Mixing pure python and extension module and multi platform
by Berthold Höllmann March 21, 2003

March 21, 2003

Hello, We have a quite large project of some quite stable extension modules and lots of frequently changing python modules. The whole thing works under Solaris and Linux. Both operating systems are accessing the same file tree using NFS. My problem now is that setup on a mixed module installes everything into the system dependent branch of the install directories. It would be nice if there is a simple customizing of the setup procedure to make setup install the extension modules into the system depending branch and the python modules into the system independent branch. Of course I can issue two "setup" commands in the setup.py, but that produces ugly results when it comes to generating binary installation packages. Regards Berthold -- Dipl.-Ing.

Installing scripts to multiple directories
by Harald Meland March 13, 2003

March 13, 2003

Hi, I'm trying to figure out how I can make distutils support installation of scripts to more than one directory, e.g. both <prefix>/bin/ and <prefix>/sbin/. I've found an open bug[1] on this in the Python project on SourceForge, but it's now over a year since the person that bug is assigned to said that he would "look at this". I started by looking through the documentation, but could not find any info on how to extend distutils. Hence, I had a look at how distutils is currently implemented, but I'm still not sure how one is meant to *properly* extend the "install*" feature set. Have anyone done this particular extension already? If not, are there any guidelines on how such an extension ought to be done? [1] Bug id 452144, viewable at http://sourceforge.net/tracker/?func=detail&atid=105470&aid=452144&group_id… -- Harald

CVS distutils & bdist_wininst
by Jp Calderone March 8, 2003

March 8, 2003

Hello the list, CVS HEAD of distutils doesn't currently seem to install misc/wininst.exe when "./setup.py install" is run. This causes bdist_wininst to fail with error: /usr/local/lib/python2.2/site-packages/distutils/command/wininst.exe: No such file or directory (It is easily rectified by copying the file into place manually.) I'm not sure if anyone was aware of this, or if it's even appropriate to report CVS bugs to the list. Apologies if this is the wrong forum.

Possible problem using disutils
by CP Hennessy March 5, 2003

March 5, 2003

Hi, Sorry if I should be sending this to a different list, but I am not sure if this is a problem with distutils or the package made from distutils. I downloaded from the site http://users.skynet.be/sbi/libxml-python/ the package libxml2-python-2.4.30.win32-py2.1.exe. However when I try to install it there is no directory listed in the "Select python installation to use" dialog ( i.e. the second window). I have Python installed as part of zope. And I even tried to set the env. variable PYTHON_HOME to my python. Python is also in my PATH. Also I cannot manually enter a path in the "Installation Directory:" field of the same window. I'm trying to install this on Windows XP. What can I do ? Thanks CPH

Re: A question on Python Distutil

Please ask Distutils questions on distutils-sig(a)python.org.

The distutils are mostly ignorant of symbolic links, because they're not portable to Windows or Mac OS.

Right, because tar preserves symlinks by default. > My questions are: > (1) Is there any way to ask distutil to treat the file as > a plain file not a link? (hopefully file by file) No, not as far as I know. I can think of two kludges that might work: * create a ZIP file instead of a tarball -- ZIP files cannot represent symlinks, so the symlink will be followed: ./setup.py sdist --formats=zip * write a wrapper for "tar" that forces the "-h" option (which I think makes tar follow symlinks) into the real tar command line > (2) What is the right approach (to your sense) > to setup a project like this? If this is a small, personal project that only you work on, you could make project_A/foo.py a hardlink to ../project_B/foo.py. Hardlinks are best avoided though -- too implicit. But I don't have any other ideas offhand. Greg -- Greg Ward <gward(a)python.net> http://www.gerg.ca/ God is omnipotent, omniscient, and omnibenevolent ---it says so right here on the label.

python-dev not installed on Unix
by Juergen Hermann March 3, 2003

March 3, 2003

Hi! This is a VERY common error that traps users regularly: distutils.errors.DistutilsPlatformError: invalid Python installation: unable to open /usr/lib/python2.2/config/Makefile (No such file or directory) Could we extend that error message by a hint on installing the python- dev .rpm/.deb? if sys.platform = "unix": msg += "\nYou probably need to install..." Ciao, Jürgen

More documentation for setup meta-data
by Richard Jones March 1, 2003

March 1, 2003

I'm trying to better document the meta-data for the distutils (and hence PyPI). I've added words to the section in the dev doc about meta-data, and would like some feedback before I post the patch to be applied. Sorry, it's in LaTeX form (until someone writes the ReST->python doc converter ;) \subsection{Additional meta-data} \label{meta-data} The setup script may include additional meta-data beyond the name and version. This information includes: \begin{tableiii}{l|l|l|c}{code}% {Meta-Data}{Description}{Value}{Notes} \lineiii{name}{the name of the package}{short string}{(1)} \lineiii{version}{the version of this release}{short string}{(1)(4)} \lineiii{author}{package author's name}{short string}{(2)} \lineiii{author_email}{email address of the package author}{email address}{(2)} \lineiii{maintainer}{package maintainer's name}{short string}{(2)} \lineiii{maintainer_email}{email address of the package maintainer}{email address}{(2)} \lineiii{home_page}{the location of the homepage for the package}{URL}{(1)} \lineiii{description}{a short, summary description of the package}{short string}{} \lineiii{long_description}{a longer description of the package}{long string}{} \lineiii{download_url}{a location where the package may be downloaded}{URL}{(3)} \lineiii{classifiers}{a list of Trove classifiers}{list of strings}{(3)} \end{tableiii} \noindent Notes: \begin{description} \item[(1)] these fields are required \item[(2)] either the author or the maintainer must be nominated \item[(3)] should not be used if your package is to be compatible with Python versions prior to 2.2.3 or 2.3. The list is available from the PyPI website. \item[(4)] it is recommended that versions take the form <major>.<minor>.<patch>[.<sub>] \item["short string"] a single line of text, not more than 200 characters \item["long string"] multiple lines of text \item["list of strings"] see below \end{description} \option{version} encoding is an art in itself. Python packages generally adhere to the version format \em{major.minor.patch}. The major number is 0 for initial, experimental releases of software. It is incremented for releases that represent major milestones in a package. The minor number is incremented when important new features are added to the package. The patch number increments when bug-fix releases are made. Additional trailing version information is sometimes used to indicate sub-releases. These are "a1,a2,...,aN" (for alpha releases, where functionality and API may change), "b1,b2,...,bN" (for beta releases, which only fix bugs) and "pr1,pr2,...,prN" (for final pre-release release testing). Some examples: \begin{description} \item[0.1.0] the first, experimental release of a package \item[1.0.1a2] the second alpha release of the first patch version of 1.0 \end{description} \option{classifiers} are specified in a python list: \begin{verbatim} setup(... classifiers = [ 'Development Status :: 4 - Beta', 'Environment :: Console', 'Environment :: Web Environment', 'Intended Audience :: End Users/Desktop', 'Intended Audience :: Developers', 'Intended Audience :: System Administrators', 'License :: OSI Approved :: Python Software Foundation License', 'Operating System :: MacOS :: MacOS X', 'Operating System :: Microsoft :: Windows', 'Operating System :: POSIX', 'Programming Language :: Python', 'Topic :: Communications :: Email', 'Topic :: Office/Business', 'Topic :: Software Development :: Bug Tracking', ], ... ) \end{verbatim} If you wish to include classifiers in your \file{setup.py} file and also wish to remain backwards-compatible with Python releases prior to 2.2.3, then you can include the following code fragment in your \file{setup.py} before the \code{setup()} call. \begin{verbatim} # patch distutils if it can't cope with the "classifiers" or # "download_url" keywords if sys.version < '2.2.3': from distutils.dist import DistributionMetadata DistributionMetadata.classifiers = None DistributionMetadata.download_url = None \end{verbatim}
