MPI enable configuration failed in Fedora
Last modified: 2012-07-11 11:06:23 EDT
Hi Dears, Here is the code for enable MPI in file wscript. /// conf.find_program('mpic++', var='MPI') if Options.options.enable_mpi and conf.env['MPI']: p = subprocess.Popen([conf.env['MPI'], '-showme:comple'], stdout=subprocess.PIPE) flags = p.stdout.read().rstrip().split() p.wait() env.append_value("CXXFLAGS_MPI", flags) /// However, the output of bash command "mpic++ -showme:compile" is not supported in fedora14. And blocked compile error occurred list below, even I have installed mpic++. ///// Waf: Entering directory `/home/Devil/linux/project/ns-3-dev/build' [ 804/1526] cxx: src/mpi/model/distributed-simulator-impl.cc -> build/debug/src/mpi/model/distributed-simulator-impl_1.o [ 805/1526] cxx: src/mpi/model/mpi-interface.cc -> build/debug/src/mpi/model/mpi-interface_1.o ../src/mpi/model/mpi-interface.cc:37:17: fatal error: mpi.h: No such file or directory compilation terminated. ../src/mpi/model/distributed-simulator-impl.cc:35:17: fatal error: mpi.h: No such file or directory compilation terminated.

What does the command "mpic++ -showme:compile" give as output. What is its return code (echo $?) ?
And what toolset you have, lam, openmpi, libmpich? Can you try others and see if any works?
(In reply to comment #2) > And what toolset you have, lam, openmpi, libmpich? Can you try others and see > if any works? I have installed mpich2. And I removed mpich2, and tried openmpi, conf.env[] did not find the mpic++,even the mpic++ has been installed under folder "/usr/lib/openmpi/bin" I hard coded the path of mpi in wscript file of value conf.env['MPI'], and it worked, but, while running MPI related simulation, it reported libmpi_cxx.so can not found, even have add the library path to $LD_LIBRARY_PATH. That is the torment of it.
Hi Dears, Could u please provide solution for me ... I just can not fix it..
With openmpi installed, try: MPI=/usr/lib/openmpi/bin/mpic++ ./waf configure --enable-mpi
Could the reporter comment on this one again? Is this still an issue? I'm thinking about closing this one.
(In reply to comment #5) > With openmpi installed, try: > > MPI=/usr/lib/openmpi/bin/mpic++ ./waf configure --enable-mpi I just tried this on a Fedora 17 buildslave, which has openmpi-devel installed (and mpic++ in /usr/lib/openmpi/bin/mpic++). First, MPI is not auto-detected: ./waf configure --enable-mpi ------------------------------------------------------------------------- Checking for 'mpic++' ['mpic++', '-showme'] not found from /home/buildslave/ns-3-allinone/ns-3-dev/src/mpi: The configuration failed ------------------------------------------------------------------------- Checking for 'mpic++' ['mpic++', '-compile-info', '-link-info'] not found from /home/buildslave/ns-3-allinone/ns-3-dev/src/mpi: The configuration failed ------------------------------------------------------------------------- Next, Gustavo's tip above: MPI=/usr/lib/openmpi/bin/mpic++ ./waf configure --enable-mpi fails the same way.
Hello I installed Fedora 17 on a new virtual machine and grabbed a fresh copy of NS3. I then install openmpi. If I do this: export PATH=$PATH:/usr/lib64/openmpi/bin or MPI=/usr/lib64/openmpi/bin/mpic++ ./waf --enable-mpi configure I get this: MPI Support : enabled So is it a particular MPI script that isn't working or is it just a problem with installing MPI correctly?
Updated MPI documentation to show how to set PATH and LD_LIBRARY_PATH for 32 and 64 bit linux distros
