I would recommend to build pango by hand first. I don't think that it is
so straightforward. It has many dependencies iconv, expat, fontconfig,
freetype, glib at least. After a whole day of struggling my pango build
failed somewhere in the middle at "who-knows-where-it-comes-from" macro :(

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 ;)

Hi, I'm not familiar with the Android build process but basically this is what
you need:
Build graphics/src/main/native-font/fontpath_linux.c to a library called
"javafx_font", that it will be loaded by PrismFontFactory.java (but used by
FontConfigManager.java).
This is our fontconfig binding used to locate fonts. All references to
fontconfig in the native code are dynamic, so you should only need the JNI
references while building this object.
Build
graphics/src/main/native-font/freetype.c
and
graphics/src/main/native-font/pango.c
To a library named "javafx-font-pango"
The cc flags to build them are "pkg-config --cflags pangoft2" +
"-D_ENABLE_PANGO", the lib flags are pkg-config --libs pangoft2
(see rt/buildSrc/linux.gradle, search pangoCCFlags and pangoLinkFlags).
This library will be used by
graphics/src/main/java/com/sun/javafx/font/pango/OS.java
During runtime you will need to explicitly set "-Dprism.text=native" so that
PangoFactory.java is used (instead of T2KFactory.java).
Note: if that is too hard to build pango.o I suppose you could link
javafx-font-pango.so only with freetype.o, you should not see any unsatisfied
link exception as long as PangoFactory.createGlyphLayout is not called.
Setting -Dprism.debugfonts=true should help to see what is getting loaded,
-Djavafx.verbose=true prints what library as being loaded by JFX.
Regards,
Felipe

Is there a fallback? Pango doesn't work either it's not used in the android
gradle scripts.
I would be happy to integrate it and I am sure I can compile pango for android.
I just need a pointer to how I can integrate it into the build process.
I changed android.gradle but I am not sure where to put the pango sources.
