How do I add a directory to the GCC header file search path?

Including Header Files in GCC Search Path

In GCC, header files are included in the search path to allow the compiler to locate and include them during compilation. This is particularly useful when header files are located in different folders within a project.

To include header files in the GCC search path, use the -I option followed by the path to the header file's directory. For example:

Consider the following code:

<code class="c">#include "SkCanvas.h"
#include "SkDevice.h"
#include "SkGLCanvas.h"
#include "SkGraphics.h"
#include "SkImageEncoder.h"
#include "SkPaint.h"
#include "SkPicture.h"
#include "SkStream.h"
#include "SkWindow.h"</code>

If these header files are located in various folders within /home/me/development/skia, to make GCC recognize this path, use the following command:

gcc -c -I/home/me/development/skia sample.c

This will add the /home/me/development/skia directory to the search path, allowing GCC to locate the header files when compiling the sample.c file.
