How to Include Header Files from Multiple Folders in the GCC Search Path?

Including Header Files in GCC Search Path

When working with complex codebases that span multiple folders, it becomes necessary to add the appropriate search paths to your compiler to locate necessary header files. In this case, GCC can be used to include header files from various folders within a specified path.

To resolve the issue mentioned in the question, where headers are located in different folders within the "/home/me/development/skia" directory, the following steps can be taken:

Solution:

1. Navigate to the directory containing the sample file as well as the necessary header files.
2. Issue the following command to instruct GCC to search for headers within the specified path:

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

In this command:

• gcc is the GNU Compiler Collection command.
• -c compiles the code without linking.
• -I specifies the include directory path where GCC will search for header files. In this case, it is set to "/home/me/development/skia".
• sample.c is the name of the sample file containing the headers to be included.

By following these steps, GCC will be able to locate and include the necessary header files from the specified path during the compilation process.
