3 ## This file is a shell script fragment that supplies the information
4 ## necessary to tailor a template configure script into the configure
5 ## script appropriate for this directory. For more information, check
6 ## any existing configure script.
8 ## Be warned, there are two types of configure.in files. There are those
9 ## used by Autoconf, which are macros which are expanded into a configure
10 ## script by autoconf. The other sort, of which this is one, is executed
11 ## by Cygnus configure.
13 ## For more information on these two systems, check out the documentation
14 ## for 'Autoconf' (autoconf.texi) and 'Configure' (configure.texi).

18 ### To add a new directory to the tree, first choose whether it is a target
19 ### or a host dependent tool. Then put it into the appropriate list
20 ### (library or tools, host or target), doing a dependency sort. For
21 ### example, gdb requires that byacc (or bison) be built first, so it is in
22 ### the ${host_tools} list after byacc and bison.
25 # these libraries are used by various programs built for the host environment
27 host_libs="mmalloc libiberty opcodes bfd readline glob gash tcl tk tclX"
29 # these tools are built for the host environment
31 host_tools="texinfo byacc flex bison binutils ld gas gcc gdb make patch
32 prms send-pr gprof gdbtest tgas etc expect dejagnu sim
33 m4 autoconf ispell grep diff rcs cvs fileutils shellutils
34 textutils wdiff find emacs uudecode hello tar gzip indent
35 recode release sed utils"
38 # these libraries are built for the target environment, and are built after
39 # the host libraries and the host tools (which may be a cross compiler)
41 target_libs="libm xiberty newlib libio libg++"
44 # these tools are built using the target libs, and are intended to run only
45 # in the target environment. we currently have none.
47 # note: any program that *uses* libraries that are in the "target_libs"
48 # list belongs in this list. those programs are also very likely
49 # candidates for the "native_only" list which follows
53 ################################################################################
55 ## These two lists are of directories that are to be removed from the
56 ## ${configdirs} list for either cross-compilations or for native-
57 ## compilations. For example, it doesn't make that much sense to
58 ## cross-compile Emacs, nor is it terribly useful to compile xiberty in
59 ## a native environment.
61 # directories to be built in the native environment only
63 native_only="autoconf cvs emacs fileutils find grep groff gzip hello indent
64 ispell m4 rcs recode sed shellutils tar textutils gash tk uudecode wdiff
67 # directories to be built in a cross environment only
69 cross_only="xiberty newlib"
71 ## All tools belong in one of the four categories, and are assigned above
72 ## We assign ${configdirs} this way to remove all embedded newlines. This
73 ## is important because configure will choke if they ever get through.
