CyberGarage

Xcode 1.5 : I compiled existing Xcode projects such as CyberLink, but the following errors occurred.

gcc-3.3: CyberLink_Prefix.pch: No such file or directory

gcc-3.3: warning: `-x c++-header' after last input file has no effect

gcc-3.3: no input files

	gcc-3.3: CyberLink_Prefix.pch: No such file or directory

	gcc-3.3: warning: `-x c++-header' after last input file has no effect

	gcc-3.3: no input files

I checked the release notes of Xcode v1.5, and I find out the following change about the precompiled header

gcc 3.3 is the default compiler. gcc 3.3 offers the following advantages over gcc 3.1:

Support for optimized code generation for the new PowerPC G5 processor

Support for stub libraries

Many performance optimizations

A new precompiled header mechanism (PCH) that works for C, Objective-C, C++, and Objective-C++

Then, I added the following precompiled header to refer a new project that was created using Xcode v1.5, and I could compile the projects with no problem.

//

// Prefix header for all source files of the 'CyberLink' target in the 'CyberLink' project

//



#ifdef __OBJC__

    #import <Cocoa/Cocoa.h>

#endif
