#!/bin/bash
#
# this should be run from the src directory which contains the subsurface
# directory; the layout should look like this:
# .../src/subsurface
#
# the script will build Subsurface and libdivecomputer (plus some other
# dependencies if requestsed) from source.
#
# it installs the libraries and subsurface in the install-root subdirectory
# of the current directory (except on Mac where the Subsurface.app ends up
# in subsurface/build)
#
# by default it puts the build folders in
# ./subsurface/libdivecomputer/build (libdivecomputer build)
# ./subsurface/build                  (desktop build)
# ./subsurface/build-mobile           (mobile build)
# ./subsurface/build-downloader       (headless downloader build)
#
# there is basic support for building from a shared directory, e.g., with
# one subsurface source tree on a host computer, accessed from multiple
# VMs as well as the host to build without stepping on each other - the
# one exception is running autotools for libdiveconputer which has to
# happen in the shared libdivecomputer folder
# one way to achieve this is to have ./subsurface be a symlink; in that
# case the build directories are libdivecomputer/build, build, build-mobile
# alternatively a build prefix can be explicitly given with -build-prefix
# that build prefix is directly pre-pended to the destinations mentioned
# above - if this is a directory, it needs to end with '/'

# don't keep going if we run into an error
set -e

# create a log file of the build
