OK. The libstdc++ shared object from the NDK defines very few symbols, around twenty, mostly for what google claims to support: exceptions and such. In order to use the STL, one must use their "stlport" beta library which I believe is included since NDKr5. The shared object is present on my SGSIII, but I think that maybe it's better to statically include the needed symbols in libzmq to prevent future issues (and as long as it's in beta and that older devices mat use it)
The other way to go would be to remove all those STL calls from libzmq (as 2.2 was doing) but... ;) Thing is, I'm afraid that those functions you reported not found are not even in Android's stlport. And I'm not happy yo use another, third-party C library. I'll update the wiki about this issue, and I think you should stick to zeromq2.2 before that; that one has been properly tested as working on Android.
