2012-05-21Issue a warning on unsupported architectures instead of failingGabriele Svelto

2012-05-12Enabled plug-in loading on all hosts with support for dlopen()Gabriele Svelto
Previously the code used for loading plug-ins would be built only on Linux hosts. Now the required functions are checked for and plug-in loading code is enabled if those are present on all platforms. Using lstat() to check for file types also increases portability to hosts that do not have the dirent.d_type field. If shared libraries support is disabled plug-ins will also be automatically disabled. Signed-off-by: Gabriele Svelto <gabriele.svelto@gmail.com>
2012-05-02Conditionally include header files required by select() and poll()Gabriele Svelto
Feature checks are introduced to check for all the headers required by the select() and poll() calls. Include files are then included conditionally without the use of any OS-specific directive. The change also fixes a couple of problems: - Fixed compilation under FreeBSD, NetBSD and OpenBSD when forcing the use of select() in the poller - Quieted a warning mixed-sign comparison warning on FreeBSD caused by FD_SETSIZE being declared as an unsigned constant on that OS - Removed the obsolescent AC_HEADER_TIME macro from the configure script Signed-off-by: Gabriele Svelto <gabriele.svelto@gmail.com>
2012-04-29atomic: revisit the atomic operation checks and their usageAndrew W. Nosenko
* configure.ac: Check for working Solaris/NetBSD-style atomic.h independly on OS. Add check for GCC-style __sync_*() builtins. New defines: XS_ATOMIC_GCC_SYNC, XS_ATOMIC_SOLARIS. Removed define: XS_FORCE_MUTEXES. * src/atomic_counter.hpp: (atomic_counter_t::add): (atomic_counter_t::sub): * src/atomic_ptr.hpp: (atomic_ptr_t::xchg): (atomic_ptr_t::cas): Use result of these checks. Preference order: 1. GCC-style __sync_*() builtins 2. Inline asm (x86, x86-64, armv7a) 3. Solaris/NetBSD-style atomic.h, Windows-specific API 4. Fallback to mutex-based implementation
2012-04-27Replaced obsolete autoconf and automake macrosGabriele Svelto
This patch cleans up a number of obsolete constructs in the build system, these include: - Replacing AC_TRY_RUN with AC_RUN_IFELSE for the SOCK_CLOEXEC test - Using AC_CONFIG_HEADERS instead of AM_CONFIG_HEADER - Using LT_INIT with the win32-dll parameter instead of the obsolete AC_PROG_LIBTOOL and AC_LIBTOOL_WIN32_DLL macros - Removing the unused and obsolete AC_TYPE_SIGNAL check - Removing the unused alloca.h header check - Replacing the deprecated INCLUDES macro with AM_CPPFLAGS Signed-off-by: Gabriele Svelto <gabriele.svelto@gmail.com>
2012-04-21Change the way the polling system is selectedGabriele Svelto
All polling systems are now checked and corresponding macros set accordingly (e.g. detection of a working poll() function will define XS_HAVE_POLL). Additionally if the user selects a specific polling system via the --with-poller switch a corresponding XS_FORCE_* macro will be defined. The select() and poll() tests now conditionally include headers which makes them more robust on various target platforms. Signed-off-by: Gabriele Svelto <gabriele.svelto@gmail.com>

2012-04-16Improve POSIX threads detection and configurationGabriele Svelto
POSIX threads support is checked using the AX_PTHREAD macro, this provides improved support and coverage of different platforms. The M4 macros are also moved into the M4 directory. Signed-off-by: Gabriele Svelto <gabriele.svelto@gmail.com>
2012-04-14Define _GNU_SOURCE in addition to the __BSD_VISIBLE on freebsd-like hostsAndrew W. Nosenko
Define _GNU_SOURCE in addition to the __BSD_VISIBLE on the freebsd-like hosts. It made in hope to cover cases and obtain the full power of underlying kernel on "hybrid" systems like Debian GNU/kFreeBSD, when GLibc (or derived) library lives on top of FreeBSD kernel. On the "real" FreeBSD it only enables getline(3), and therefore, should not hurt. * configure.ac: Define _GNU_SOURCE in addition to the __BSD_VISIBLE for cover GLibc (or derived) on top of FreeBSD kernel cases, as it is in Debian GNU/kFreeBSD case.
2012-04-04Define the XS_HAVE_* poller macros in a more robust wayGabriele Svelto
The existing code for definining the XS_HAVE_* macros for the polling mechanism may fail if the platform's `tr' command does not support the GNU syntax. Replacing the hand-made declaration with autoconf macros yields the same results on all platforms. Signed-off-by: Gabriele Svelto <gabriele.svelto@gmail.com>
2012-03-30Modified the configure.ac file according to autoconf best practicesGabriele Svelto
- Use consistent quoting in M4 macros - Use portable M4sh shell constructs where possible - More consistent indentation and line wrapping - Split lists of files or functions on multiple lines to simplify adding and removing elements from them Signed-off-by: Gabriele Svelto <gabriele.svelto@gmail.com>

2012-03-13Drop libxszmq, keep only libzmq compatibility library (--enable-libzmq)Martin Lucina
This simplifies the options for new users; either use libxs APIs or build with --enable-libzmq and get libzmq 2.1 emulation. Signed-off-by: Martin Lucina <martin@lucina.net>
