Hi i iordanov:
I am also trying to build bVNC. Everything goes well, except the
dependencies. For example:
"/bVNC/jni/src/channel-record.c:416:57: error: 'celt_int16_t' undeclared
(first use in this function)" I've already ported 0.11.1 to android, and
things like glib(Port glib: http://qinchuan.me/article.php?id=62) and so
on. But,
what the version of celt you used?
If you have time, please make a list showing the versions of the libraries.
That will be a great help!
Thanks!
