Sometimes, Visual c++ users see a pretty confusing error message when they compile or build their projects. the error message says :
fatal error C1083: Cannot open precompiled header file: 'filename.pch': No such file or directory
my solution was :
In VS, go to Project->Options, set the Configuration Combobox in top to 'All Configurations', and then from left pan, choose 'C/C++->Precompiled Haeders' and set 'Create/Use Precompiled headers' option to value : 'Create Precompiled headers (/Yc)'.
which turned out not to be an accurate solution (Read the Messages below).
well, here is the solution :
1) Right click on the PROJECT (in Solution Explorer) | Properties | C/C++ | Pre-compiled Headers... here you set to ** /Yu **
2) Right click on STDAFX.CPP (in Solution Explorer) | Properties | C/C++ | Pre-compiled Headers... here you set to ** /Yc **
