not compiling

[temoto]

I get bizarre error on compilation. Looks like missing header, but i'm not expert here.

ØMQ version (Ubuntu package from Chris Lea PPA): 2.0.7beta-1chl1~lucid1 libmq-dev package with headers is installed as well. Go version: 34c94d05958c gozero version: 7b78b4

$ make install CGOPKGPATH= /home/temoto/bin/cgo -I. -I "/home/temoto/src/go/include" zmq.go gcc failed:

There were some API changes introduced in version 2.0.7. The Go binding looks stuck with 2.0.6 version:

• The zmq_init() function now has only a single parameter; the number of 0MQ I/O threads to create in the context being initialised. The app_threads and flags parameters have been removed. ZMQ_POLL constant was thus removed.
• The ZMQ_P2P socket type has been renamed to ZMQ_PAIR.
• The ZMQ_LWM socket option has been removed; the low water mark for a socket is now computed automatically by 0MQ.
• A zmq_getsockopt() function has been added.

Thank's for reporting this. I haven't touched the code in a while - it is quite alpha. BTW I did develop this on mac snow leo against zmq 2.0.6 - no testing with 2.0.7 or under linux has been done so far! I'll likely come around to look into pushing it to compile against 2.0.07. sometime next week. In the mean time, please send patches ;-)

I found the time to make it build on 2.0.9 again; and figured out how to pass a cleanup function pointer to C (quite tricky with cgo but needed by zmq_init_msg_data)

still mostly untested and far from complete
