################################################################################
## This file is a shell script fragment that supplies the information
## necessary to tailor a template configure script into the configure
## script appropriate for this directory. For more information, check
## any existing configure script.
## Be warned, there are two types of configure.in files. There are those
## used by Autoconf, which are macros which are expanded into a configure
## script by autoconf. The other sort, of which this is one, is executed
## by Cygnus configure.
## For more information on these two systems, check out the documentation
## for 'Autoconf' (autoconf.texi) and 'Configure' (configure.texi).
################################################################################
### To add a new directory to the tree, first choose whether it is a target
### or a host dependent tool. Then put it into the appropriate list
### (library or tools, host or target), doing a dependency sort. For
### example, gdb requires that byacc (or bison) be built first, so it is in
### the ${host_tools} list after byacc and bison.
# these libraries are used by various programs built for the host environment
#
host_libs="mmalloc libiberty opcodes bfd readline glob tcl tk"
# these tools are built for the host environment
#
host_tools="texinfo byacc flex bison binutils ld gas gcc gdb make patch
send_pr gprof gdbtest tgas etc expect deja-gnu z8ksim
m4 autoconf ispell grep diff rcs cvs fileutils shellutils
textutils wdiff find emacs"
# these libraries are built for the target environment, and are built after the host
# libraries and the host tools (which may be a cross compiler)
#
target_libs="libm xiberty newlib libg++"
# these tools are built using the target libs, and are intended to run only in the
# target environment. we currently have none
#
target_tools=
################################################################################
## These two lists are of directories that are to be removed from the
## ${configdirs} list for either cross-compilations or for native-
## compilations. For example, it doesn't make that much sense to
## cross-compile Emacs, nor is it terribly useful to compile xiberty in
## a native environment.
# directories to be built in the native environment only
#
native_only="m4 autoconf ispell grep diff rcs cvs sed fileutils shellutils textutils wdiff find emacs"
# directories to be built in the target environment only
#
cross_only="xiberty newlib"
## All tools belong in one of the four categories, and are assigned above
#
configdirs="${host_libs} ${host_tools} ${target_libs} ${target_tools}"
