[zeromq-dev] ZeroMQ for Android: Problem in building the Android APK

[Victor Perron]

I thought, not use 'assign'. But the issue has been reported and discussed
in the Zeromq dev list.
I changed the Wiki today; you should stick to 2.2 for now, because a proper
fix is out of quick reach with 3.x .

It's either a lot of changes in the instructions in order to make zeromq
use stlport library, or get rid of the STL functions almost entirely.
Even using the STL has very little chances to succeed and will need heavy
patches to zeromq, would it only be for the headers inclusion; but I'm also
unsure that everything zeromq uses is defined by stlport.
Moreover, stlport is beta, so it's quite dangerous to rely on it.

I'd appreciate if somebody really involved into libzmq 3.x core could
comment about this...
