Hi,
This time Iam Struggling with C++,as Iam very new to this I have some start up difficulties also.In this project Iam using so many Header files and libraries.While building the application it is showing: fatal error C1083: Cannot open include file,but the file is already included.While searching with this error I came to know that if the path given is incorrect then also this error will come.So I checked that also.Everything Ok but again it is showing fatal error C1083: Cannot open include file.

Please suggest some help.

Below is my code:

And the showing missing file is "exinfo.h"

You need to give a little more information such as which file is failing to be included and where is the #include statement itself? What inclusion paths are set in your development environment? Then it may be possible to help.

And the showing missing file is "exinfo.h"

Matthew Faithfull 14-Mar-13 4:36am

OK all we need now is the actual path to "exinfo.h" on the disk and the set of search directories, in order, from your IDE or build environment.

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 14-Mar-13 4:21am

May be the files are present in C Directory, which is not accessible by Application.
So, move those files somewhere in other Directories like D or E and try.

danil33 14-Mar-13 4:29am

Yes the files were present in the C directory.So I shifted them to D directory again it is showing the same error.

Solution 2

Solution 1 is correct (see that one first). If that doesn't fix your problem however, you might have a infinite loop in your header includes. If you include header1.h, which includes header2.h, which includes header1.h again, the compiler gets upset. You can get indemnity from this with:
- ensuring you don't have include loops manually
- #pragma once
- header guard blocks.

You have to make sure the file is in the compiler search path. For instance with Visual Studio 2005, click on Tools->Options menu item, then select Projects And Solutions->VC++ Directories, choose Include Files in the list just below Show Directories For: label and finally add your include file folder.
