# uni-build-dependencies by don bright 2012. copyright assigned to
# Marius Kintel and Clifford Wolf, 2012. released under the GPL 2, or
# later, as described in the file named 'COPYING' in OpenSCAD's project root.

# This script builds most dependencies, both libraries and binary tools,
# of OpenSCAD for Linux/BSD. It is based on macosx-build-dependencies.sh
#
# By default it builds under $HOME/openscad_deps. You can alter this by
# setting the BASEDIR environment variable or with the 'out of tree'
# feature
#
# Usage:
#   cd openscad
#   . ./scripts/setenv-unibuild.sh
#   ./scripts/uni-build-dependencies.sh
#
# Out-of-tree usage:
#
#   cd somepath
#   . /path/to/openscad/scripts/setenv-unibuild.sh
#   /path/to/openscad/scripts/uni-build-dependencies.sh
#
# Prerequisites:
# - wget or curl
# - OpenGL (GL/gl.h)
# - GLU (GL/glu.h)
# - gcc
# - Qt4
#
# If your system lacks qt4, build like this:
#
#   ./scripts/uni-build-dependencies.sh qt4
#   . ./scripts/setenv-unibuild.sh #(Rerun to re-detect qt4)
#
# If your system lacks glu, gettext, or glib2, you can build them as well:
#
#   ./scripts/uni-build-dependencies.sh glu
#   ./scripts/uni-build-dependencies.sh glib2
#   ./scripts/uni-build-dependencies.sh gettext
#
# If you want to try Clang compiler (experimental, only works on linux):
#
#   . ./scripts/setenv-unibuild.sh clang
#
# If you want to try Qt5 (experimental)
#
#   . ./scripts/setenv-unibuild.sh qt5
#
