Question

我使用xcode和libsqlite3.dylib for sqlite，但是当我编译到设备时出现以下错误：

ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

但是项目成功编译到模拟器，当我将项目编译到真实设备时发生错误。

Answer 1

查看是否已将libsqlite3.dylib添加到所有目标。

Answer 2

最后我发现了问题：libsqlite3.dylib，我使用的编译为armv6而不是7，所以我只需下载xcode dmg文件4.3并从中提取lib。

Answer 3

对于那些在Xcode 4.5.1中验证应用程序存档时收到此消息的人 - 存在一个已知问题，即Xcode无法正确处理包含非字母字符的产品名称。也就是说，在取出Product Name构建设置的所有非字母字符之后，问题就消失了。

缺少必需的架构armv7
