#!/bin/bash -e

# build Subsurface for Windows
#
# this file assumes that you have installed MXE on your system
# and installed a number of dependencies as well.
#
# cd ~/src
# git clone https://github.com/mxe/mxe
# cd mxe
#
# now create a file settings.mk
#---
# # This variable controls the number of compilation processes
# # within one package ("intra-package parallelism").
# # Set to higher value if you have a powerful machine.
# JOBS := 1
#
# # This variable controls the targets that will build.
# MXE_TARGETS :=  x86_64-w64-mingw32.shared
#
# # Uncomment the next line if you want to do debug builds later
# # qtbase_CONFIGURE_OPTS=-debug-and-release
#---
# (documenting this in comments is hard... you need to remove
# the first '#' of course)
#
# now you can start the build
#
# make libxml2 libxslt libusb1 libzip libssh2 libftdi1 curl qt5 nsis
#
#     (if you intend to build Subsurface without user space FTDI support
#      you can drop libftdi1 from that list and start this script with
#      -noftdi )
#
# After quite a while (depending on your machine anywhere from 15-20
# minutes to several hours) you should have a working MXE install in
# ~/src/mxe
#
# Now this script will come in:
#
# This makes some assumption about the filesystem layout so you
# can build linux and windows build out of the same sources
# Something like this:
#
# ~/src/mxe                    <- MXE git with Qt5, automake (see above)
#      /subsurface             <- current subsurface git
#      /googlemaps             <- Google Maps plugin for QtLocation from git
#      /hidapi                 <- HIDAPI library for libdivecomputer
#
# ~/src/win32                  <- build directory
#
# then start this script from ~/src/win32
#
#  cd ~/src/win32
#  bash ../subsurface/packaging/windows/mxe-based-build.sh installer
#
# this should create the latest daily installer
#
# in order not to keep recompiling everything this script only compiles
# the other components if their directories are missing or if a "magic
# file" has been touched.
#
# so if you update one of the other libs do
#
# cd ~/src/win32
# touch build.<component>
# bash ../subsurface/packaging/windows/mxe-based-build.sh installer
#
# and that component gets rebuilt as well. E.g.
# touch build.libdivecomputer
# to rebuild libdivecomputer before you build Subsurface
#
# If you want to create a installer for the debug build call
#
#  bash ../subsurface/packaging/windows/mxe-based-build.sh debug installer
#
# please be aware of the fact that this installer will be a few 100MB large
#
#
# please send patches / additions to this file!
