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 tcl tk"
29 # these tools are built for the host environment
31 host_tools="texinfo byacc flex bison binutils ld gas gcc gdb make patch
32 send_pr gprof gdbtest tgas etc expect deja-gnu z8ksim
33 m4 autoconf ispell grep diff rcs cvs fileutils shellutils
34 textutils wdiff find emacs"
37 # these libraries are built for the target environment, and are built after
38 # the host libraries and the host tools (which may be a cross compiler)
40 target_libs="libm xiberty newlib chillrt libg++"
42 # these tools are built using the target libs, and are intended to run only
43 # in the target environment. we currently have none.
45 # note: any program that *uses* libraries that are in the "target_libs"
46 # list belongs in this list. those programs are also very likely
47 # candidates for the "native_only" list which follows
51 ################################################################################
53 ## These two lists are of directories that are to be removed from the
54 ## ${configdirs} list for either cross-compilations or for native-
55 ## compilations. For example, it doesn't make that much sense to
56 ## cross-compile Emacs, nor is it terribly useful to compile xiberty in
57 ## a native environment.
59 # directories to be built in the native environment only
61 native_only="autoconf cvs diff emacs fileutils find grep groff ispell m4
62 rcs sed shellutils textutils wdiff"
64 # directories to be built in a cross environment only
66 cross_only="xiberty newlib"
68 ## All tools belong in one of the four categories, and are assigned above
70 configdirs="${host_libs} ${host_tools} ${target_libs} ${target_tools}"
