Tentando compilar o exemplo hello_world.c do tutorial zeromq:http://zguide.zeromq.org/page:all#Ask-and-Ye-Shall-Receive Tenho certeza que tenho tudo instalado no OSX Mountain Lion.

clang -Wall hwserver.c -o hwserver

me dá um erro:

Eu não sou o mais experiente em C. Não tenho certeza se tenho certeza de estar adicionando um sinalizador de compilador para o zmq dylib ou cabeçalhos ou meu $ PATH sendo desativado.

em / usr / local / lib:

libzmq.3.dylib
libzmq.a
libzmq.dylib
libzmq.la

e em / usr / local / include:

zmq.h
zmq_utils.h

e echo $ PATH:

/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/lib/:/usr/local/include/
