zeromq / czmqpp Goto Github PK

I'm attempting to create an ebuild that will compile czmq++ on Gentoo Linux, and it currently fails with the following when attempting to build the master branch:

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

  CXX      src/certificate.lo

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.

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;
}

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.
