#
#======================================================================
#
#  There are various small changes needed when compiling calctool on
#  different systems. These have been isolated here, and should
#  be uncommented if needed.
#
#======================================================================
#
#  Calctool uses an helpfile to supply online help for each key.
#  By default this file is called "calctool.help", and is looked
#  for in every directory on the users search path. You can also
#  override it's location and name at runtime with the -h option.
#  It can also be specified here by uncommenting the following
#  macro definition and setting appropriately.
#
HELPNAME        = -DHELPNAME=\"%%DATADIR%%/calctool.help\"
#-----------------------------------------------------------------------
#  An attempt is now made at using a portable math library. You should
#  carefully setup the following three definitions.
#
#  One of the things this is not the same on all machines is the
#  floating point format. If your machine does *not* use IEEE floating
#  point format, then the following definition needs to be uncommented.
#
#NOIEEE             = -DIEEE
#-----------------------------------------------------------------------
#  Some machines send a SIGFPE on math errors despite the presense
#  of the handler routine in calctool.c. If calctool cores when you
#  divide by zero, uncomment this and calctool will ignore FPE
#  signals.
#
#STUPID_FPE         = -DSTUPID_FPE
#-----------------------------------------------------------------------
#  Not all machines have the index() string library function. If you
#  don't have this function then you should uncomment the NOINDEX
#  definition below.
#
#NOINDEX         = -DNOINDEX
#-----------------------------------------------------------------------
#  If you are compiling the MGR version, then the following three
#  definitions should be uncommented.
#
#MGRHOME         = /usr/mgr
#MGRPARAM        = -DMGRHOME=\"$(MGRHOME)\"
#MGRINCDIR       = -I$(MGRHOME)/include
#-----------------------------------------------------------------------
#  If you are compiling the NeWS version, then the following definition
#  should be uncommented and set to the default location for the calctool
#  PostScript file, which is downloaded to the NeWS server.
#
#NEWSFILE        = -DNEWSFILE=\"$(LIBDIR)/calctool.ps\"
#-----------------------------------------------------------------------
#  Calctool loads a run control file when it starts. By default
#  this file is called ".calctoolrc", and is taken from the users
#  home directory. If there is a similar file in the current directory,
#  then these values override the default ones. Its name and location
#  can also be specified here by uncommenting the following macro
#  definition and setting appropriately.
#
#RCNAME          = -DRCNAME=\".calctoolrc\"
#-----------------------------------------------------------------------
#  If you not running under a BSD4.3 derived system, the parameters
#  to the select call are different, and this definition should be
#  uncommented. You need to uncomment this for SunOS v3.x.
#
#SELTYPE        = -DNO_4.3SELECT
#-----------------------------------------------------------------------
#  Note that with SunOS v4.x it is possible to create a shared library
#  for the calctool routines. If you wish to do this, then you should
#  uncomment the other three definitions below, commented out the initial
#  two.
#
#LIBNAME         = libcalctool.a
#CALCLIB	        = $(LIBNAME)
#
# Shared library definitions. Uncomment if required.
LIBNAME         = libcalctool.so.1
CALCLIB         = -L . -lcalctool
SHLIB           = %%FPIC%%
#-----------------------------------------------------------------------
#  If you are not running under a BSD4.3 derived system, then the
#  second parameter to a select call is a pointer to an integer function,
#  and this definition needs to be uncommented. You need to uncomment this
#  for SunOS v3.x.
#
#SIGRET         = -DNO_4.3SIGNAL
#--------------------------------------------------------------------------
#  Calctool endevours to provide a numeric keypad using the right function
#  keypad. The Sun3 keyboard has a different pad setup to the Sun4 keyboard.
#  If you wish to use these function keys with a Sun4 keyboard, then you
#  need to uncomment the following definition.
#
SUN4_KEYBOARD  = -DSUN4_KEYBOARD
#-------------------------------------------------------------------------
#  If you are running SunOS v3.x, then pr_ttext doesn't exist, and
#  you must uncomment this definition.
#
#TTEXT          = -DNO_PR_TTEXT
#-------------------------------------------------------------------------
#  If you are compiling the X11 version and the X11 include and
#  library files are not in a standard place, then the following
#  two lines should be uncommented, and set appropriately.
#
X11INCDIR         = -I%%X11BASE%%/include
X11LIBDIR         = -L%%X11BASE%%/lib
#-------------------------------------------------------------------------
#  If you are compiling the XView version, then the following two lines
#  should be uncommented.
#
XVIEWINCDIR      = -I%%X11BASE%%/include
XVIEWLIBDIR      = -L%%X11BASE%%/lib
