binutils-gdb/configure.in

##############################################################################

## 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 tclX"

# these tools are built for the host environment
#
host_tools="texinfo byacc flex bison binutils ld gas gcc gdb make patch
	    prms send-pr gprof gdbtest tgas etc expect dejagnu sim
            m4 autoconf ispell grep diff rcs cvs fileutils shellutils
	    textutils wdiff find emacs uudecode hello tar gzip indent
	    recode release"


# 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++"

## start-sanitize-chill
target_libs="${target_libs} chill chillrt"
## end-sanitize-chill

# these tools are built using the target libs, and are intended to run only
# in the target environment.  we currently have none.
#
# note: any program that *uses* libraries that are in the "target_libs"
# list belongs in this list.  those programs are also very likely
# candidates for the "native_only" list which follows
#
target_tools="groff"

################################################################################

## 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="autoconf cvs emacs fileutils find grep groff gzip hello indent
             ispell m4 rcs recode sed shellutils tar textutils tk uudecode wdiff
	     gprof"

# directories to be built in a cross 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}"
