Introduction

Please look for options at http://pypi.python.org/pypi/minitage.recipe.common

The egg has those entry point:

• cmmi: install configure/make/make install softwares

The reasons why i have rewrite yet another buildout recipes builder are:

• Support for downloading stuff

• Support on the fly patchs for eggs and other distribution.

• Support multiple hooks at each stage of the build system.

• Robust offline mode

• support automaticly minitage dependencies and rpath linking.

You can browse the code on minitage’s following resources:

• https://github.com/minitage/minitage.recipe.cmmi

You can migrate your buldouts without any effort with buildout.minitagificator:

minitage.recipe.cmmi

Abstract

• The cmmi recipe use abusivly or -rpath to save you from settings LD_LIBRARY_PATH at run time.

• If you are inside a minitage environment, all the dependencies of your minibuild are put in the environment. That mean that CFLAGS, LDFLAGS, PKG_CONFIG_PATH, and so on are updated to reference your minibuild’s dependencies.

• minitage.recipe.cmmi is a replacment fo zc.recipe.cmmi.

• It intends to do the configure && make && make install dance with hooks where you can do (in python) specific stuff at each stage of the build cursus.

• With this recipe, if the destination directory exists, we only remove it when we can sucessfully install something, unless that we never touch to it, or it is a bug.

• LOOK ALSO AT THE SHARED VARIABLES AS ALL THE MINITAGE RECIPES SHARE A LOT OF VARIABLES

Specific options

Please look for options at : http://pypi.python.org/pypi/minitage.recipe.common#options-shared-by-all-the-recipes

• make-targets(-UNAME)

  default to all and install, make targets to run

• inner-dir: change to inner directory before doing anything.

• prefix: where to install (defaults to options:location) Be warn that the content of the destination will be wiped before unless you set ‘install-in-place’

• install-in-place: install over a previous installation instead of removing the older install replacing it with the new ‘makeinstall result’:

  install-in-place=True

• build-dir(-UNAME)

  inner directory to execute the build dance [see cmmi recipe for documentation]

• configure-options(-UNAME)

  Os specific options to give to configure uname can be either linux2|freebsd6|freebsd7|darwin|leopard|snowleopard (darwin for both leopard) Its the result of sys.platform.lower() [see cmmi recipe for documentation]

• configure(-UNAME)

  • specific OS configure script to use (darwin, leopard, snowleopard, linux, freebsd, freebsd(6,7,8) configure script to use (default to ./configure)

• prefix-separator [see cmmi recipe for documentation]

  prefix separator to use between –prefix and location (default to =)

• prefix-option [see cmmi recipe for documentation]

  what to put for the “prefix” expression, default to –prefix$PREFIX_SEPARATOR$LOCATION

• autogen

  autogen script to use if any [optionnal]

• configure-options(-UNAME)

  options to feed configure with [see cmmi recipe for documentation]

• configure-options(-UNAME)-replace

  • overide options for a specific OS

• extra_options

  appendended to configure-options [see cmmi recipe for documentation]

• mingw

  For windows/cygwin use only Set this variable (mingw=true for example) to use mingw compiler Default will search for a mingw installation in /minitageprefix/mingw

• mingw-path

  Alternative path for mingw installation

• noconfigure(-UNAME)

  do not run ./configure

• nomake(-UNAME)

  do not run make

• noinstall(-UNAME)

  do not run make install

• make-options(-UNAME)

  options to prepent betwenn make and the target (eg MAKE

• make-install-append-options(-UNAME)

  if set, instead of prepending option before target, we will append them at install time

• make-install-options(-UNAME)

  options to append after the install targets (eg make install DESDIR=foo)

• hooks

  A hook is in the form /path/to/hook:CALLABLE:

  myhook=${buildout:directory}/toto.py:foo

  Where we have toto.py:

  def foo(options, buildout):
      return 'Hourray'

  The complete possible hooks list:

  • pre-unpack-hook

    hook executed before the unpack dance

  • post-unpack-hook

    hook executed after the unpack dance

  • post-unpack-hook

    hook executed after the unpack dance

  • pre-configure-hook

    hook executed before the configure is run

  • pre-make-hook

    hook executed before the first make target is run

  • post-build-hook

    hook executed after the build make targets are done

  • pending-make-install

    hook executed after the make and before the make install is done.

  • post-make-hook

    hook executed after the make install is done

Detailled documentation

Let’s create a buildout configuration file.

>>> rmdir(tempdir)
>>> mkdir(tempdir)
>>> cd(tempdir)
>>> a = [mkdir(d) for d in ('eggs', 'develop-eggs', 'bin', 'src')]
>>> install_develop_eggs(['minitage.recipe.cmmi'])
>>> install_eggs_from_pathes(['zc.buildout'], sys.path)
>>> touch('buildout.cfg')
>>> sh('buildout -o bootstrap')
buildout -o bootstrap...

This first buildout is classical, trying to build some url.

>>> touch('buildout.cfg',

This first buildout does nothing except print us the hooks calls. We have desactivated the configure and make dance!.

cp foo/Makefile foo/Makefile.old
>>> sh('echo >> foo/Makefile')
echo >> foo/Makefile

Using hooks

But now that we have some sort of messy packages, can we not intercale some python to code to arrange things upside down ? We have hooks to achieve that. A hook is a python callable which takes at least the options part and the buildout.

>>> data = """
... [buildout]
... download-cache=${buildout:directory}
... parts =
...     part
... [part]

... pre-configure-hook = ${buildout:directory}/hooks.py:pre_configure_hook
... pre-make-hook      = ${buildout:directory}/hooks.py:pre_make_hook
... post-build-hook    = ${buildout:directory}/hooks.py:post_build_hook
... post-make-hook     = ${buildout:directory}/hooks.py:post_make_hook
... """
>>> touch('hooks.py', data="""
... def  pre_unpack_hook    (o, b, hook='pre_unpack_hook'):

... def  post_unpack_hook   (o, b, hook='post_unpack_hook'):

... def  pre_configure_hook (o, b, hook='pre_configure_hook'):

MD5 check

Can we check md5, of course! As we have already the foo package in our download cache, we try to download something else.

>>> shutil.copy2('foo.tgz', 'bar.tgz')
>>> data = """

Controlling configure

Giving configure options the two possible ways.

>>> data = """
... [buildout]
... download-cache=${buildout:directory}
... parts =
...     part
... [part]
... recipe=minitage.recipe.cmmi

configure --prefix=/tmp/buildout.test/parts/part foo bar ...

Use OS Specific rules

Giving os specific rules.

>>> data = """
... [buildout]
... download-cache=${buildout:directory}
... parts =
...     part
... [part]
... recipe=minitage.recipe.cmmi
... url = file://${buildout:directory}/foo.tgz

Or, in the same manner, you can specify OS specific patches: (darwin, linux, freebsd6, freebsd7). sys.platform is your friend :) (‘linux’, for all linuxes).

>>> data = """

Using underlying minitage environment

If you are in a minitage, all your minibuild dependencies come automaticly in the env, no need to do the following code :) As you can have CFLAGS and so on added to your env., you can specify manual things too, the underlying code is the same. The goal is to proove that all is preprended as we would have think. We will use some hook to print the relevant parts.

>>> data = """
... [buildout]
... download-cache=${buildout:directory}
... parts =
...     part

... recipe=minitage.recipe.cmmi

Playing with the environment

You can play also with the environment directly in two ways.

• Precising a buildout part

  >>> data = """
  ... [buildout]
  ... download-cache=${buildout:directory}
  ... parts =
  ...     part
  ... [foo]
  ... CFLAGS=bar
  ... [part]
  ... recipe=minitage.recipe.cmmi
  ... url = file://${buildout:directory}/foo.tgz
  ... pre-make-hook    = ${buildout:directory}/hooks.py:pre_unpack_hook
  ... environment = foo
  ... noconfigure = true
  ... nomake = true
  ... noinstall = true
  ... """
  >>> touch('buildout.cfg', data=data)
  >>> sh('bin/buildout -o install part')
  bi...
  ('CFLAGS', 'bar')...
  

• Entering an option formed by key=value pair

  >>> data = """
  ... [buildout]
  ... download-cache=${buildout:directory}
  ... parts =
  ...     part
  ... [part]
  ... recipe=minitage.recipe.cmmi
  ... url = file://${buildout:directory}/foo.tgz
  ... pre-make-hook    = ${buildout:directory}/hooks.py:pre_unpack_hook
  ... noconfigure = true
  ... nomake = true
  ... noinstall = true
  ... environment=
  ...     CFLAGS=myvalue
  ... """
  >>> touch('buildout.cfg', data=data)
  >>> sh('bin/buildout -o install part')
   bin/buildout -o install part...
   minitage.recipe: Executing pre-make-hook
   ('CFLAGS', 'myvalue')...
  

Autogen can be your friend

It is possible to autogenerate the configure files.

>>> data = """
... [buildout]
... download-cache=${buildout:directory}
... parts =
...     part
... [part]
... recipe=minitage.recipe.cmmi
