fatal error C1083 Cannot open include file xyz h No such file or directory

Question

I am using visual studio 2005 to create a project. And I have folder structure in project as: a folder called code. this folder contains all *.cxx files.

Now, I have created a class xyz in header file xyz.h. And defined every thing in xyz.cxx which is placed in code folder. But now when I try to compile it with visual studio it throws me an error "fatal error C1083: Cannot open include file: 'xyz.h': No such file or directory". how to rectify this problem.

Either move the xyz h file somewhere else so the preprocessor can find it  or else change the  include statement so the preprocessor finds it where it already is   Where the preprocessor looks for included files is described here   One solution is to put the xyz h file in a folder where the preprocessor is going to find it while following that search pattern   Alternatively you can change the  include statement so that the preprocessor can find it   You tell us the xyz cxx file is is in the  code  folder but you don t tell us where you ve put the xyz h file   Let s say your file structure looks like this      lt some folder gt  xyz h  lt some folder gt  code xyz cxx   In that case the  include statement in xyz cxx should look something like this      include     xyz h    On the other hand let s say your file structure looks like this      lt some folder gt  include xyz h  lt some folder gt  code xyz cxx   In that case the  include statement in xyz cxx should look something like this      include     include xyz h    Update  On the other other hand as  In silico points out in the comments  if you are using  include  lt xyz h gt  you should probably change it to  include  xyz h

The following approach helped me   Steps    1 Go to the corresponding directory where the header file that is missing is located   In my case    include unicode coll h was missing  and copy the directory location where the header file is located  Copy till the include directory    2 Right click on your project in the Solution Explorer- Properties- Configuration Properties- VC   Directories- Include Directories   Paste the copied path here   3 This solved my problem I hope this helps

I ran into this error in a different situation  posting the resolution for those arriving via search  from within Visual Studio  I had copied a file from one project and pasted into another  Turns out that creates a symbolic link  not an actual copy  Thus the project did not find the file in the current working directory as expected  When I made a physical copy instead  in Windows Explorer  suddenly  include  myfile h  worked
