# Everything used to go into /usr/lib/lynx, now here's where various
# things will end up (look at userdefs.h and makefile after you run
# configure if you want to change it):
# /etc/lynx.cfg
# /etc/lynx.lss
# /etc/mailcap
# /etc/mime.types
# /usr/share/lynx_doc/
# /usr/share/lynx_help/
#
# If you want mailcap and mime.types to go somewhere other than /etc,
# specify that with --with-mime-libdir
# If you want lynx.lss to go somewhere else, specify --with-lss-file
# If you want lynx.cfg to go somewhere else, specity --with-cfg-file

# If you have OpenSSL < 1.1.0 installed under the default source prefix
# of /usr/local/ssl, use --with-ssl=/usr/local/ssl and it should work
# for lib or lib64

# Configure the build

--with-screen=ncurses --enable-color-style --enable-default-colors \
--enable-scrollbar --enable-nsl-fork --enable-gzip-help --with-bzlib \
