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 ARMCCnINC

  • 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.
