I also noticed that using cerbero（git master ）cross-compilation android armv7, the following files : libgio-2.0.a/libz.a/libgmodule-2.0.a/libgobject-2.0.a/libglib-2.0.a will not be generated（.la,.so are generated),Does anyone know why? --- clang: error: no such file or directory: '/home/shakin/work/src/ssc/gstreamer/gst-sdk/gstreamer-1.0-android-armv7-1.15.0.1/lib/libgio-2.0.a' clang: error: no such file or directory: '/home/shakin/work/src/ssc/gstreamer/gst-sdk/gstreamer-1.0-android-armv7-1.15.0.1/lib/libz.a' clang: error: no such file or directory: '/home/shakin/work/src/ssc/gstreamer/gst-sdk/gstreamer-1.0-android-armv7-1.15.0.1/lib/libgmodule-2.0.a' clang: error: no such file or directory: '/home/shakin/work/src/ssc/gstreamer/gst-sdk/gstreamer-1.0-android-armv7-1.15.0.1/lib/libgobject-2.0.a' clang: error: no such file or directory: '/home/shakin/work/src/ssc/gstreamer/gst-sdk/gstreamer-1.0-android-armv7-1.15.0.1/lib/libglib-2.0.a'
The reason why the above .a files are not generated seems I remove '-Os' in cerbero/config/android.config. To have the right symbols for debug, sometimes we do need to remove the optimization, and do not know what causality is between this. :(
Confirming that the android build is broken in git master as at 056e448d6a25ebf0d8af71978172d91054b730d4 Adding os.environ['WINDRES']= "" to config/android.cbc gets past the first error, but breaks building glib because the values assigned to CFLAGS in the recipe don't get passed to the cross compiler values - in particular not having '-DNVALGRIND=1' doesn't compile, but the GIO settings are also probably important. Adding -DNVALGRIND=1 to the c_args fixes the first part of that. Beyond that, zlib and glib are building dynamic libs, not static ones. The output won't be useful.

You should set self.meson_default_library instead.
