# This file is part of MXE.
# See index.html for further information.

## This set of rules is intended for building the latest released
## version of Octave found on ftp.gnu.org using the current
## packages found in the mxe-octave archive.  To reproduce the binary
## builds for Windows that are distributed on ftp.gnu.org, you must
## choose the revision of mxe-octave that matches the release you
## wish to reproduce.  Those should be tagged in the mxe-octave archive
## with tags like "octave-release-5.1.0".  The options used to build are
##
##   --enable-octave=release
##   --enable-binary-packages
##   --enable-devel-tools
##   --enable-qt5
##   --disable-system-opengl
##
## and one of the following
##
##   * 64-bit Windows build; 32-bit integers for Fortran
##     (including BLAS and LAPACK libraries) which is the typical
##     configuration for all Linux distributions:
##
##       --enable-windows-64 --enable-64 --disable-fortran-int64
##
##   * 64-bit Windows build; 64-bit integers for Fortran
##     (including BLAS and LAPACK libraries):
##
##       --enable-windows-64 --enable-64 --enable-fortran-int64
##
##   * 32-bit Windows build:
##
##       --disable-windows-64 --disable-64 --disable-fortran-int64
