Hi there,
I'm trying to induce zc.buildout's zc.recipe.egg:custom recipe to build a library (lxml) against C libraries (libxml2, libxslt) installed in a custom place, i.e. as parts, such as parts/libxml2/include and parts/libxml2/lib.
I thought I had that working before and even blogged about it, but it turns out that something's not entirely right yet.
Right now I'm struggling to actually see an 'include-dirs' directive to have any effect on what's passed along to the C-compiler (namely the -I) option. It doesn't. After some research I think I've figured out why. I've installed lxml as a development egg, and somehow it always gets built the default way. The custom egg's install code is reached, but only when it's too late and lxml is already built. Therefore any special options such as include-dirs and library-dirs are never passed, as lxml has already been created.
I figure lxml gets created automatically and not through the custom recipe as I have it listed as a develop egg in the [buildout] section.
What to do about this?
Regards,
Martijn
