Source: zeromq3 Version: 4.2.1-2 Severity: serious Hello,
zeromq3 in testing is currently built without PGM support: $ apt show libzmq5 Package: libzmq5 Version: 4.2.1-2 Priority: optional Section: libs Source: zeromq3 Maintainer: Laszlo Boszormenyi (GCS) <g...@debian.org> Installed-Size: 572 kB Depends: libc6 (>= 2.14), libgcc1 (>= 1:3.0), libsodium18 (>= 0.6.0), libstdc++6 (>= 5.2) Homepage: http://www.zeromq.org/ Tag: role::shared-lib Download-Size: 189 kB APT-Manual-Installed: no APT-Sources: http://ftp.de.debian.org/debian stretch/main amd64 Packages Description: lightweight messaging kernel (shared library) And indeed, these test scripts fail: http://code.saghul.net/index.php/2011/06/25/implementing-a-pubsub-based-application-with-python-and-zeromq/ $ ./zmq-sender Traceback (most recent call last): File "./zmq-sender", line 8, in <module> socket.connect('epgm://239.192.1.1:5000') File "zmq/backend/cython/socket.pyx", line 528, in zmq.backend.cython.socket.Socket.connect (zmq/backend/cython/socket.c:5980) File "zmq/backend/cython/checkrc.pxd", line 25, in zmq.backend.cython.checkrc._check_rc (zmq/backend/cython/socket.c:8400) zmq.error.ZMQError: Protocol not supported Looking at the build logs, it seems that upstream isn't supporting --with-system-pgm anymore: https://buildd.debian.org/status/fetch.php?pkg=zeromq3&arch=i386&ver=4.2.1-2&stamp=1483291021&raw=0 ./configure --build=i686-linux-gnu --prefix=/usr --includedir=\${prefix}/include --mandir=\${prefix}/share/man --infodir=\${prefix}/share/info --sysconfdir=/etc --localstatedir=/var --disable-silent-rules --libdir=\${prefix}/lib/i386-linux-gnu --libexecdir=\${prefix}/lib/i386-linux-gnu --disable-maintainer-mode --disable-dependency-tracking --with-system-pgm --with-libsodium configure: WARNING: unrecognized options: --disable-maintainer-mode, --with-system-pgm Looking into configure.ac, it seems that it uses the system pgm library by default; however, one needs to add --with-pgm to configure options, as it's disabled by default: # build using pgm have_pgm_library="no" AC_ARG_WITH([pgm], [AS_HELP_STRING([--with-pgm], [build libzmq with PGM extension. Requires pkg-config [default=no]])], [with_pgm_ext=$withval], [with_pgm_ext=no]) # conditionally require pgm package if test "x$with_pgm_ext" != "xno"; then PKG_CHECK_MODULES([pgm], [openpgm-5.2 >= 5.2], [ have_pgm_library="yes" ], [PKG_CHECK_MODULES([pgm], [openpgm-5.1 >= 5.1], [ have_pgm_library="yes" ])]) fi if test "x$have_pgm_library" = "xyes"; then AC_DEFINE(ZMQ_HAVE_OPENPGM, [1], [Have OpenPGM extension]) PKGCFG_LIBS_PRIVATE="$PKGCFG_LIBS_PRIVATE $pgm_LIBS" fi AM_CONDITIONAL(HAVE_PGM, test "x$have_pgm_library" = "xyes") I tried replacing --with-system-pgm with --with-pgm in debian/rules and it indeed builds a libzmq5 which links to OpenPGM and in which epgm sockets work.
