precompiled-headers

If I don't include the stdafx even in an empty .cpp, I get this error fatal error C1010: unexpected end of file while looking for precompiled header. Did you forget to add '#include "StdAfx.h"' to your source? Why do I need to include it even in dummy files? If you use them, then you must include them. But you can turn them off in the project properties. However, the recommended way to use them is to "Force Include" the PCH from the command line , so that the file itself doesn't contain the PCH. That way the source file can be compatible with other systems. You can disable precompiled headers

OK, this is related to question "Constants in Objective C" . I created Constants.h and its corresponding Constants.m file: // Constants.h extern int const BOOKS; typedef enum SSDifficultyLevel { EASY = 0, MEDIUM = 1, HARD = 2 } SSDifficultyLevel; // Constants.m int const BOOKS = 66; My question: Is OK for the enum to be typedef 'd in Constants.h ? The code is compiling fine (no warnings or errors so far) but I was wondering if this is the right way to do it, as the solution provided in the related question involves splitting the constant's definition and declaration. Thanks. well, a constant

I'm having an issue using precompiled header files with MinGW. The compiler seems to find the precompiled header file but cc1plus.exe crashes immediately after (cc1plus.exe has stopped working). I've understood that this might be in connection with cc1plus.exe's low stack size, so I did the following to increase it: editbin cc1plus.exe /STACK 33554432 and I also tried to no avail: editbin cc1plus.exe /STACK 32768k This however did not solve it as it still keeps crashing whenever I try to compile my application. By the way I'm using the latest MinGw (gcc v 4.6.2) and the latest Eclipse CDT if

I'm using Boost Program Options , and it takes quite a while (10 seconds or even more) for compiling very small C++ code with it. It took 1 second compiling the code without boost library. Any idea how to boost compilation/link time with boost library? It's cross platform, so I need to compile the code with Mac OS X/Linux/PC. jalf There isn't really much you can do beyond the usual tricks: minimize dependencies: pull in only the Boost headers you really need, and use as specific headers as possible (many libraries have a single "master" header, such as boost/thread.hpp , but also a

I'm looking to create a precompiled header file, to avoid having to include the same debug and tracking libraries in every header in the project. I've created a file called -Prefix.pch: #ifdef __OBJC__ #import "Blah.h" #import "Blarg.h" #endif and added it to the project. Is there anything more I'm supposed to do, or should things just work now (assuming I do a project clean and recompile)? Set the target's build settings as follows: GCC_PRECOMPILE_PREFIX_HEADER=YES GCC_PREFIX_HEADER="Prefix.pch" Note that you can plop these keys in the Build Settings search field, if you prefer to use Xcode's
