# This tcl script generates the makefile.
#
# This script begins life as "makemake.tcl.in".  A "configure"
# shell script will read "makemake.tcl.in" and generate
# "makemake.tcl".  The makemake.tcl script then runs to
# produce the makefile.
#
# This script needs to know the following information about
# the build environment:
#
#   *   The location of the source code.  
#
#       This is the name of the directory that contains 
#       makemake.tcl.in and configure.  The build products 
#       (the *.o and *.exe files) and makemake.tcl will
#       be written into the working directory.  The working
#       directory can and should be distinct and separate from
#       the source directory.  The source directory can be
#       on a read-only filesystem.  The name of the source 
#       directory is stored in the $TOP variable.
#
#   *   How to compile and link C code into command-line programs to
#       run on the build platform.
#
#       The compiler command name is stored in $BCC.  If any
#       libraries are required, they are stored in $BLIBS
#
#   *   The suffix to give to command-line programs that run
#       on the build platform.
#
#       This is stored in $BEXE
#
#   *   How to compile C modules into *.o files for the target
#       platform.
#
#       This is the $TCC variable.
#
#   *   The suffix to give to programs that run on the target
#       platform.
#
#       This is the $TEXE variable.
#
#   *   How to link *.o files produced by $TCC command into
#       an executable that runs on the target platform.
#
#       The $TLINK command does the linking.  It requires
#       arguments stored in $TLIBS
#
#   *   The names of directories containing Tcl script libraries
#       that are compatible with the Tcl C libraries on the
#       target platform.
#
#       These are the $TCLSCRIPTDIR and $TKSCRIPTDIR variables.
#
#   *   The name of a tclsh that works on the build platform.
#
#       This is the $BTCLSH variable.
#
# All of the above information is discovered by the configure
# shell script.  The configure shell script then inserts the 
# information here:
#
set TOP           [list @srcdir@]
set BCC           [list @BUILD_CC@ @BUILD_CFLAGS@]
set BLIBS         [list @BUILD_LIBS@]
set BEXE          [list @BUILD_EXEEXT@]
set BTCLSH        [list @BUILD_TCLSH@]
set TCC           [list @TARGET_CC@ @TARGET_CFLAGS@ -I. @TARGET_TK_INC@ \
                    @TARGET_X_INC@ @TARGET_TCL_INC@ @TARGET_BLT_INC@]
set TEXE          [list @TARGET_EXEEXT@]
set TLINK         [list @TARGET_LINK@ @TARGET_LFLAGS@]
set TLIBS         [list @TARGET_BLT_LIBS@ @TARGET_TK_LIBS@ @TARGET_X_LIBS@ \
                    @TARGET_TCL_LIBS@ @TARGET_LIBS@]
set TCLSCRIPTDIR  [list @TARGET_TCL_SCRIPT_DIR@]
set TKSCRIPTDIR   [list @TARGET_TK_SCRIPT_DIR@]
#
# The "configure" script makes no changes beyond this point.
