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 ${host_tools} list after byacc and bison.
25 # these libraries are used by various programs built for the host environment
27 host_libs="mmalloc libiberty opcodes bfd readline glob gash tcl tk tclX"
29 # these tools are built for the host environment
31 host_tools="texinfo byacc flex bison binutils ld gas gcc gdb make patch
32 prms send-pr gprof gdbtest tgas etc expect dejagnu sim
33 m4 autoconf ispell grep diff rcs cvs dosutils fileutils shellutils
34 textutils wdiff find emacs uudecode hello tar gzip indent
38 # these libraries are built for the target environment, and are built after
39 # the host libraries and the host tools (which may be a cross compiler)
41 target_libs="libm xiberty newlib libio libg++"
43 ## start-sanitize-chill
44 target_libs="${target_libs} chill chillrt"
47 # these tools are built using the target libs, and are intended to run only
48 # in the target environment. we currently have none.
50 # note: any program that *uses* libraries that are in the "target_libs"
51 # list belongs in this list. those programs are also very likely
52 # candidates for the "native_only" list which follows
56 ################################################################################
58 ## These two lists are of directories that are to be removed from the
59 ## ${configdirs} list for either cross-compilations or for native-
60 ## compilations. For example, it doesn't make that much sense to
61 ## cross-compile Emacs, nor is it terribly useful to compile xiberty in
62 ## a native environment.
64 # directories to be built in the native environment only
66 native_only="autoconf cvs emacs fileutils find grep groff gzip hello indent
67 ispell m4 rcs recode sed shellutils tar textutils gash tk uudecode wdiff
70 # directories to be built in a cross environment only
72 cross_only="xiberty newlib"
74 ## All tools belong in one of the four categories, and are assigned above
