newlib/configure.host

   1 # configure.host
   2
   3 # This shell script handles all host based configuration for newlib.
   4 # It sets various shell variables based on the the host and the
   5 # configuration options.  You can modify this shell script without
   6 # needing to rerun autoconf.
   7
   8 # This shell script should be invoked as
   9 #   . configure.host
  10 # If it encounters an error, it will exit with a message.
  11
  12 # FIXME: This script is too complicated.  It does things in too many
  13 # different ways.  This was taken from the old Cygnus configure script
  14 # with only minor changes.  It should be cleaned up.
  15
  16 # FIXME: The general approach of picking and choosing which
  17 # directories to configure, other than machine_dir and sys_dir, is
  18 # potentially confusing.

  20 # It uses the following shell variables:
  21 #   host                The configuration host
  22 #   host_cpu            The configuration host CPU
  23 #   newlib_mb           --enable-newlib-mb ("yes", "no")
  24 #   target_optspace     --enable-target-optspace ("yes", "no", "")
  25 #   newlib_multithread  --enable-newlib-multithread ("yes", "no", "yes")
  26 #   newlib_elix_level   --enable-newlib-elix-level ("1","2","3","4") ("4")

  32 #   machine_dir         Subdirectory of libc/machine to configure
  33 #   sys_dir             Subdirectory of libc/sys to configure
  34 #   have_sys_mach_dir   Is there a machine subdirectory in sys subdirectory
