# Description:
# set_soenv generates a file that contains all necessary
# environment variables for the build proces of OpenOffice
# on Linux, NetBSD, Solaris, Windows, Mac OS X and iOS.
#
# Program steps.
#
# I.    Checking the command-line arguments.
# IIa.  Declaring variables for the system commands, etc.
# IIb.  Declaring the environment variables.
# III.  Initialising the variables for the system commands, etc.
# IV.   Print out some important messages etc.
# V.    Initialising the environment variables.
# VI.   Open the output file.
# VII.  Writing the data to the output file.
# VIII. Closing output file.

WARNING:
Your make version is known to be horribly slow, and hard to debug
problems with. To get a reasonably functional make please do:

to install a pre-compiled binary make for cygwin

mkdir -p /opt/lo/bin
cd /opt/lo/bin
wget http://dev-www.libreoffice.org/bin/cygwin/make
chmod +x make

to install from source:
place yourself in a working directory of you choice.

git clone git://anongit.freedesktop.org/libreoffice/contrib/dev-tools
cd dev-tools/make-3.82-gbuild
./configure --prefix=/opt/lo
make
sudo make install

Then re-run autogen.sh

Note: autogen.sh will try to use /opt/lo/bin/make if the environment variable GNUMAKE is not already defined.
Alternatively, you can install the 'new' make where ever you want and make sure that `which make` finds it.
