##AWW
##AWW   We put the .o files when compiling into a tree structure
##AWW   relative to the directory in which we currently reside,
##AWW   while the .c and .h files are in a similar tree structure
##AWW   relative to the configure instruction we invoke.  This
##AWW   allows one to have separate .o files in their own tree when
##AWW   compiling for different operating systems.
##AWW
##AWW   Example 1 (same directories)
##AWW   Current directory one is in:    /home/me/trunk/base/unixAC213
##AWW   Directory containing configure: /home/me/trunk/base/unixAC213
##AWW   Command to invoke configure:    ./configure
##AWW       $ascpwd will be: /home/me/trunk/base/unixAC213
##AWW       $srcdir will be: .
##AWW
##AWW   Example 2 (different directories, abs path for command)
##AWW   Current directory one is in:    /home/me/trunk/base/newTree
##AWW   Directory containing configure: /home/me/trunk/base/unixAC213
##AWW   Command to invoke configure:    /home/me/trunk/base/unixAC213/configure
##AWW       $ascpwd will be: /home/me/trunk/base/newTree
##AWW       $srcdir will be: /home/me/trunk/base/unixAC213
##AWW
##AWW   Example 3 (different directories, rel path for command)
##AWW   Same as Example 2
##AWW   Command to invoke configure:    ../unixAC213/configure
##AWW       $ascpwd will be: /home/me/trunk/base/newTree (same as in Example 2)
##AWW       $srcdir will be: ../unixAC213
##AWW
##AWW   Key elements of the source tree are:
##AWW       code/trunk/trunk/base/unixAC213/configure
##AWW       code/trunk/trunk/base/generic
##AWW       code/trunk/tcltk98
##AWW   where $srcdir is pointing to /home/me/trunk/base/unixAC213, the folder
##AWW   containing "configure"
##AWW
##AWW   Configure is located at:
##AWW       $srcdir/configure
##AWW   while the .c/.h files one wants are in:
##AWW       $srcdir/../generic/compiler
##AWW       $srcdir/../generic/general
##AWW       $srcdir/../generic/packages
##AWW       $srcdir/../generic/solver
##AWW       $srcdir/../generic/utilities
##AWW       $srcdir/../../tcltk98/generic/interface
##AWW
##AWW   Each of these directories contain Makefiles and possible
##AWW   need to find .h files in the other directories.  For example
##AWW   the include statements are always of the form
##AWW       #include compiler/slv3.h or
##AWW       #include interface/SlvProc.h
##AWW
##AWW   A safe include path should assume one is a directory with any
##AWW   of these .h and .c files and one needs to find a .h file in
##AWW   any other of them.  The following paths should do it.   
##AWW   
##AWW   If in compiler, general, packages, solver, utilities
##AWW       ..                        for general, packages, etc
##AWW       ../../../tcltk98/generic  for interface
##AWW   If in interface
##AWW       ..                        for interface
##AWW       ../../../base/generic        for compiler, general, ..

#	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.

AC_CHECK_LIB(dl, dlopen, have_dl=yes, have_dl=no)

#	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

#--------------------------------------------------------------------
#	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
#AWW20041208:#	  needed since this value is used in the `ascend4' directory
#	  needed since this value is used in the `generic' directory
#AWW20041208:#	  and $subdir_root is relative to the parent of `ascend4'.
#	  and $subdir_root is relative to the parent of `generic'.
#	* 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.
