# libti* and tiemu 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/tiemu/tiemu.


# The prefix where the binaries will be installed, e.g. $HOME, /usr, /usr/local.
#
# ****************
# IMPORTANT NOTES:
# ****************
# * for compilation to succeed, you may have to execute
# $ export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:[{$PREFIX}]/lib/pkgconfig
# (where [{$PREFIX}] is the contents of the PREFIX line below, without the quotes).
# The main cause for having to execute this line is installing to e.g. PREFIX=$HOME or /usr/local,
# but it may be necessary when installing to PREFIX=/usr, if your distro doesn't store
# libraries into the standard /usr/lib path.
#
# * after successful installation, you may have to add $PREFIX/bin to $PATH,
# and $PREFIX/lib to $LD_LIBRARY_PATH, for the SVN versions of libti* and tiemu
# to get picked up.
#PREFIX="$HOME"
PREFIX="/usr"


# The place where the sources will be stored.
SRCDIR="$HOME/lpg"


# MANDATORY dependencies for compiling and running libti* and tiemu:
# (Debian and Fedora package names are given if they're different from each other)
# * (subversion - for downloading the sources)
# * 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)
#   (libusb 0.1.x preferred, but libticables now has a libusb 1.0 backend activated with "--enable-libusb10", see below)
# * 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)
# * libncurses 5 development files (libncurses5-dev, ncurses-devel)
# * GNU gettext
# * GNU bison, flex
# * GNU groff, texinfo
# * XDG utils
# * Qt 3 development headers.
#
# Optional dependencies:
# * KDE 3.x development files (kdelibs4-dev, kdelibs3-devel), if you want to compile TIEmu with support for the KDE file dialog.
#   (this implies a slew of development files, among which the Qt development files, and is therefore disabled by default)
# * DBus-Glib development files (libdbus-glib-1-dev, dbus-devel + dbus-glib-devel), if you want to compile TIEmu with D-Bus support.
