ns-3-dev fails to compile on Fedora 17 alpha with GCC 4.7

It fails in emu-net-device, but Bugzilla lacks a Component for it. $ ./waf configure Setting top to : /home/vedranm/ns-3-allinone/ns-3-dev Setting out to : /home/vedranm/ns-3-allinone/ns-3-dev/build Checking for 'gcc' (c compiler) : /usr/lib64/ccache/gcc Checking for 'g++' (c++ compiler) : /usr/lib64/ccache/g++ Checking for program pkg-config : /bin/pkg-config Checking for compilation flag -Wl,--soname=foo... support : ok Checking for program python : /bin/python Checking for python version : (2, 7, 2, 'final', 0) Checking for library python2.7 in LIBDIR : yes Checking for program python2.7-config,python-config-2.7,python2.7m-config : /bin/python2.7-config Checking for header Python.h : yes Checking for compilation flag -fvisibility=hidden... support : ok Checking for compilation flag -Wno-array-bounds... support : ok Checking for pybindgen location : ../pybindgen (guessed) Python module pybindgen : ok Checking for pybindgen version : 0.15.0.797 Checking for types uint64_t and unsigned long equivalence : yes Checking for types uint64_t and unsigned long long equivalence : no Checking for the apidefs that can be used for Python bindings : gcc-LP64 Checking for internal GCC cxxabi : complete Python module pygccxml : not found Checking for click location : ../click (guessed) Checking for library dl : yes Checking for library nsclick : yes Checking for pkg-config flags for GTK_CONFIG_STORE : ok Checking for pkg-config flags for LIBXML2 : ok Checking for type uint128_t : not found Checking for type __uint128_t : yes Checking high precision time implementation : 128-bit integer Checking for header stdint.h : yes Checking for header inttypes.h : yes Checking for header sys/inttypes.h : not found Checking for header sys/types.h : yes Checking for header sys/stat.h : yes Checking for header dirent.h : yes Checking for header stdlib.h : yes Checking for header signal.h : yes Checking for header pthread.h : yes Checking for header stdint.h : yes Checking for header inttypes.h : yes Checking for header sys/inttypes.h : not found Checking for library rt : yes Checking for header netpacket/packet.h : yes Checking for NSC location : ../nsc (guessed) Checking for library dl : yes Checking for NSC supported architecture x86_64 : ok Checking for header sys/socket.h : yes Checking for header netinet/in.h : yes Checking boost includes : 1_48 Checking boost libs : ok Checking for OpenFlow location : ../openflow (guessed) Checking for library dl : yes Checking for library xml2 : yes Checking for library openflow : yes Checking for library sqlite3 : yes Checking for header linux/if_tun.h : yes Python module gtk : not found Python module goocanvas : not found Python module pygraphviz : not found Checking for program sudo : /bin/sudo Checking for program valgrind : /bin/valgrind Checking for pkg-config flags for GSL : ok Checking for compilation flag -Wno-error=deprecated-d... support : ok Checking for compilation flag -Wno-error=deprecated-d... support : ok Checking for compilation flag -fstrict-aliasing... support : ok Checking for compilation flag -fstrict-aliasing... support : ok Checking for compilation flag -Wstrict-aliasing... support : ok Checking for compilation flag -Wstrict-aliasing... support : ok Checking for program doxygen : /bin/doxygen ---- Summary of optional NS-3 features: Python Bindings : enabled Python API Scanning Support : not enabled (Missing 'pygccxml' Python module) NS-3 Click Integration : enabled GtkConfigStore : enabled XmlIo : enabled Threading Primitives : enabled Real Time Simulator : enabled Emulated Net Device : enabled Network Simulation Cradle : enabled MPI Support : not enabled (option --enable-mpi not selected) NS-3 OpenFlow Integration : enabled SQlite stats data output : enabled Tap Bridge : enabled PyViz visualizer : not enabled (Missing python modules: gtk, goocanvas, pygraphviz) Use sudo to set suid bit : not enabled (option --enable-sudo not selected) Build tests : not enabled (defaults to disabled) Build examples : not enabled (defaults to disabled) GNU Scientific Library (GSL) : enabled 'configure' finished successfully (27.498s) $ ./waf build (...)

That seems more a missing header file, or something moved from one header to another. Not in ns-3 ones, in kernel ones. Either it could be a change in some library API. Anyway, we should fix this either by making it work or by disabling emu net-devices for this configuration. I'd like more the first idea tho. Cheers, T.
Same here. It could be a bug in Fedora, of course, in that case reporting it to Red Hat is a must. If you are willing to investigate I can provide you with a SSH access to a machine running F17 alpha.
Created attachment 1350 [details] possible fix It looks like the unistd.h header file is what's missing. The attached patch seems to fix the build problem for me.
Thanks! This works for me with additional patch which I'm posting below. I will try running all the tests to see if they pass. Tomasso, does this seem OK for inclusion?
Created attachment 1351 [details] additional patch needed This adds some static casts.
Hi Tom, can this be committed?
If the patch is compatible with all the other environments (I just checked it on MacOS X), then I have no objections. T.
Tommaso, did you apply both patches or just the first one?
changesets a3a5f9215aae and c8568ed95192. I did not test on FC 17, just on a couple of the current buildslaves; feel free to reopen if issues remain.
