How to install x11 in cent OS

Error: HGraf.c:118:77: error: X11/Xlib.h: No such file or directory

solution: https://ask.fedoraproject.org/en/question/27815/cant-compile-with-xlib/

If you're trying to determine what package has a header file, you can either run:

repoquery -qf /usr/include/X11/Xlib.h

(that will tell you what package has that file, you do need to know the full path, but it is usually pretty obvious)

Or, if you just want to install the package with that header file:

yum install /usr/include/X11/Xlib.h

Yum can do that because it has filelists_db in the extended repodata. :)

How to add header file in Visul stidio 2008

If you write in your code something like #include "FileWrite.h" you need to make sure compiler can find that file. There are three options:

• FileWrite.h should either be in the same directory as your source code file (.cpp) or
• Path to that header file should should be listed in project's Properties (in C/C++ -> General -> Additional Include Directories) or
• Path could be set in your VisualStudio - add it to Include Files in Tools->Options->Projects and Solutions->VC++ Directories

Which of these options shell be used depends on whether that header originates from this project (1st option) or some other project (any of other two options).
