[zeromq-dev] zmq on Android via NDK

[Victor Perron]

Well I had designed a collection of scripts to automate that process, maybe
you could find some inspiration there.
https://github.com/vperron/android-jzeromq
As a matter of fact those scripts are mostly useful to remember the exact
compilation flags you need to have all the symbols resolved right, which
seems to be your issue.
I wasn't using those 'Android-specific'  NDK makefiles though, was more
relying on the generated standalone ARM toolchain and using standard
autotools for the rest.
Good luck,
