# configure.host
|
|
|
|
# This shell script handles all host based configuration for newlib.
|
|
# It sets various shell variables based on the the host and the
|
|
# configuration options. You can modify this shell script without
|
|
# needing to rerun autoconf.
|
|
|
|
# This shell script should be invoked as
|
|
# . configure.host
|
|
# If it encounters an error, it will exit with a message.
|
|
|
|
# FIXME: This script is too complicated. It does things in too many
|
|
# different ways. This was taken from the old Cygnus configure script
|
|
# with only minor changes. It should be cleaned up.
|
|
|
|
# FIXME: The general approach of picking and choosing which
|
|
# directories to configure, other than machine_dir and sys_dir, is
|
|
# potentially confusing.
|
|
|
|
# It uses the following shell variables:
|
|
# host The configuration host
|
|
# host_cpu The configuration host CPU
|
|
# newlib_mb --enable-newlib-mb ("yes", "no")
|
|
# target_optspace --enable-target-optspace ("yes", "no", "")

# newlib_multithread --enable-newlib-multithread ("yes", "no", "yes")

# newlib_elix_level --enable-newlib-elix-level ("1","2","3","4") ("4")
|
|
# newlib_io_c99_formats --enable-newlib-io-c99-formats ("yes", "no", "")
|
|
# newlib_io_long_long --enable-newlib-io-long-long ("yes", "no", "")
|

# newlib_io_long_double --enable-newlib-io-long-double ("yes", "no", "")

# newlib_fno_builtin --disable-newlib-fno-builtin ("yes", "no, "")
|
|

# newlib_cflags Special CFLAGS to use when building
|
|
# machine_dir Subdirectory of libc/machine to configure
|
|
# sys_dir Subdirectory of libc/sys to configure
