This is not a problem with compiling python extensions, this is a problem linking to the mysqlclient library.

setuptools and bdist_rpm
by Jon Nelson 08 Dec '06

08 Dec '06

I'm new to setuptools and I'm hoping to have a few questions answered. I also have some observations that may be useful, but that can come later. 1. why does setuptools bdist_rpm use --single-version-externally-managed? 2. is it possible to have setuptools write dependency information not just to requires.txt but also to setup.cfg so that RPM will be aware of the dependencies? 3. This is more of a distutils question, but, what can be done about the INSTALLED_FILES containing directories that aren't marked with %dir (this causes two problems: /all/ directories end up being created but NOT owned by the RPM, and all files /under/ that directory get included, which means they likely get included *twice* to to also being explicitly included). Sorry for the multi-issue email, I'm new at this.

I have been trying to build MySQLdb for python and A. Dustman has come to the conclusion that the minGW32 compiler that I am using will not work with a Windows ( os is Windows XP) versions of Python and MySQL. Can anyone here confirm that he is right. Is there a possible work around? Dustman suggested that I would have to compile Python and MySQL with the gcc compiler for it to work. Robert G.

Yes, but it's only possible with a crude hack at the moment. Explicitly add your new version to the beginning of sys.path, then call pkg_resources.working_set.__init__(). This will clear and reset the global working set to match the current state of sys.path.

SetupTools: In Situ Upgrading
by Alexander Michael 07 Dec '06

07 Dec '06

Once a script has started, is it possible to forcibly ignore the version of a package listed in easy-install.pth and tell pkg_resources to require a newer version that is available on the sys.path? The script actually installs the newer version using easy_install, but now I want the script to use the newer available version (and forget about the older version). Thanks for any hints, Alex By the way, it appears to me that in the EasyInstall documentation (<http://peak.telecommunity.com/DevCenter/EasyInstall>) the option --upgrade is elsewhere referred to as --update, but maybe it is my misunderstanding.

You may be thinking of the zc.buildout system, which allows you to create "recipes" (sort of like makefiles, but simpler) that can be used to install complex systems, including both eggs and non-Python software. See: http://cheeseshop.python.org/pypi/zc.buildout/ http://cheeseshop.python.org/pypi/zc.recipe.cmmi/

bdist_rpm fails due to bytecompiled modules
by Christopher Blunck 06 Dec '06

06 Dec '06

hello, i have a very basic pure-python package and script that i would like to distribute as a noarch rpm using distutils. i am using FC5 as my development platform and have prepared a setup.py that properly builds and installs my application. the first problem i have is that the bdist_rpm command results in an %install section as follows: %install python setup.py install --single-version-externally-managed --root=$RPM_BUILD_ROOT --record=INSTALLED_FILES the trouble here with that %install section is that the python modules get bytecompiled and thus turned into native code. i'd prefer for that not to happen, so i have written my own install.sh script and i provide that to my python setup.py call as follows: $ python setup.py bdist_rpm --spec-only --install-script /path/to/install.sh my install.sh passes the --optimize 0 and --no-compile arguments to distutils, resulting in no .pyc or .pyo files being installed in my RPM_BUILD_ROOT. the contents of my install.sh are as follows: python setup.py install --single-version-externally-managed --root=$RPM_BUILD_ROOT --record=INSTALLED_FILES --optimize 0 --no-compile i thought that would result in no byte compiled files but unfortunately i was wrong. i'm not sure what's causing it, but rpmbuild ends up calling brp-python-bytecompile to compile the .py files. i noticed in the ChangeLog for rpm the following: - force *.py->*.pyo byte code compilation with brp-python-bytecompile. so it appears to me as tho there is no way to assemble a noarch RPM using distutils. does that sound accurate to you all? or are those folks out there using distutils and an old version of rpm (prior to 2005) that are able to assemble noarch RPMs? -c -- WeatherNet Observations for station: home Temperature: 54.80F Pressure: 30.02in; Dew Point: 30.76F (40%) Wind: 248 at 5 mph Recorded: 17:54:59 10/25/06 (http://wsdl.wxnet.org/inquiry/binding.wsdl)

Data files and --prefix question.
by José Rui Faustino de Sousa 05 Dec '06

05 Dec '06

Hi! I am writing a package installation using distutils it is very nice but I have it two snags: setup(... data_files=[("foo",["*.data"])],\ ...) setup.py install --prefix=<prefix> a) Shouldn't the *.data syntax work for data_files as it does for package_data? b) Why does it install the data files on <prefix>/foo and not in <prefix>/share/foo like the documentation seems to imply? Everything else seems to work as advertised scripts go to <prefix>/bin packages to <prefix>/lib/python2.4/site-packages... Is it me or is it a bug? Thank you very much. Best regards, José Rui

develop egg recipe?
by Nathan R. Yergler 04 Dec '06

04 Dec '06

I'm using zc.buildout for a project that also utilizes a custom egg-info writer. I specify the egg-info writer package as a setup_requires package in setup.py. Of course, that doesn't trigger zc.buildout (er, setuptools) to install that egg when I run buildout. I could work around this by specifying two parts in buildout.cfg: first install the egg for my egg-info writer, then create a development egg for my project (which uses the egg-info writer). I'm curious if there's a way with the current recipe set to create a develop egg within a part, as opposed to just specifying "develop = ." in the [buildout] section. Thanks, Nathan

checking if external dependencies are satisfied (and aborting ow).
by Ramon Diaz-Uriarte 04 Dec '06

04 Dec '06

(Apologies for cross-posting, but since this relates to both Pylons and distutils I figured it'd be OK) Dear All, We are developing a web-based application using Pylons. Pylons itself allows for easy distribution via eggs. Our application depends on non-Python software (mainly R and a bunch of R packages). As part of the installation, we would like to run a shell script (with possibly some Python and R code in it), and verify if all R-dependencies are satisfied, and if they are not, abort the installation. Note we are not trying to get setuptools to install the R-stuff, just run a script which checks a few things. I've searched the distutils and Pylons lists and docs and I cannot find this addressed, but I think I once read about this being possible. What am I missing?
