How do I include header files from a specific directory in my GCC compilation command?

Including Header Files in GCC Search Path

When working with a project involving multiple files and headers spread across different folders, integrating them into the GCC search path is crucial. One such scenario arises when encountering code stored in various directories under "/home/me/development/skia."

To address this challenge, GCC provides the "-I" flag, which allows specifying additional search directories for header files. By adding "-I/home/me/development/skia" to the compilation command, GCC will automatically search for the necessary header files within that path.

For instance, to compile a sample code snippet that includes headers from different subdirectories of "skia," use the following command:

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

This will instruct GCC to search for the required headers, such as "SkCanvas.h," "SkDevice.h," and others, within the specified path. By including these headers, the code can access their declarations and definitions, enabling the compilation to succeed.
