Thanks. I had installed python 2.4, but went back to 2.3.2 for a reason I can't remember now. I think some other module I was using wasn't built for it yet (MySQLdb maybe?) I'll reinstall and try again. I looked at the python/typemaps.i file. I may be able to use that to redefine the functions I'm calling after I include the libraries header files to define everything else. -----Original Message----- From: Lars Immisch [mailto:lars@ibp.de] Sent: Wednesday, March 16, 2005 4:27 PM To: timothy.williams(a)nvl.army.mil Subject: Re: [Distutils] How do I modify the swig options in my setup.py > I tried using swig_opts, but it didn't recognize it.

I should have mentioned that from the start: The swig_opts extension only made it into Python 2.4b1, so you either need to upgrade Python or at least the version of distutils. > I read over the typemaps some, but the libraries I'm trying to use have gobs > of typedefs in them, and I was hoping that the #include files for the > library would take care of it.

There are no hard and fast recommendations I would want to give, except reading typemap code, experimenting, and reading the resulting C code to get a feel how swig works. Failing that, do create a minimal example of an entire interface file that shows your problem and send it to the swig mailing list. I am sure that someone will help you there. - Lars

Wrong typemaps ;-) This sort of question is best asked with a minimal example on the swig mailing list, but do have a look into typemaps in the documentation. A lot of useful typemaps are in python/typemaps.i. - Lars

How do I modify the swig options in my setup.py
by Williams, Timothy J Mr RDECOM CERDEC NVESD March 16, 2005

March 16, 2005

I'm trying to use SWIG to create an extension to access some third party libraries I want to be able to change the options to include possible '-includeall', '-c++'. I'm using distutils, but I don't know how to change from the default options. Also, a SWIG question: i build my _module.so and module_wrap.o, but when I try to call one of the functions, I get and error saying that the last argument was expected to be a pointer, but it isn't. I tried calling a couple of functions and both times SWIG is expecting the last arg to be a pointer. Any ideas? Thanks. ---- Tim Williams

distutils setup ignoring scripts
by jao＠geophile.com March 15, 2005

March 15, 2005

I'm using Python 2.2 on RH9. I have a set of Python modules organized into a root package and one other package named foobar. setup.py looks like this: from distutils.core import setup setup( name = 'foobar', version = '0.3', description = 'Foo Bar', author = 'Jack Orenstein', author_email = 'jao(a)geophile.com', packages = ['', 'xyz'], scripts = ['bin/foobar'] ) The resulting package has everything in the specified directories, but does not include the script. I've tried making the path bin/foobar absolute, but that doesn't help. I've googled for known bugs of this sort but have come up emtpy. (The first line of bin/foobar is #!/usr/bin/python.) I've also tried using DISTUTIL_DEBUG, which has been uninformative, (e.g. no mention of bin/foobar at all). Can anyone see what I'm doing wrong?
