Undefined symbols during linking
Posted: 15 Feb 2024 17:47
Hello everyone!
I am trying to compile libvlc from last VLC Android sources, where I prepared manually inside vlc-android directory also libvlcjni sources on Ubuntu 20.04 with Android NDK 25.2.9519653 as asked from compile.sh procedure but, at certain moment during linker it reported this error:
and googling around I figured it's something about -fexceptions flag which should be removed to make it working but I haven't found where would this -fexceptions flag affect to this harfbuzz to make this error.... I tried also to put a -fno_exceptions flag in a Makefile where it calls for $(CXXFLAGS) but it didn't worked... do you have any suggest about it?
Thanks in advance!
Cheers!
