appimage.sh

#!/bin/bash

# Simple recipe to generate an appimage for this app
#
# Options:
#   * -u will upload your AppImage file after success to github under
#      "continuous builds"
#
# Requirements:
#   * VERSION as an ENV var, if not detected will use actual github
#     version + commit info
#   * This must be run after a successfully build, and need to set the
#     APP var below to the path of the executable (default is the current
#     travis build place: build/src/gqrx)
#   * Must be run on a Linux version as old as the far distro you need to
#     support, tested successfully on Ubuntu 14.04 Trusty Tar
#   * If you plan to use the "-u" option you need to configure some things
#     for it to work, check this https://github.com/probonopd/uploadtool#usage
#
# On any troubles invoke stdevPavelmc in github

# Tweak this please: this is the path of the gqrx executable relative to
#the project root will reside after build
APP="build/src/gqrx"

# No need to tweak below unless you move files on the actual project
DESKTOP="dk.gqrx.gqrx.desktop"
ICON="resources/icons/gqrx.svg"
