Compiling gVim with Python 3 support

I hope this is the right place to ask this question:

I am trying to compile gVim with python 3 support using cygwin under windows:

I changed the Make_cyg.mak files Python section to the following:

##############################
# DYNAMIC_PYTHON=yes works.
# DYNAMIC_PYTHON=no does not (unresolved externals on link).
##############################
ifdef PYTHON
DEFINES += -DFEAT_PYTHON
INCLUDES += -I$(PYTHON)/include
EXTRA_OBJS += $(OUTDIR)/if_python.o

ifndef DYNAMIC_PYTHON
DYNAMIC_PYTHON = yes
endif

ifndef PYTHON_VER
PYTHON_VER = 30
endif

ifeq (yes, $(DYNAMIC_PYTHON))
DEFINES += -DDYNAMIC_PYTHON -DDYNAMIC_PYTHON_DLL=\"python$(PYTHON_VER).dll\"
else
EXTRA_LIBS += $(PYTHON)/libs/python$(PYTHON_VER).lib
endif
endif

However when running:

$ make -f Make_cyg.mak OLE=Yes PYTHON=/cygdrive/p/Applications/PortablePython_1.1_py3.0.1/App/ RUBY=/cygdrive/c/Programme/Ruby/

this results in the following errors:

In file included from /cygdrive/p/Applications/PortablePython_1.1_py3.0.1/App//i
nclude/Python.h:70,
                 from if_python.c:43:

if_python.c:2356: error: structure has no member named `ob_type'
make: *** [gobj/if_python.o] Error 1

I am using a portable python install from Portable Python. I don't know if that may be the source of the error.

I am hoping someone knows how to compile vim with python 3 support (if I only compile it with ruby support it compiles nicely).

Thanks in advance,

Gjallar

I have compiled vim with python3 support. Here is the Patch updated for vim 7.2.411.

For compilation instruction check out my 2009 September 22 mail on

groups.google.com/group/vim_dev/browse_frm/month/2009-09

(adding a second hyperlink didn't work)

There is a lot of things going on at once here. First of all, why do you want Python 3.0? If you really want Python 3, then you should use Python 3.1.

Second of all, what does "Python 3 support" mean in the case of gVim? Is it to make extensions with Python? Then you don't want Python 3 support, as any extension that exists for gVim is going to be written for Python 2.

And yeah, it seems very strange to use portable python. Since you are compiling gVim with cygwin, you should reasonably use a Python compiled with the same Cygwin.

Doesn't the normal gvim for Windows have Python support?
