| [00:34] novas0x2a | is there an example for how to use zmq_poll properly? This code (where i think i'm using it right?) crashes reliably: http://codepad.org/uyAlBSOw |
| [00:35] novas0x2a | oh wow, i'm lame... ignore that code for a sec.. |
| [08:09] CIA-20 | zeromq2: 03Ilja Golshtein 07master * r4482dd7 10/ (AUTHORS include/zmq.hpp): C++ binding destructors don't throw exceptions - http://bit.ly/9r4bo6 |
| [14:07] llasm | hi !! |
| [14:10] sustrik | llasm: hi |
| [14:51] llasm | how to install zmq* |
| [14:51] llasm | i need a tuto |
| [14:53] keffo | define 'install'? |
| [14:55] pieterh | llasm: read http://www.zeromq.com |
| [14:55] pieterh | please tell me if anything is missing or unclear on the instructions there |
| [15:27] llasm | pieterh: i follow this instructions |
| [15:27] llasm | http://www.zeromq.org/bindings:python |
| [15:28] llasm | but when try python -c "import zmq" |
| [15:28] llasm | i receive cannot import name _zmq |
| [15:29] pieterh | llasm: ok, you need to also build the Python API |
| [15:29] pieterh | that is explained here: http://www.zeromq.org/bindings:python |
| [15:30] pieterh | did you install 0MQ into system libraries ('sudo make install')? |
| [15:31] pieterh | then you have to specify the system libraries in setup.cfg before doing 'python setup.py install' |
| [15:32] llasm | yes i use this command 'make install' with root user |
| [15:33] pieterh | what does your setup.cfg contain? |
| [15:33] llasm | but i don't find zeromq2-dev folder in /user/local/ |
| [15:34] sustrik | there's no such folder |
| [15:34] sustrik | you should see /user/local/include/zmq.h for example |
| [15:35] friendshi | llasm: see the section titled 'Linux' under 'Building and installation' on this page: http://github.com/zeromq/pyzmq |
| [15:37] llasm | my setup.cfg contain |
| [15:37] llasm | library_dirs = /usr/local/zeromq-dev/lib |
| [15:37] llasm | include_dirs = /usr/local/zeromq-dev/include |
| [15:38] friendshi | try this: python setup.py build_ext --rpath=/usr/local/zeromq-dev/lib --inplace |
| [15:39] friendshi | if /usr/local/zeromq-dev/lib is where you actually installed zeromq library |
| [15:40] pieterh | llasm: this is a common mistake, the example setup.cfg is confusing |
| [15:40] pieterh | edit it so that the paths are /usr/local/lib and /usr/local/include |
| [15:42] sustrik | where's the example? |
| [15:43] pieterh | setup.cfg.template |
| [15:43] sustrik | pyzmq project? |
| [15:43] pieterh | yes |
| [15:43] pieterh | i'm making a quickstarter for Python on the www.zeromq.com download page |
| [15:44] sustrik | ok, let me create a ticket asking to change the example |
| [15:44] pieterh | ack |
| [15:44] llasm | i think that the installation is ok. so i've this error when i try : python -c 'import zmq' |
| [15:44] llasm | ImportError: libzmq.so.0: cannot open shared object file: No such file or directory |
| [15:44] pieterh | also the page should not IMO tell the user to get the zeromq git |
| [15:44] llasm | is normal? |
| [15:44] pieterh | llasm: after zeromq install, 'sudo ldconfig' |
| [15:45] pieterh | that is covered here: http://www.zeromq.com/page:get-the-software |
| [15:45] friendshi | thats the error i was getting before doing the build_ext part from the documentation |
| [15:46] pieterh | friendshi, ah, thanks |
| [15:47] friendshi | see here i think: http://blog.boxedice.com/2010/05/23/building-zeromq-and-pyzmq-on-red-hat/#comment-1008 |
| [15:52] llasm | i excute 'ldconfig' but i receive the same error |
| [15:53] sustrik | is there zmq.h in /usr/local/include? |
| [15:55] llasm | yes |
| [15:55] pieterh | llasm: did you run 'sudo python setup.py install' again? |
| [15:56] llasm | yes |
| [16:00] sustrik | how does you setup.py look like? |
| [16:04] mato | 17:37 < llasm> my setup.cfg contain |
| [16:04] mato | 17:37 < llasm> library_dirs = /usr/local/zeromq-dev/lib |
| [16:04] mato | 17:37 < llasm> include_dirs = /usr/local/zeromq-dev/include |
| [16:04] mato | this would be a problem |
| [16:05] mato | /usr/local/zeromq-dev will not be in a default LD_LIBRARY_PATH |
| [16:05] mato | don't do that :-) |
| [16:05] mato | if you want things to just work then install everything in /usr/local |
| [16:05] mato | or edit your ld.so.conf / LD_LIBRARY_PATH but normally you don't want to do that |
| [16:24] llasm | LD_LIBRARY_PATH is empty. it's normal?!! |
| [16:25] guido_g | yes |
| [16:26] llasm | ok |
| [16:28] sustrik | have you changed the setup.py? |
| [16:28] sustrik | it should look like this: |
| [16:29] sustrik | library_dirs = /usr/local/lib |
| [16:29] sustrik | include_dirs = /usr/local/include |
| [16:29] ntelford | hi guys |
| [16:30] ntelford | just having a dig around the Java API and I'm wondering if there's any support for streaming very large messages without having to buffer them in local memory first? |
| [16:30] ntelford | I ask because Socket.send(byte[] msg, long flags) requires the message to be buffered as a byte array first |
| [16:38] llasm | i change my setup.py to http://friendpaste.com/661JDgQHrVJPL28tT3hma0 |
| [23:40] novas0x2a | could someone confirm that I'm using zmq_poll correctly here? http://codepad.org/iJuspYER I reliably get an uninitialized/corrupted message back out. I'm suspecting a zmq bug, but I'd like to rule out user error. |
