syntax error before "AT_NAME" token

某平台项目，同时支持3.x以及4.x iPhone OS，在Xcode 3.2.4下可以编译成功的程序，在Xcode 3.1.4下编译报错: syntax error before "AT_NAME" token

解决方法:

I've traced this problem to be the compiler version being used. From what I can tell, [REDACTED] requires GCC 4.2 while iPhone SDK 2.x only works with GCC 4.0.

Here's a way to fix this.

In your Target Info, select Build separator and look for the section Compiler Version. Then:

Select the C/C++ Compiler Version row
Set the default to GCC 4.0
At the bottom-left control, hit Add Build Setting Condition
On the left, choose Device - iPhone OS 3.0
On the right, chose GCC 4.2

Repeat steps 3 to 5, now with Simulator - iPhone OS 3.0 on step 4.

或者其它的解决 方法

The problem comes from SDK 3.0 which now use gcc 4.2 but scan-build still use /usr/bin/gcc. So you need to tell scan-build to use /usr/bin/gcc-4.2 instead.

scan-build --use-cc=/usr/bin/gcc-4.2 xcodebuild -configuration Debug
