syntax errors in Python source files
by Jeremy Hylton 23 Aug '01

23 Aug '01

I just tried to build and install a distutils package using Python 1.5.2. The package uses some features added after 1.5.2 and a few files have SyntaxErrors as a result. I did a "setup.py build" and didn't get any complaints, but I did get errors when I tried the install. Does setup.py build generate .pyc files? It seems like it must not, or I should have seen errors when I did the build. If it doesn't, it seems like it should; otherwise you'll fail to catch SyntaxErrors until install time. Jeremy

Swig for Windows
by Moore, Paul 23 Aug '01

23 Aug '01

Hi, Where can I get a working version of swig (suitable for use with Python distutils) for Windows? The downloads from the web site don't work out of the box - distutils uses a -dnone argument, which they don't support, and they don't seem to find the python.swg file when run by hand - I get errors >swig -python example.i Generating wrappers for Python SWIG : Fatal error. Unable to locate python.swg. (Possible installation problem) This is just downloading and extracting to a new directory which I put into my PATH (not how I'd like to do it, but the simplest guess in the absence of any obvious installation instructions :-() Thanks, Paul

build_scripts and #!/usr/bin/env
by Andrew Kuchling 16 Aug '01

16 Aug '01

The build_scripts command changes the #! line of Python scripts to match the Python installation being used to run the setup.py script. Currently it only fixes lines of the form #!/a/b/c/python, but leaves '#!/usr/bin/env python' alone. It used to also change #!/usr/bin/env lines, but I changed that behaviour because I think it's wrong and leaves you with no way at all to install a script that uses /usr/bin/env . A bug caused by this is at http://sourceforge.net/tracker/index.php?func=detail&aid=409430&group_id=54… I think this is a silly use case, where you want pydoc to use a different Python from the default interpreter you get by running 'python', but will bow to the SIG's opinion. So, fix /usr/bin/env lines or not? --amk

Headers files
by Sophie Coon 15 Aug '01

Hi , I am pretty new with distutils and I am using it for creating source distibution of my packages. I don't understand why distutils doesn't include automatically headers files needed for extension modules ? Thanks for any feed back.

Re: [Distutils] behavior when failing to build an extension?

Ok, thanks, then there's not much for me to do, except perhaps at some point make the error message nicer: it now crashes with a nasty traceback... Btw. does really nobody have any advice on my ranlib question of a couple of days ago? Just

behavior when failing to build an extension?
by Just van Rossum 09 Aug '01

09 Aug '01

What's the intended behavior if an extension fails to build? Should it print an error message and continue, or should it stop? (On the Mac distutils currently stops, which is kindof a nuisance, so I'm tempted to "fix" it...) Just

configuration
by Robin Becker 07 Aug '01

07 Aug '01

Just v.R has been having some problems compiling a particular library that needed libart. libart has a configuration script that should properly be invoked before building the library. Are there any plans to ease the invocation of such scripts or alternatively how to I determine in python things like endianness in size, short size long size etc etc. For all I know Darwin might run on both big and little endian machines so it's wrong to rely simply on the platform for this sort of thing. -- Robin Becker

unixcompile.py, Darwin (MacOSX), ranlib?
by Just van Rossum 07 Aug '01

07 Aug '01

I've noticed that when building a static library as part of a setup.py, I have to do ranlib build/temp.<platformname>/*.a and then run "python setup.py build" again before it works. <platformname> is "darwin-1.3.7-Power Macintosh-2.1". Can anyone suggest a patch to unixcompiler.py so that ranlib is invoked under Darwin? I've seen the comment "Not many Unices required ranlib anymore", so apparently Darwin is one of these... Just

Intermediat library and sdist problem
by Sophie Coon 07 Aug '01

07 Aug '01

Hi, I am trying to write a setup.py to create a source distribution for a wrapped library. The trick is that I need to build an intermediate library and the sdist command doesn't seem to like it. Here is the setup.py that I wrote. ========================================================================================= import os, sys, string from distutils.sysconfig import get_python_inc from distutils.core import setup, Extension # key is python version : value is the correspondent python directory name versionPath = {'2.0':'python2.0', '1.5.2':'python1.5', '2.1':'python2.1'} # Where the source file for the amber library are. libamberSrcs = ['./src/binpos.c', './src/conjgrad.c', './src/memutil.c', './src/prm.c', './src/sff.c', './src/rand2.c'] # Here could be replace by sys.prefix and sys.exec_prefix. # That will be for the distribution purpose. version = string.split(sys.version)[0] depInclude = sys.exec_prefix + '/include/%s/'%versionPath[version] numInclude = sys.prefix+'/include/%s/Numeric/'%versionPath[version] shareInclude = sys.prefix+'/include/%s/'%versionPath[version] setup( name = 'amber', version = '94', description = 'Simple Force Field (SFF) package from Amber', author = "Tom Mackle, David Case", packages = [''], libraries = [('libamber', {'sources':libamberSrcs, 'include_dirs':['./src/',depInclude, numInclude, shareInclude ], 'macros':[]}, ),], ext_modules = [Extension('sffCmodule', ['sffCmodule.c',], include_dirs = ['./src/',depInclude, numInclude,shareInclude,], libraries=['libamber']) ]) ========================================================================================================================= python2.0 setup.py sdist gives me the following error message: Traceback (innermost last): File "setup.py", line 44, in ? libraries=['libamber']) File "/tsri/python/share/lib/python1.5/site-packages/distutils/core.py", line 138, in setup dist.run_commands() File "/tsri/python/share/lib/python1.5/site-packages/distutils/dist.py", line 829, in run_commands self.run_command(cmd) File "/tsri/python/share/lib/python1.5/site-packages/distutils/dist.py", line 849, in run_command cmd_obj.run() File "/tsri/python/share/lib/python1.5/site-packages/distutils/command/sdist.py", line 143, in run self.get_file_list() File "/tsri/python/share/lib/python1.5/site-packages/distutils/command/sdist.py", line 242, in get_file_list self.add_defaults() File "/tsri/python/share/lib/python1.5/site-packages/distutils/command/sdist.py", line 319, in add_defaults self.filelist.extend(build_clib.get_source_files()) File "/tsri/python/share/lib/python1.5/site-packages/distutils/cmd.py", line 107, in __getattr__ raise AttributeError, attr AttributeError: get_source_files I can very successfully run the following command: python2.0 setup.py bdist python2.0 setup.py build In the last case I have a working package that I can import from a python interpreter. I am pretty sure that the sdist command doesn't work because the intermediate library has not benn build yet when trying to do the tar ball. Did I make a mistake in the setup.py? if not is there a way around that problem? Thanks for any suggestions !
