|
# 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.
