[zeromq-dev] Re : Massive problems running ZMQ on android

[jonas.adler at epiq.se]

I reinstalled Ubuntu (it's not my work machine, just using it to build for
android) and got a problem that the C compiler couldn't create executables
again but some searching on google i found that i needed "ia32-libs"
package because i was running a x64 ubuntu and the NDK is compiled for
32-bit.

After that 300mb package everything went just fine. I not have my zmq.jar
and libjzmq.so ! :)

So I can now confirm that it works (the compiling anyways).


But now I've come across another problem... I assume that android zmq is
identical to java, but when i tried an example (hwclient) I got a "FATAL
EXCEPTION: main, java.lang.NoClassDefFoundError: org.zeromq.ZMQ."
The only change i made to the code is "System.loadLibrary("jzmq");" at the
top.

the .jar is in /libs/ and has been added to build path and the .so is in
/libs/armeabi/

I've also added the internet permission to the android manifest.
