[zeromq-dev] zmq on Android via NDK

[Florian Eckerstorfer]

Yeah I followed the rules how to compile the libzmq for android, and it
worked. I get a static library. I tried to change the ./configure line, but
I always get a static library, so I think the library should work. But how
can I link it correctly in my Android Project. How can I use the prebuilt
library. 
I' using the cpp version of zmq in my android project and in the zmq.hpp
there are all the undefined references.
So in other words, what do I have to do to make the zmq.hpp ready to work in
my android project.

Then restrict yourself to the description for libzmq.so alone, nope ?
Removing --enable-static --disable-shared in the ./configure line should do
the trick maybe.
