# Other materials:
Before configuring the configuration, let's first explain the meaning of the configuration to be used:
-- Target = the generated target system # You do not need to configure this for compiling hosts.
-- Build = type of the compiled machine # This can be said to have to be modified
-- Host = host type # this parameter is not required
-- Prefix = installed directory # This must be configured
-- Enable-languages ages = This is the program generated by the configuration. Which language of the compiler is supported? # This configuration is required to prevent many files from being generated. Too many parameters cause compilation failure
-- Disable-werror: this is a close reminder # Not necessarily required.
-- Enable-ld = [yes, no] this is used in binutils compilation. # If you only compile this GCC, this can be omitted.
-- Enable-gold = [yes, no] this is used in binutils compilation. # This is not required only for compiling GCC.
-- Program-suffix = This is the post-Order of the program # to distinguish it from the built-in gcc, we recommend that you add this
-- Program-transform-name = This is used to generate personalized gcc naming rules. # If you use this option, you do not need the -- program-suffix option above.
-- Disable-multilib disable cross-platform libraries # use this option for Building
