precompiled-headers

This worked without error when this solution worked off of .lib files instead of .dll files. I have all of my projects except one currently using a precompiled header, without error . The precompiled header is called " LudoGlobal.h ". I am trying to link the last project to this precompiled header (which exists in a seperate, "Core", project) but I'm getting the following error: Error 4 fatal error C1083: Cannot open precompiled header file: '....\Output\LudoSound\Debug\LudoSound.pch': No such file or directory ludosoundmanager.cpp 1 for each .cpp file. Why is this? How can I solve it? I

Update: What are the effects of including stdafx.h in my header files? I started on a C++ project in Linux/Eclipse CDT and imported it into Visual C++/Windows. In Visual C++, I started using precompiled headers to speed up compilation and defined stdafx.cpp and stdafx.h. Here's my stdafx.h #pragma once #include <string> #include <vector> #include <map> ... and my stdafx.cpp #include "stdafx.h" In every .h and .cpp file, I have the following: #pragma once //if in a header file #include "stdafx.h" For both release and debug, I have "Create Precompiled Header (/Yc)". It compiled fine in debug

Back a long time ago I used to use pre-compiled headers: a. to speed compilation and b. because I supported multiple development tools like CodeWarrior, MPW, VS, ProjectBuilder, gcc, intel compilers, etc, etc. Now I have a Mac Pro with 32gb of RAM. Now I use just CMake. So do we really need pre-compiled headers any more? Are there obvious benefits that I just dont see/know? How can one make a cross-platform pre-compiled header? Maybe that would simplify my life too. There is no such thing as a build that is "Fast enough". Proponents of TDD ( Test-Driven Development ) will be upset if their

I have a huge project, something about 150 000 LOC of C++ code. Build time is something about 15 minutes. This project consists of many sub-projects of different sizes. I have built separate precompiled headers for each subproject, but when I use them build time stays roughly the same. It seemed that build time is 5-10% percent less, not more. Precompiled headers is definitely used, I use -Winvalid-pch option and I have tried to compile with -H compiler option, my precompiled headers appears in output with 'bang' symbol, that means that compiler is able to use precompiled header. All my

Short story: I can't make precompiled headers work properly with gcc -c option. Long story: Folks, I'm using gcc-4.4.1 on Linux and before trying precompiled headers in a really large project I decided to test them on simple program. They "kinda work" but I'm not happy with results and I'm sure there is something wrong about my setup. First of all, I wrote a simple program(main.cpp) to test if they work at all: #include <boost/bind.hpp> #include <boost/function.hpp> #include <boost/type_traits.hpp> int main() { return 0; } Then I created the precompiled headers file pre.h(in the same directory

I am using GCC precompiled headers in my project with multi-architecture build, but things break down when I try to place it in a directory different from current source's directory. The file is included with double quotes, and it works if I change it to angle brackets, but the problem is that I have a lot of other projects that use the same precompiled header name, so changing all of them to angle brackets is not desirable as it may create ambiguity about which header to include in Visual Studio build of the same files. GCC searches current directory for double-quote includes before its

This is my .pch file - // // Prefix header for all source files of the 'English Club' target in the 'English Club' project // #import <Availability.h> #ifndef __IPHONE_4_0 #warning "This project uses features only available in iOS SDK 4.0 and later." #endif #ifdef __OBJC__ #import <UIKit/UIKit.h> #import <Foundation/Foundation.h> #import <CoreData/CoreData.h> #import "Helper.h" #import "Animations.h" #import "Constants.h" #import "SoundPlayer.h" #import "UAirship.h" #import "UAStoreFront.h" #import "UIIMagesNames.h" #import "UIView+Sizes.h" #import "HelpButton.h" #import "SoundPlayer.h"
