Hi all The zc.recipe.egg:custom recipe allows the specification of build options for a custom egg. But what do we do if we want to specify custom build options for an egg that is a dependency of a recipe (or perhaps the recipe itself)?
Case in point We have a recipe, erp5.recipe.mysqldatabase, that uses the MySQL-python. However, since we have a non-distribution installation of MySQL (we need to patch it with the Senna full text index), we need to pass compilation instructions to MySQL-python so that it actually finds the correct MySQL include and lib directories, which we do through zc.recipe.egg:custom. This works for buildout parts with recipes based on zc.recipe.egg (e.g. collective.recipe.zope2instance), even if some of the eggs mentioned depend on MySQL-python, as long as the zc.recipe.egg:custom part for MySQL-python runs first. But if the recipe itself depends on MySQL-python, we don't get the opportunity to pass custom build options to MySQL-python, since buildout will try to satisfy the recipe dependencies of all parts even before installing the zc.recipe.egg:custom part. zc.buildout has APIs [1] [2] for passing custom build options for eggs, but appart from zc.recipe.egg:custom, I couldn't find any way to use these APIs for dependencies of recipes. [1] http://pypi.python.org/pypi/zc.buildout#handling-custom-build-options-for-extensions-provided-in-source-distributions [2] http://pypi.python.org/pypi/zc.buildout#handling-custom-build-options-for-extensions-in-develop-eggs Since we can specify versions for eggs by specifying a section with version information, I was hoping that we could also specify build options somehow. Since there are many pieces of information (including environment variables). I think that we'd need a whole section for each egg. Something on the lines of: [buildout] build-options-sufix = -options ... [MySQL-python-options] # options like the ones for the zc.recipe.egg:custom recipe Is there something like this available, and I just missed it? Can something like this be implemented as a buildout extension? Cheers, Leo PS: Conversely, it would also be nice to be able to specify different "versions" sections per zc.recipe.egg part instead of a single global one, exactly so that we can compare different version combinations with a single buildout. _______________________________________________ Distutils-SIG maillist - [email protected] http://mail.python.org/mailman/listinfo/distutils-sig
