Visual Studio Precompiled Header Error


If the module is loaded at a different address in subsequent compilations, the VFTP’s in the PCH will be inaccurate.

That’s a long-winded way of saying “both the This issue may relate to the *.pch file. Otherwise you are guaranteed to get compilation errors. It is logical to create two precompiled headers, and use them in different parts of the program. have a peek here

The amount of work the preprocessor has to do during project compilation can be greatly reduced. I don't know how exactly it is all implemented in Visual C++, but I know that, for instance, you can store text already split into lexemes. It enforces that you include the precompiled header file in each source file, but it will happily ignore includes, defines, and other code before that include.

Phaeron, which OS versions are you switching between? It looks like the damage that EMET does is like herpes. For me, the sanest approach was: download and install EMET fromhere use EMET to disable "MandatoryASLR" and "BottomUpASLR" on the C compiler (cl.exe) This leaves you with ASLR enabled for everything /analyze Compiler Option {{offlineMessage}} Store Store home Devices Microsoft Surface PCs & tablets Xbox Virtual reality Accessories Windows phone Software Office Windows Additional software Apps All apps Windows apps Windows phone apps Games Xbox

Kb976656 The defaults are dangerous For some projects - typically non-MFC projects, but the specifics depend on what version of VC++ you are using - the project wizard's set the precompiled header For example, below is the stdafx.h file we use in PVS-Studio (the text is abridged for the article): #include "VivaCore/VivaPortSupport.h" //For /Wall #pragma warning(push) #pragma warning(disable : 4820) #pragma warning(disable : On a project that pays attention to physical design it is typically possible to rebuild after modifying a header file in "constant time" - one or two source files recompile, and

This was insufficient in Win7 as randomization became more aggressive.

Our first attempt to fix the problem involved setting the preferred base address of each compiler module to Disable The /analyze Compiler Option If It Is Enabled.

That leads us to this suggestion... navigate here Include only those files that change very, very rarely. They will then dump out build times for each part of your build.

Troubles occur when programmers start using files from one project in another.

Sure, it's a bit messier, and if your source file ends up being 10,000 lines long it may be completely unmanageable. Note, this has no impact on the output of the compiler - your programs will still be ASLR-enabled or not, depending on what switches you pass on the command line. PROFIT! Possible solutions: Disable precompiled headers for all the C-files.

For all the gory details, read this MSDN article - Two Choices for Precompiling Code. The basic idea is that one cpp file is specified as creating the precompiled header file and the other cpp files uses that precompiled header file. Set "$(IntDir)$(TargetName).pch" for the "Precompiled Header Output File" option. Practice makes perfect.

This hotfix might receive additional testing.
