# !!!!!!!!!!! SUN resolv LIBRARY !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
# To include resolv in the LIBS="" list for SUN 3, 4 or Solaris OS,
# point RESOLVLIB to that library.  You need this if you get the message
# "Alert!:  Unable to connect to remote host" whenever you try to
# access a host other than localhost and have made Lynx without it.
# See the PROBLEMS file for more information.
#RESOLVLIB= -lresolv

# !!!!!!!!!!!!!  DIRECT WAIS ACCESS !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
# If you are adding direct wais access you must fill in the
# location of wais.a, client.a and the standard math library, libm.a.
# You can pick up the most current freeWAIS sources from
#	ftp://ftp.cnidr.org/pub/NIDR.tools/freewais
# If you are using freeWAIS-0.202 or older, include -DDECLARE_WAIS_LOGFILES
# in your SITE_DEFS.
# Please put an ABSOLUTE address here if you want it to work!
#WAISLIB= ../../freeWAIS-0.202/bin/client.a ../../freeWAIS-0.202/bin/wais.a /usr/lib/libm.a

# !!!!!!!!!!!!! SLANG Support (For color version of Lynx). !!!!!!!!!!!!!!!!
# The slang library is an alternative to curses, developed by John E. Davis
# (davis@space.mit.edu).  Version 0.99-27 or higher is available from
#	ftp://space.mit.edu/pub/davis
# It provides color support for Lynx.

# !!!!!!!!!!!!! NCURSES Support (For color version of Lynx). !!!!!!!!!!!!!!
# If you need ncurses, the latest version can always be found
# in ftp://ftp.clark.net/pub/dickey/ncurses/
# or ftp://ftp.gnu.org/pub/gnu/

# Also be sure to check out the compilation symbols in userdefs.h
# before building Lynx!

# If you apply patches which require linking to site-specific libraries, set
# SITE_LIBS to those libraries.
SITE_LIBS= # Your libraries here

# Set SITE_LYDEFS to one or more of the defines for the WWW Library:
SITE_LYDEFS = # Your defines here

# Set SITE_DEFS to one or more of the defines for lynx below:
SITE_DEFS = # Your defines here

# defines for which there are no configure options:
# -DHP_TERMINAL    For DIM workaround to REVERSE problems on HP terminals.
# -DIGNORE_CTRL_C  Define if Control-C shouldn't exit lynx.
# -DNOPORT         if you must use PASV instead of PORT for FTP
# -DNO_CPU_LIMIT   Disables Max CPU timeout (includes CLOCKS_PER_SECOND)
# -DSHORTENED_RBIND  For a SOCKSified lynx with the short version of Rbind.
# -DSLANG_MBCS_HACK prevent cutoff lines when using UTF8 console (slang only)
#
# if you are linking to freeWAIS-0.202 or older, you should define this
# in SITE_DEFS
#
# -DDECLARE_WAIS_LOGFILES
#
# if you have the reverse clear screen problem of some SUN4 systems you
# should define this in SITE_DEFS
#
# -DREVERSE_CLEAR_SCREEN_PROBLEM
#
# if you have an SVR4 system with the "type any key" problem, try defining
# this in LYFLAGS (SITE_LYDEFS) and SITE_DEFS
#
# -DSVR4_BSDSELECT
#
# Old Data General systems may need this in their SITE_LYDEFS
# for their inet_addr(host) calls.
#
# -DDGUX_OLD

# defines which have configure options   (see INSTALLATION, Section II-1c.):
# -DARCHIVE_ONLY
# -DDIRED_SUPPORT
# -DDISP_PARTIAL
# -DDONT_TRACK_INTERNAL_LINKS
# -DEXEC_LINKS
# -DEXEC_SCRIPTS
# -DEXP_CHARTRANS_AUTOSWITCH
