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

59 ## These two lists are of directories that are to be removed from the
60 ## ${configdirs} list for either cross-compilations or for native-
61 ## compilations. For example, it doesn't make that much sense to
62 ## cross-compile Emacs, nor is it terribly useful to compile xiberty in
63 ## a native environment.

73 cross_only="xiberty libgloss newlib"
75 ## All tools belong in one of the four categories, and are assigned above
76 ## We assign ${configdirs} this way to remove all embedded newlines. This
77 ## is important because configure will choke if they ever get through.
78 ## ${configdirs} is directories we build using the host tools.
79 ## ${target_configdirs} is directories we build using the target tools.
