Hi Felipe,
thanks for your fast answer.
Unfortunately, this is not enough information for a sufficient solution ;)
Maybe I am too far from gradle away in my thinking (Makefiles) to understand
this one fully.
I know where the sources are and I am pretty sure I can build a library by
hand. Actually, I added
to the android gradle script the Linux fontpango parts and the pkg-config tool.
I assume that the default linux gradle script looks for the pango libs in
/usr/share ...
(default paths). Now we are in a cross platform enviornment for Android. At
least I have to call
./configure with the android toolchain. That should not be hard to do.
What I don't know is, how do I add this to the gradle script?
I see the pkg-config in crosslibs but that relies on the assumption that pango
resides
somewhere in ${SYSROOT}.
Well, I probably could build pango (haven't tried yet) for android and put it
in the NDK,
from my point of view, that wouldn't work later at run time. The .so must be
linked and
delivered with the App. Maybe someone can enlighten me how I can integrate a
third party
library build into the gradle universe ;)
regards
Matthias
