lyx_mirror/development/Win32/packaging/build_lyxwin.sh

#! /bin/sh

# This script aims to do averything necessary to automate the building
# of a LyX/Win package.

# Invocation:
# sh build_lyxwin.sh "1.3.6-pre23"
# The string will be shown in the "About LyX" dialog.

# This script is written as a bunch of subroutines. You'll probably
# only need to build a couple of the packages (dtl, aspell) once.
# Thereafter, the invocation of these subroutines can be commented out.
# (See the end of the script.)

# Notes:
# It uses the MinGW/MinSYS environment and compiler.

# It asks whether the Qt and LyX cvs trees are up to date.
# It asks whether the Qt library has been compiled.
# It checks that qt-mt3.dll, libiconv-2.dll,
#   mingw10.dll and clean_dvi.py exist.
# It compiles the dv2dt and dt2dv utilites.
# It compiles and installs the Aspell library.
# It compiles and installs LyX.
# It copies the dv2dt and dt2dv utilites, the .dlls and
#   clean_dvi.py to the lyx package.
# It modifies the Resources/lyx/configure script to
#   ensure that the generated .dvi file is usable.

# Once all this is done, you're ready to "package" LyX.
# See the README for details.

# The script compiles the .dll version of the Qt libraries. Linking of lyx
# against this will, therefore, take "some time".

# It compiles the static version of the Aspell libraries because no
# .dll version exists.

# You may need to change these four variables.
