Factors influencing how the compiler searches for header files

Several factors influence how the compiler searches for #include header files and source files.

  • The value of the environment variable ARMCC5INC.

  • The value of the environment variable ARMINC.

  • The -I and -J compiler options.

  • The --kandr_include and --sys_include compiler options.

  • Whether the filename is an absolute filename or a relative filename.

  • Whether the filename is between angle brackets or double quotes.
