#
# This script is used to build an 'AppImage' from GitHub sources of
# QPDF (see https://appimage.org/). It is used in CI, but it also
# allows Linux users to build such an AppImage on their own systems.
# Please read 'README.md' from the top level Git sources to see what
# preconditions you must meet to build QPDF in general. The same apply
# to build an AppImage. Then follow these three steps:
#
# 1. Clone Git sources: `git clone https://github.com/qpdf/qpdf.git git.qpdf`
# 2. Change into git dir: `cd git.qpdf`
# 3. Run this script: `bash appimage/build-appimage`
#
# The resulting AppImage will be placed in
# './appimage/build/QPDF-x86_64.AppImage'. Read the output of the
# script for hints in case something goes wrong.
#
# You may pass custom options for the configure step by setting them
# into the 'CUSTOM_CONFIGURE' environment variable and exporting it
# before running this script. For example:
#
# export CUSTOM_CONFIGURE=" -DSOME_OTHER_OPTION=1 [...]"
#
# ATTENTION:
#
# 1. To build the AppImage you should have a working internet
# connection. Reason: the script downloads the most recent
# 'linuxdeployqt' utility for building the AppImage.
# 2. If you build the AppImage on a too recent Linux distribution,
# it may only work on the exact distribution you build it on. For
# an AppImage to work on a wide range of different distributions
# from the last 3-4 years if should be built on the oldest
# supported Ubuntu LTS release.
