Please provide a tag or an archive for lua-zmq repository, possibly one with the version as numeric value in it.

assert called with required code

assert() isn't a function call, it's a macro, and calling it with side-effects is an error. See the first Warning here:

http://www.cs.utah.edu/dept/old/texinfo/glibc-manual-0.02/library_28.html

All the calls like this are bugs:

    assert(zmq_term(ctx->ptr) == 0);

After running publisher.lua and subscriber.lua for a while I see that the lua running subscriber.lua is using more and more memory. Is there something that needs to be freed somewhere or is this a genuine leak?

Thanks

Examples cliente.lua and server.lua does nothing wint zeromq 2.0.10

I've downloaded and installed zeromq 2.0.10 and the lua binding on both win32 and linux and on both I have the same reult:
client.lua and server.lua start and sit there waiting forever without any sign of life and I use ctrl-c to finish then.
Is this an issue someone else is experimenting ?

[Solved] Compiling against luajit?

I can't get the bindings to work with luajit. Tried to:

gcc -I/usr/local/include/luajit-2.0/ -o zmq.lo -c -pthread -fPIC -Wall -O2 zmq.c
gcc -shared -lzmq -lluajit-51 zmq.lo -o zmq.so

requiring zmq gives the following error:

dlopen(/usr/local/lib/lua/5.1/zmq.so, 2): Library not loaded: libluajit.so

EDIT: Additional compilation flags and prober libluajit renaming are need for Mac OS

Broken compatibility with old zmq version with e5555

ZMQ_PULL/ZMQ_PUSH are not defined in earlier zmq headers (2.0.7)

libuv example wanted

Hi!

Wonder if you could provide an example similar to https://github.com/Neopallium/lua-zmq/blob/master/examples/ev_subscriber.lua for joyent/libuv?

TIA,
--Vladimir
