Question

In netbeans I am creating a new folder and adding header files to it.

Now when I include the header file within the newly created folder to another file by using:

#include "folder1/myheaderFile.h"

The compiler complains that it is unable to find the header file.

The error is:

main.cpp:31:39: fatal error: folder1/myheaderFile.h: No such file or directory

Is there some way out as I want to include the header files within a folder in my #include?

EDIT: Do i need to make a makefile for every folder?
Another EDIT:

When I right clicked on the error its showing
unresolved directive
#include
Analyzed system include paths:
/usr/include/C++/4.6
/usr/include/C++/4.6/x84_64_linux_gnu
/usr/include/C++/4.6/backward

/usr/local/include
/usr/lib/gcc/x86_64-linux-gnu
/usr/include

Here’s for your convenience:

The include file paths you have specified are for system-wide headers. Is the header you are including yours or downloaded/installed system-wide? Do you see the path of the header in the output?
If you are including the header which is in a folder, from another folder, then you need to traverse back, i.e: #include "../folder/header.h"

If this is a system folder, such as the ones residing in /usr/local/include in my system, all you have to do is

#include <header.h>

or if it resides in a sub-folder (quite often),

#include <Libname/header.h>

As long as you have set the include paths pointing at it, it should work.

To setup the include paths and directories, see example: http://zetcode.com/articles/netbeanscdevelopment/ near the end of the page.

Remember that when you hardcode paths, you need to take into consideration the current path of the file which is including the header.

Alternatively, you can use cmake & make (don’t know what Netbeans uses), where you define everything your self.

You can test with full path, i.e:

#include "/home/user/project/folder/header.h

or you can test from command line and set the include path.

Hope it helps 🙂
