#	Set LEX.

#	specify a prefix other than `yy').  The -P flag was added at
#	the same time a -V (version) flag was added (version 2.4.1),
#	so if `flex' understands -V, it'll understand -P (checking
#	for -P directly requires a flex input file).
#
#	1. If `LEX' is not set, look for `flex' and set `LEX' to
#	   `flex' if found.
#	2. If `flex' was found, see if it understands -V.  If so,
#	   set `scanner_src' and `typer_src' to have `flex' generate
#	   the C files from the flex input files
#	   ascend4/compiler/scanner.l & ascend4/interface/typelex.l
#	   We don't need to look for libfl.a since we define
#	   yywrap() ourselves.
#	3. If `flex' wasn't found or was found but isn't new enough:
#	   a. Print a warning message
#	   b. Set `scanner_src' and `typer_src' to use pre-generated
#	      C files for the flex files mentioned in (2).

#--------------------------------------------------------------------
#	Check for the existence of various libraries.  The order here
#	is important, so that then end up in the right order in the
#	command line generated by make.  The -lsocket and -lnsl
#	libraries require a couple of special tricks:
#	1. Use "connect" and "accept" to check for -lsocket, and
#	   "gethostbyname" to check for -lnsl.
#	2. Use each function name only once:  can't redo a check
#	   because autoconf caches the results of the last check
#	   and won't redo it.
#	3. Use -lnsl and -lsocket only if they supply procedures that
#	   aren't already present in the normal libraries.  This is
#	   because IRIX 5.2 has libraries, but they aren't needed and
#	   they're bogus:  they goof up name resolution if used.
#	4. On some SVR4 systems, can't use -lsocket without -lnsl
#	   too. To get around this problem, check for both libraries
#	   together if -lsocket doesn't work by itself.

#--------------------------------------------------------------------
#	The following comes directly from the configure.in file for
#	Tcl8.0.
#
#	The statements below define a collection of symbols related to
#	dynamic loading and shared libraries:
#
#	DL_OBJS -	Name of the object file that implements dynamic
#			loading for ASCEND on this system.
#	DL_LIBS -	Library file(s) to include in tclsh and other base
#			applications in order for the "load" command to work.
#	LD_FLAGS -	Flags to pass to the compiler when linking object
#			files into an executable application binary such
#			as tclsh.
#	LD_SEARCH_FLAGS-Flags to pass to ld, such as "-R /usr/local/tcl/lib",
#			that tell the run-time dynamic linker where to look
#			for shared libraries such as libtcl.so.  Depends on
#			the variable LIB_RUNTIME_DIR in the Makefile.
#	MAKE_LIB -	Command to execute to build the ASCEND library;
#			differs depending on whether or not ASCEND is being
#			compiled as a shared library.
#	SHLIB_CFLAGS -	Flags to pass to cc when compiling the components
#			of a shared library (may request position-independent
#			code, among other things).
#	SHLIB_LD -	Base command to use for combining object files
#			into a shared library.
#	SHLIB_LD_LIBS -	Dependent libraries for the linker to scan when
#			creating shared libraries.  This symbol typically
#			goes at the end of the "ld" commands that build
#			shared libraries. The value of the symbol is
#			"${LIBS}" if all of the dependent libraries should
#			be specified when creating a shared library.  If
#			dependent libraries should not be specified (as on
#			SunOS 4.x, where they cause the link to fail, or in
#			general if ASCEND and Tk aren't themselves shared
#			libraries), then this symbol has an empty string
#			as its value.
#	SHLIB_SUFFIX -	Suffix to use for the names of dynamically loadable
#			extensions.  An empty string means we don't know how
#			to use shared libraries on this platform.
#	ASC_LIB_FILE -	Name of the file that contains the ASCEND library, such
#			as libtcl7.8.so or libtcl7.8.a.
#	ASC_LIB_SUFFIX -Specifies everything that comes after the "libtcl"
#			in the shared library name, using the $VERSION variable
#			to put the version in the right place.  This is used
#			by platforms that need non-standard library names.
#			Examples:  ${VERSION}.so.1.1 on NetBSD, since it needs
#			to have a version after the .so, and ${VERSION}.a
#			on AIX, since the ASCEND shared library needs to have
#			a .a extension whereas shared objects for loadable
#			extensions have a .so extension.  Defaults to
#			${VERSION}${SHLIB_SUFFIX}.
#--------------------------------------------------------------------

# Step 1: set the variable "system" to hold the name and version number
# for the system.  This can usually be done via the "uname" command, but
# there are a few systems, like Next, where this doesn't work.

# Changed this to use the "$host" variable from AC_CANONICAL_HOST

# Step 2: check for existence of -ldl library.  This is needed because
# Linux can use either -ldl or -ldld for dynamic loading.

# Step 4: If pseudo-static linking is in use (see K. B. Kenny, "Dynamic
# Loading for Tcl -- What Became of It?".  Proc. 2nd Tcl/Tk Workshop,
# New Orleans, LA, Computerized Processes Unlimited, 1994), then we need
# to determine which of several header files defines the a.out file
# format (a.out.h, sys/exec.h, or sys/exec_aout.h).  At present, we
# support only a file format that is more or less version-7-compatible. 
# In particular,
#	- a.out files must begin with `struct exec'.
#	- the N_TXTOFF on the `struct exec' must compute the seek address
#	  of the text segment
#	- The `struct exec' must contain a_magic, a_text, a_data, a_bss
#	  and a_entry fields.
# The following compilation should succeed if and only if either sys/exec.h
# or a.out.h is usable for the purpose.
#
# Note that the modified COFF format used on MIPS Ultrix 4.x is usable; the
# `struct exec' includes a second header that contains information that
# duplicates the v7 fields that are needed.
# Step 5: disable dynamic loading if requested via a command-line switch.

#--------------------------------------------------------------------
#	TCL / TK / TK-TABLE
#
#	The user can specify the location of the Tcl and/or Tk
#	libraries using the --with-tcl and --with-tk configure
#	options. Print a warning if the user tries to say
#	--without-tcl since ASCEND requires Tcl/Tk.
#
#	If the user does not specify the location, we need to search
#	for either shared or static versions of the Tcl and Tk
#	libraries, and they must be for version 8.x of Tcl/Tk.
#
#	Check for the static Tcl library in a list of reasonable
#	locations.  If we find it, verify that it is from Tcl 8.0 by
#	looking for the symbol `TclCompileCatchCmd'.  Remember, we
#	need the math library and the dynamic loader library (-ldl or
#	-ldld) to avoid undefined symbols when we test the version of
#	the Tcl library.
#
#	If we can't find a static Tcl8.0 library, try to find a
#	dynamic one by calling AC_CHECK_LIB and looking for the
#	function `TclCompileCatchCmd'.  If we fail, print an error
#	message and exit configure.
#
#	Search for a version of tcl.h that contains `8.' in the
#	TCL_MAJOR_VERSION macro; we look in a list of reasonable
#	locations, then call AC_EGREP_HEADER to look for us.
#
#	Repeat the process for the Tk library; the symbol we want is
#	`Tk_NameOfFont'; remember we need the X library---and all the
#	libraries it needs---as well as the Tcl library to avoid
#	undefined symbols when we test the version of the Tk library.
#
#	The user can use --with-tktable to specify a location for a
#	static version of the Tk-Table library.  If a value is
#	specified, assume it is good and define the cpp macro
#	STATIC_TABLE.
#
#	If a value is not specified, look for libTktable.a; if we
#	find it, assume it works and define the cpp macro
#	STATIC_TABLE.  If we don't find it, assume ASCEND will be
#	able to dynamically load it at run time and tell the user
#	about our assumption.

#--------------------------------------------------------------------
#	FORTRAN
#
#	ASCEND uses the LSOD integrator and is capable of working
#	with CONOPT and with MINOS.  These libraries are written in
#	Fortran; to use them, configure needs to find a Fortran
#	compiler and the necessary Fortran libraries (e.g.,
#	libF77.a).  LSOD, CONOPT, and MINOS also require the BLAS and
#	LINPACK libraries to avoid undefined symbols at link time.
#
#	The builder can specify the location of
#	* the Fortran compiler and libraries using
#	  --with-fortran=<compiler>,<libraries>
#	* the BLAS library using
#	  --with-blas=<blas-library>
#	* the LINPACK library using
#	  --with-linpack=<linpack-library>
#	* the LSOD library using
#	  --with-blas=<lsod-library>
#	* the CONOPT library using
#	  --with-conopt=<conopt-library>
#	* the MINOS library using
#	  --with-minos=<minos-library>   <===currently disabled
#	The builder can disable some parts of the fortran build using
#	the --without-<package> configure option.
#
#	If the user does not specify the locations of the compiler
#	and the libraries and does not disable them, configure
#	attempts to find them.
#
#	Building with LSOD, CONOPT, and/or MINOS is further
#	complicated by the dependencies between these libraries and
#	the BLAS and LINPACK libraries.
#
#	If we cannot find a Fortran compiler, we disable all Fortran
#	code (LSOD, CONOPT, and MINOS).  Otherwise, look for the
#	Fortran libraries (e.g., libF77.a) based on the type of
#	machine we are compiling on.
#
#	If Fortran is enabled, we need to find a compiled BLAS
#	library or source code.  Check for the machine's libblas.a
#	and ASCEND's libascblas.a; if those fail, check for the
#	libascblas.a source code; if that fails, we disable all
#	Fortran (LSOD, CONOPT, MINOS).
#
#	If Fortran is enabled, we need to find a compiled LINPACK
#	library or source code.  Check for the machine's liblpak.a
#	and ASCEND's libasclpak.a; if those fail, check for the
#	libasclpak.a source code; if that fails, we disable all
#	Fortran (LSOD, CONOPT, MINOS).
#
#	If Fortran is enabled, we try to find a compiled LSOD library
#	or source code.  Check for a libinteg.a; if that fails, check
#	for the libinteg.a source code; if that fails, we disable
#	LSOD.  If we find LSOD, define STATIC_LSOD.
#
#	If Fortran is enabled, we try to find a compiled OPTSQP
#	library or source code.  Check for a librsqp.a; if that fails,
#	check for the librsqp.a source code; if that fails, we disable
#	OPTSQP.  If we find RSQP, define STATIC_OPTSQP.
#
#	If Fortran is enabled, we try to find a compiled CONOPT
#	library.  Check for a libconsub.a; if that fails, we disable
#	CONOPT.  If we find CONOPT, define STATIC_CONOPT; if not,
#	tell the user where to find CONOPT using the contact
#	information from the nonlinear programming FAQ:
#    http://www.mcs.anl.gov/home/otc/Guide/faq/nonlinear-programming-faq.html
#
#	If Fortran is enabled, we try to find a compiled MINOS
#	library or source code.  Check for a libminos54.a; if that
#	fails, check for the libminos54.a source code; if that fails,
#	we disable MINOS.  If we find MINOS, define STATIC_MINOS; if
#	not, tell the user where to find MINOS using the contact
#	information from the nonlinear programming FAQ:

#--------------------------------------------------------------------
#	Other trees which may or may not be present.  If present,
#	generate the Makefiles in the tree unless the user passes in
#	a --without-<package> argument.
#
#	Valid <package> values are: TK, models, help
#
#	We could have `configure' do this for us via
#	AC_CONFIG_SUBDIRS, but `configure' scripts in the trees can
#	only be one directory removed from this configure script.
#	For example, it would be nice to have `models' under
#	`ascend4', but `configure' doesn't like `ascend4/models' as
#	an argument to AC_CONFIG_SUBDIRS.
#
#	To get around this problem, we do things by hand. :-)
#
#	If the user gives a --without-<package> argument, we have
#	nothing to do for that package.
#
#	Otherwise,
#	* Set `subdir_file_exists' to a file that should exist in the
#	  subtree---this is how we know that the subtree is really
#	  there.
#	* Set `subdir_locations' to the list of locations, relative
#	  to this configure script, where the subtree may live.
#	* Set `subdir_output' to the list of makefiles to generate;
#	  the variable `subdir_root' in this list will be replaced
#	  with the correct value from `subdir_locations'.
#
#	To see which (if any) of the values in `subdir_locations' is
#	the correct one, we set `subdir_root' to each value in
#	`subdir_locations' and check for the existence of
#	$fullpathsrcdir/$subdir_root/$subdir_file_exists, where
#	$fullpathsrcdir is the full path to the source directory.  If
#	that file exists, we
#	* Set <package>_dir_root to ../$subdir_root.  The "../" is
#	  needed since this value is used in the `ascend4' directory
#	  and $subdir_root is relative to the parent of `ascend4'.
#	* Substitute the value of $subdir_root into `subdir_output'
#	  and set the result to <package>_makefiles: the list of
#	  Makefiles for configure to generate.
#	* Each package needs to be able to find its way back to
#	  ascend4/ConfigAscend; it needs to go back up the tree
#	  however many levels deep it is---i.e., `foo/bar/baz' should
#	  become `../../..' and this does it: sed 's,[^/][^/]*,..,g'
#	  but we need to quote the [] from m4, so we get this bizarre
#	  thing: sed 's,[[^/][^/]]*,..,g' Set <package>_topbuilddir
#	  to this result.
#	* Exit the loop.
