scripts/cross-build-mingw.sh

   1 #!/bin/sh
   2 # A script to automate setup and build for Windows cross-compilation
   3 #
   4 # What it does:
   5 # 1) prepare a build directory
   6 # 2) download and unpacked the dependencies
   7 #    (see http://www.gtk.org/download/win32.php)
   8 # 2.1) fixup the unpacked pkg-config file paths
   9 # 3) setup the few required paths
  10 # 4) configure with sensible options for this
  11 # 5) build
  12 # 6) install in a local directory
  13 # 7) pack the installation in a ZIP file, ready to be used
  14 #    (but does not pack the dependencies)
  15
  16 # You may change those
