INSTALL

To build xvi on Linux systems:

Linux
-----
	cd src
	make -f makefile.pos
	install -s xvi /usr/local/bin/
	install xvi.help /usr/local/lib/
	install ../doc/xvi.1 /usr/local/share/man/man1/

To make the Debian/Ubuntu package, say
	apt-get install debhelper build-essential libncurses-dev
	dpkg-buildpackage -rfakeroot
which will create you ../xvi*.deb that you can install with
	dpkg -i ../xvi*.deb

To run the test suite ("make check") you will also need to
	apt-get install expect tclsh
See test/README to run it without an X display.

To compile for smallest code size, install clang and use
	make CC=clang OPTFLAG=-Os

Installing required packages from source
----------------------------------------
xvi needs a termcap library and, to run the test suite, tcl and expect.
To install these from source code under your home directory:

# Termcap
	wget https://ftp.gnu.org/gnu/termcap/termcap-1.3.1.tar.gz
	gunzip < termcap*gz | tar xf -
	(cd termcap* && ./configure --prefix=$HOME && make install)
# Tcl
	wget http://prdownloads.sourceforge.net/tcl/tcl8.6.6-src.tar.gz
	gunzip < tcl*gz | tar xf -
	( cd tcl*/unix && ./configure --prefix=$HOME && make install )

# Find local versions. You can add these to .profile
export PATH=$HOME/bin:$PATH
export LD_LIBRARY_PATH=$HOME/lib
export TCL_LIBRARY=$HOME/lib/tcl8.6
export TCLLIBPATH=$HOME/lib
export MANPATH=$HOME/man:$MANPATH

# expect
wget https://downloads.sf.net/project/expect/Expect/5.45/expect5.45.tar.gz
gunzip < expect*gz | tar xf -
( cd expect*
  # On aarch64, expect 5.45 needs tclconfig/config.sub modifying to add:

         | alphapca5[67]-* | alpha64pca5[67]-* | arc-* \
         | arm-*  | armbe-* | armle-* | armeb-* | armv*-* \
>        | aarch64-* \
         | avr-* \
         | bs2000-* \

  ./configure --prefix=$HOME  # --build=aarch64-suse-linux
  make install
)
