错误：@令牌之前的语法错误(为什么？)
提问于 2009-08-04 23:35:53
我在我的混和项目中包含了iPhone sqlite代码，并删除了对iPhone sqlite框架的引用。
我的主要目标编译得很好。
我有第二个用google框架进行单元测试的目标。在编译时，我得到：
错误：@令牌之前的语法错误
我不明白为什么。我已经将这两个项目设置为sdk 2。
更新:我包括到sqlite代码& google的链接。我必须补充说，在我添加sqlite代码之前，目标编译的时间是很好的。我不会发布示例代码，因为我得到了1263个错误- -所以我在所有文件-中都出现了错误，但这是一个示例跟踪：

gcc命令行正在将.h文件编译为.gch文件。
/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.0
# ...
-x c-header -arch i386 -fmessage-length=0 -pipe -std=c99 -Wno-trigraphs # ...

# THE INPUT FILE:

SharedPrecompiledHeaders/UIKit-dqqtnrciylhdtjbmyglpcezxchmz/UIKit.h.gch也就是说，将UIKit.h转换为UIKit.h.gch：将头文件转换为“预编译的”头文件，该头文件可以更快地包含，因为它是标记化的形式。
看起来编译器不知道它应该预编译一个标头；它不知怎么配置不正确，只是把它当作要实际编译的代码，并且因为代码是目标C而窒息。
