- ## 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 gash tcl tk tclX"
-
- # these tools are built for the host environment
- #
- host_tools="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 sed utils"
-
-
- # 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 libio libg++"
-
-
- # 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

- ## 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.
