Compile on Windows with Python Bindings

[Adam]

I am compiling gnucash in Windows using MinGW  in order to include the
Python bindings. I have been using 2.6.14 release source code from Git.

I have arrived at step 10 in the python-bindings sections but now have 3
issues:

1) I get the following error message when attempting to run gnucash
using 'gnucash-launcher.cmd': "The procedure entry point
__gmpn_cnd_add_n could not be located in dynamic link library
C:\GCDev\gnucash\inst\bin\libhogweed-2-5.dll"
   - this happens with and without python bindings installed, when not
   installed the program starts
The error does not occur when the gnucash.exe is run directly from the
dist directory created for the installer package.

2) When python bindings are enabled, gnucash terminates with an
exception when the splash screen reaches 'gnucash/python'. This is the
best I could capture from the error logging via command line switches:
* 07:54:02  INFO <gnc.gui> [main] System locale returned English_United
Kingdom.1252
* 07:54:02  INFO <gnc.gui> [main] Effective locale set to English_United

3) With the following batch script  setup, I have run Python and
attempted to import gnucash:

SET PYTHONPATH=C:\GCDev\gnucash\inst\lib\site-packages
SET PATH=%PATH%;C:\gcdev\gnucash\inst\bin
SET PATH=%PATH%;C:\gcdev\gnome\bin
SET PATH=%PATH%;C:\gcdev\mingw\bin
SET PATH=%PATH%;C:\gcdev\regex\bin
SET PATH=%PATH%;C:\gcdev\guile\bin
SET PATH=%PATH%;C:\gcdev\libxslt\bin
SET PATH=%PATH%;C:\gcdev\libdbi\bin
SET PATH=%PATH%;C:\gcdev\mysql\lib
SET PATH=%PATH%;C:\gcdev\pgsql\bin
SET PATH=%PATH%;C:\gcdev\pgsql\lib
SET PATH=%PATH%;C:\gcdev\sqlite3\bin

python -v

This crashes python.exe with an exception and results in the following
output:

# C:\Python27\lib\encodings\cp850.pyc matches

This application has requested the Runtime to terminate it in an unusual
way.
Please contact the application's support team for more information.

Any thoughts on where I might be going wrong? Is trying to compile with
Python bindings a lost cause?

Thanks
