, file is not of required architecture

ld警告:

in /install/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/usr/lib/libsqlite3.0.dylib, file is not of required architecture Undefined symbols:"_sqlite3_open", referenced from: -[LiteSqlViewController openDB] in LiteSqlViewController.o "_sqlite3_close", referenced from: -[LiteSqlViewController openDB] in LiteSqlViewController.o

ld:

symbol(s) not found collect2: ld returned 1 exit status _sqlite3_open", referenced from:-[LiteSqlViewController openDB] in LiteSqlViewController.o "_sqlite3_close", referenced from:-[LiteSqlViewController openDB] in LiteSqlViewController.o

ld:

symbol(s) not found collect2: ld returned 1 exit status Build failed (2 errors)

我使用 OSX 10.5.8 xcode 3.1.2 iphone 模拟器 2.2.1 架构 PPC

命令结果:

file /usr/lib/libsqlite3.dylib : /usr/lib/libsqlite3.dylib: Mach-O universal binary with 4 architectures /usr/lib/libsqlite3.dylib (for architecture ppc7400): Mach-O dynamically linked shared library ppc /usr/lib/libsqlite3.dylib (for architecture ppc64): Mach-O 64-bit dynamically linked shared library ppc64 /usr/lib/libsqlite3.dylib (for architecture i386): Mach-O dynamically linked shared library i386 /usr/lib/libsqlite3.dylib (for architecture x86_64): Mach-O 64-bit dynamically linked shared library x86_64.

在 PPC Mac 上使用 iPhone 模拟器似乎不太简单。使用您收到的第一个错误中的路径发出命令 file(就在第一个 ld 警告:之后)。查看this related question ，也许这些步骤有帮助。

旧答案:

您是否在项目中链接了libsqlite3.dylib？

在 Xcode 4 中，可以像屏幕截图中所示那样完成:按加号并添加 libsqlite3.dylib。然后，您可以将库拖到 Linked Frameworks 文件夹中。 (屏幕截图显示的是 Mac OS X 应用程序，iOS 应用程序也是如此。)
