# libti* and tilp are compiled with a proposed set of configuration options,
# but you may wish to use others. The complete list is available through
# `./configure --help` run in $SRCDIR/tilp/libticonv, $SRCDIR/tilp/libtifiles,
# $SRCDIR/tilp/libticables, $SRCDIR/tilp/libticalcs, $SRCDIR/tilp/tilp and $SRCDIR/tilp/gfm.


# The prefix where the binaries will be installed, e.g. $HOME, /usr, /usr/local, /usr/share.
#
# NOTES:
# * if installing to e.g. $HOME or /usr/local, you'll certainly have to execute
# $ export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:$HOME/lib/pkgconfig
# (or the equivalent setenv command for csh derivatives).
# and put it in your ~/.bashrc (~/.cshrc, etc.), before executing this script.
#
# * after successful installation, you may have to add $PREFIX/bin to $PATH,
# and $PREFIX/lib to $LD_LIBRARY_PATH, for the SVN versions of libti*, tilp & gfm
# to get picked up.

# MANDATORY dependencies for compiling and running libti* and tilp:
# (Debian and Fedora package names are given)
# * pkg-config
# * GNU autoconf, automake, libtool
# * glib 2.x development files (libglib2.0-dev, glib2-devel)
# * zlib development files (zlib1g-dev, zlib-devel)
# * libusb development files (libusb-dev, libusb-devel) - WARNING, only libusb 0.1.x (not even the compatibility layer for 1.0) supported for now !
# * GTK+ 2.x and Glade development files (libgtk2.0-dev + libglade2-dev, gtk2-devel + libglade2-devel)
# * SDL 1.2 development files (libsdl1.2-dev, SDL-devel)
# * GNU gettext
# * GNU bison, flex
# * GNU groff, texinfo
# * XDG utils
#
# Optional dependencies:
# * KDE 3.x development files (kdelibs4-dev, kdelibs3-devel), if you want to compile tilp with support for the KDE file dialog.
#   (this implies Qt development files)
