building harfbuzz with freetype support symbol errors

[olymk2]

Hoping some one can help me out i have spent quite a bit of time on this and not progressed.

I/python  ( 8605):  OSError: dlopen failed: cannot locate symbol "hb_ft_font_create" referenced by "libfreetype.so"...

From googling around it sounds like this means those methods are not available in the built .so file.

however I can inspect the built files with objdump

objdump -TC libharfbuzz.so | grep hb_font_create
00013208 g    DF .text  000000ac hb_font_create
000132b4 g    DF .text  000000c0 hb_font_create_sub_font

objdump -TC libfreetype.so | grep hb_ft
00000000      D  *UND*  00000000 hb_ft_font_create

I wonder if its a case of freetype cant find harfbuzz to call the method perhaps ?
but i am delving deeper and deeper out of my knowledge level with this stuff.

any one able to lend a hand or offer some things to try ?

you can see my current branch here #378

I guess freetype know about harfbuzz and use a function declared into the harfbuzz. But Harfbuzz don't know about freetype and don't compile the needed method.

It might be due to a invalid set of flags / ordering during the compilation maybe ?

you might be right, i am still trying to figure this out when i get some time as its stopping me progressing with my app.

I have tried various different flags and different orderings, but i am stabbing around in the dark quite a bit :/

I have created a simple gist which will throw the error when loading freetype.

My current progress is below, i believe it may need the nostdinc option, i believe its building against local libraries but i can convince it to work with nostdinc option.

#378

the buildozer.spec file i am using has a hard coded py4a folder so if you use that update it.

I am testing on my device by running
buildozer android debug deploy logcat run

The harfbuzz recipe has changed a lot since this was created, please reopen if it's still a current issue causing a problem.
