Step 0 Get a fresh XP installation
----------------------------------

0.1/ Using XPhome or Pro 32bit

0.2/ Ensure the CPU supports SSE2 instruction set or better.


Step 1, dependency install
--------------------------

1.1/ install the following in sequence (accept all default options) there should be no errors !

Python 2.6.5 ... http://www.python.org/ftp/python/2.6.5/python-2.6.5.msi
pywin 214 ... http://sourceforge.net/projects/pywin32/files/pywin32/Build%20214/pywin32-214.win32-py2.6.exe/download
matplotlib 0.99.3 ... http://sourceforge.net/projects/matplotlib/files/matplotlib/matplotlib-0.99.3/matplotlib-0.99.3.win32-py2.6.exe/download
pygtk 2.16.0 ... http://ftp.gnome.org/pub/GNOME/binaries/win32/pygtk/2.16/pygtk-2.16.0.win32-py2.6.exe
pycairo 1.8.6 ... http://ftp.gnome.org/pub/GNOME/binaries/win32/pycairo/1.8/pycairo-1.8.6.win32-py2.6.exe
pyGobject 2.20.0 ... http://ftp.gnome.org/pub/GNOME/binaries/win32/pygobject/2.20/pygobject-2.20.0.win32-py2.6.exe
py2exe 0.6.9 ... http://sourceforge.net/projects/py2exe/files/py2exe/0.6.9/py2exe-0.6.9.win32-py2.6.exe/download
psycopg2 ... http://www.stickpeople.com/projects/python/win-psycopg/psycopg2-2.2.1.win32-py2.6-pg8.4.3-release.exe
(Note: stickpeople is the offical repository, not a community build)


1.2/ MySQL 

MySQL-python-1.2.3.win32-py2.6-fpdb0.20.exe ... http://www.mediafire.com/file/iodnnnznmj1/MySQL-python-1.2.3.win32-py2.6-fpdb0.20.exe

This is an intaller built from source by gimick.  There are no official mysql-python2.6 builds for windows.

Community builds are also available from some developers.  see www.codegood.com for example.


1.3/ pytz fixup to work in an executable package

pytz needs runtime access to timezone definition files.  pytz is hard-coded to search in the directory from which the pytz .py modules are being run.
In a py2exe package, this directory is actually a library.zip container file, so windows cannot find the timezone definitions, and will crash the app.

We need to make a one-line change to pytz to search in the current working directory (which is not a container), and not the application directory.
The py2exe script copies the timezone datafiles into the package folder pyfpdb/zoneinfo.

Thanks to Jeff Peck <peck.jeff <at> gmail.com> on the py2exe mailing list for documenting this problem and solution.

1.3.1/ Navigate to C:\Python26\Lib\site-packages\pytz
1.3.2/ Edit __init__.py 
1.3.3/ At line 55 replace the following line(s):

        filename = os.path.join(os.path.dirname(__file__),
                                'zoneinfo', *name_parts)

with this line:

        filename = os.path.join(os.getcwd(), 'zoneinfo', *name_parts)

1.3.4/ Save and exit



Step 2 Setup GTK
-----------------

There are quite a few GTK packages needed, and rather than install them individually, I used the official AllinOne from the GTK project.

2,1/ Create a new folder c:\GTK

2.2/ Extract the following zip file into c:\GTK

GTK+ all in one 2.20.0 ... http://ftp.gnome.org/pub/gnome/binaries/win32/gtk+/2.20/gtk+-bundle_2.20.0-20100406_win32.zip

2.3/ If everything has worked, you should have c:\GTK\bin \etc \lib \src and so on created.


Step 3 Set GTK into the PATH variable
-------------------------------------

The path for GTK isn't set by default, so need to let the o/s know where the GTK stuff is.

3.1/ Rightclick on mycomputer to show system properties
3.2/ select advanced/environment Variables
3.3/ in "system variables" NOT "user variables" do the following
3.3.1/ create a new item as name: GTK_BASEPATH value: c:\GTK
3.3.2/ edit the item "path", press home to get to the first character and insert the following text, (no quotes, including semicolon) %GTK_BASEPATH%\bin;

3.4/ to check, open command prompt and do:

dos>path  ...  system should respond with  ...   PATH=c:\GTK\bin;C:\WIN........

3.5/ Give it a spin to test (hopefully an application will start, if not, something has gone wrong)

dos> gtk-demo


Step 4 Get the fpdb GIT tree
----------------------------

4.1/ Best to take a copy to work with; following steps will assume that the fpdb folder is on the Desktop


5.3/ Install correct Numpy for this build
-----------------------------------------

Numpy needs special handling, as by default it will install an optimised version for the SSE level of your CPU (SSE3, SSE2 or noSSE).  This means that the completed package will not run on an older CPU.  

For this reason, do not just run the installer downloaded.

5.3.1/ download the package to the Desktop
 
numpy 1.4.1 ... http://sourceforge.net/projects/numpy/files/NumPy/1.4.1/numpy-1.4.1-win32-superpack-python2.6.exe/download

5.3.2/ remove any existing numpy installation

Go to the control panel and uninstall "Python2.6 numpy-1.4.1"

5.3.3/ If you are wanting to build a package which works on all CPU's, install noSSE as follows:

dos> cd Desktop
dos> numpy-1.4.1-win32-superpack-python2.6.exe /arch nosse

5.3.4/ If you are wanting to build a package which works on SSE2 and better CPU's, install SSE2 as follows:

dos> cd Desktop
dos> numpy-1.4.1-win32-superpack-python2.6.exe /arch sse2

5.3.4/ At the end of the installation, click on "show details" to confirm the installation.

For no SSE:

"Target CPU handles SSE2"
"Target CPU handles SSE3"
"nosse install (arch value: nosse)"
"Install NO SSE"
Extract: numpy-1.4.1-nosse.exe... 100%
Execute: "C:\DOCUME~1\user\LOCALS~1\Temp\numpy-1.4.1-nosse.exe"
Completed

For SSE2:

"Target CPU handles SSE2"
"Target CPU handles SSE3"
"sse2 install (arch value: sse2)"
"Install SSE 2"
Extract: numpy-1.4.1-sse2.exe... 100%
Execute: "C:\DOCUME~1\user\LOCALS~1\Temp\numpy-1.4.1-sse2.exe"
Completed


Step 6 Run py2exe to generate fpdb.exe
--------------------------------------

6.1/ Run the script to create the fpdb.exe bundle

dos> cd Desktop\fpdb\pyfpdb
dos> c:\python26\python.exe py2exe_setup.py py2exe

wait a while, watch lots of copying and whatever.

6.2/ You should next get prompted for the GTK folder.
c:\GTK

6.3/ If there are no errors reported, it has probably worked, we will test soon.

Build notes:

There is a warning about dll's not included  "umath.pyd - c:\Python26\lib\site-packages\numpy\core\umath.pyd" - reason for this is not understood at present.  (Umath is apparently included in the built package).


Step 7 not currently used
-------------------------

Has been deleted


Step 8 Drag out the completed bundle
------------------------------------

py2exe creates a new folder for the created software bundle, drag this out to the desktop for ease of working.
As far as I know you cannot rerun the build if the fpdb-yyyymmdd-exe exists in the tree, so dragging this out 
also allows the build to re-run at step 6.

8.1/ Drag Desktop\fpdb\pyfpdb\fpdb-yyyymmdd-exe to Desktop\


Step 9 Initial run
------------------

9.1/ Open the Desktop\fpdb-yyyymmdd-exe folder
9.2/ In explorer...tools...folder options...View uncheck "Hide extensions for known file types" 
9.3/ Double click run_fpdb.bat
9.4/ check the contents of pyfpdb\fpdb.exe.log, deal with any errors thrown

9.5/ hopefully, fpdb will run 
9.6/ Try out a few options, deal with any errors reported

Observe that the msvcp90.dll was provided by the python runtime package, so we don't have to install the separate package from Microsoft.  End-users will, however need the dependency.


Step 11 pruning
---------------

11.1/ The generated folder is 100+MB and can be pruned by removing the following directories:

pyfpdb/lib/glib-2.0
pyfpdb/lib/pkgconfig
pyfpdb/share/aclocal
pyfpdb/share/doc
pyfpdb/share/glib-2.0
pyfpdb/share/gtk-2.0
pyfpdb/share/gtk-doc
pyfpdb/share/locale
pyfpdb/share/man


Step 12 rename folder 
---------------------

Rename the folder to something meaningful to the community.  If you have built for NoSSE, append noSSE to the directory name.


Step 13 Compress to executable archive
--------------------------------------

13.1/ Download and install 7zip 914 ... http://sourceforge.net/projects/sevenzip/files/7-Zip/9.14/7z914.exe/download
13.2/ Rightclick on fpdb executable folder, select 7zip Add to archive... select SFX archive option switch
13.3/ Test the created exe file

Step 14 If you need to build again for a different SSE level
------------------------------------------------------------

Go back to step 5 and run again.
