zeromq / czmqpp Goto Github PK

What exactly does this library depend on? Is it simply libzmq.so/libzmq.dylib, or something else/additional?

The CZMQ v2 APIs have been declared deprecated with the 3.0.0 release in October 2014: https://github.com/zeromq/czmq#toc3-8224

Following the C4.1 process we are moving toward retiring those APIs - i.e. deleting them. This will break czmqpp.

The solution would be to update czmqpp to use the new v3 APIs from CZMQ.

I'm creating a Portfile for MacPorts. Would you mind tagging a release, even if it's preliminary? Thanks.

@evoskuil suggests a v1.1.0 tag for master HEAD.

I'm getting this error trying to build:

Hi,

I've made changes to be able to work with VS2010 (added project files and fixed compilation issues). As the VS2010 compiler doesn't implement all of the C++11 language features there's quite a few changes. The only way I can think to make it build for all platforms with be with liberal use of preprocessor definitions, making it quite a mess. Would this be better be kept as 2 separate projects?

Cheers,
Hugh

I have a test case for czmq, that I wish to port to C++/czmqpp, for inclusion in a package specification (Homebrew formula). Is there any chance someone could help me out on this? My C++ is awfully rusty, and there doesn't exist any documentation for czmqpp it seems.

#include <czmq.h>

int main(void)
{
  zsock_t *push = zsock_new_push("inproc://hello-world");
  zsock_t *pull = zsock_new_pull("inproc://hello-world");

  zstr_send(push, "Hello, World!");
  char *string = zstr_recv(pull);
  puts(string);
  zstr_free(&string);

  zsock_destroy(&pull);
  zsock_destroy(&push);

  return 0;
}
