How can I enable running the "config" command prior to all "build" commands ?

Thanks,

Suppose your custom "config" command writes out a file "configdata". When running the install command you can check if this file exists and if not raise an exception which demands to run "python setup.py config":

class MyDistribution(Distribution): def __init__(self, attrs=None): Distribution.__init__(self, attrs=attrs) self.config_file = "configdata"

def run_commands(self):
    if "config" not in self.commands:
        if not os.path.exists(self.config_file):
            raise SystemExit, "please run 'python setup.py config'"
    Distribution.run_commands(self)

class MyConfig(config): def run(self): # ... write "configdata" file

Thanks for the example. What I was thinking of is a little different though: I have a configuration class which will do some environment testing in order to determine flags and options for the build_ext class. Now in order to have this information available before the build I need to assure that the config command is executed before the build step.

After some hacking I found that the following trick enables this:

from distutils.command.config import config from distutils.command.build import build

class autoconf(config):

def run(self):

...config code... build_ext = self.distribution.reinitialize_command('build_ext') # Set options build_ext.define = mydefines

class autoconf_build(build):

def run(self):

self.run_command('autoconf') build.run(self)

and then in setup():

cmdclass = {'autoconf': autoconf, 'build': autoconf_build},

With this setup you can execute "setup.py bdist_rpm" and the autoconf command will get executed automatically or you can run "setup.py autoconf --autoconf-option build" to pass additional options to the autoconf command.

Unfortunately, bdist_rpm doesn't seem to inherit the command options you passed to the setup.py script -- the build is done in a separate process which is invoked by RPM rather than from the original setup.py process.

Thanks,
