Some of the benefits of androgenizer are, that it filters the
contents of the automake variables you pass to it, so you don't
have to manually write only slightly different things in
Android-specific files. As you saw, some Android specific code is
still needed in the build system:
- to pass the automake variables to androgenizer, which cannot
parse automake files itself. This way we let GNU Make parse the
automake files, and androgenizer gets the final values.
- a top-level hand-written Android.mk that will execute ./configure
and everything related, and cause the androgenizer-generated
Android.mk files to be created. We have managed to create such
makefiles, that these steps get executed automatically as needed
during the full Android system build. Whenever new makefiles are
being generated, GNU Make notices that, and automatically
restarts the whole build to read them in. (This is not about
androgenizer but Android builds in general.)
Androgenizer also fixes up all the file paths to be relative to the
Android build root dir, so you don't have to mess with generating
file lists with different path prefixes for automake vs. Android
Or at least that is what androgenizer should do, it may have bugs
of course. Androgenizer is no magic tool that automatically makes
an autotools project building for Android, but it should help with
the most common pains.
I have some patches in Androgenizer, and I have androgenized few
projects for Collabora. I'd be happy to answer questions about
androgenizer. Please, use my work email (cc'd): ppaalanen at gmail.com
