[Error] OmNet not working after upgrade to OS X Lion - libmpi_cxx.0.dylib is missing

[kamuro]

Hello,

I installed OmNet several weeks ago under OS X Snow Leopard. After the
upgrade to OS X Lion I encounter problems.

I installed XCode and tried to run a simulation via Terminal.

Following error is appearing:
dyld: Library not loaded: /usr/lib/libmpi_cxx.0.dylib
Referenced from: /Users/Michael/Dev/omnetpp/omnetpp-4.1/lib/
liboppsimd.dylib
Reason: image not found
Trace/BPT trap: 5

I traced the problem back to probably missing Open MPI libraries. I
found this Portuguese article but Google translate is only little
help:
http://www.othonbatista.com/index.php/doutorado/34-compilacao-do-omnet-41-no-mac-os-x-lion

I don't get the install instructions, but I tried to install Open MPI
via MacPorts. But the install is crashing and the massive log file is
no help to me.

So, am I the only one having problems after upgrading to OS X Lion?

Best regards,

Michael

Well I did some further research and could solve that problem
(partly). The compiler has to be changed.

This post describes the task -> http://lists.macosforge.org/pipermail/macports-dev/2011-July/015263.html

And this one details it on Open MPI -> https://trac.macports.org/ticket/30330

In short adding

if {${configure.compiler} == "llvm-gcc-4.2"} {

configure.compiler clang

}

at the end to the file
/opt/local/var/macports/sources/rsync.macports.org/release/ports/
science/openmpi/Portfile

let's build it properly.

But the library does not appear in /usr/lib/...

Hi Michael,

I have the same problem. Does it mean that I have to use MacPorts and can not use OMNeT anymore directly?

Best regards,

Gürkan

I used MacPorts only to install Open MPI. The install finally worked
but the libraries did not appear.

I'm not fit in Terminal and how to work with a command line tool, so
I'm not able to trace the error back correctly.

I created the locate data base to find the libraries and XCode has the
libraries saved in /Developer/SDKs/MacOSX10.6.sdk/usr/lib/libmpi.
0.dylib. Only god knows why it's 10.6 and not 10.7.

I tried to link to this library in the file creating the error,
namely /Users/Michael/Dev/omnetpp/omnetpp-4.1/lib/liboppsimd.dylib,
but that did not work either.

Also when I configure OmNet it shows me no Open MPI files exist:

Ah, now I see it's needed for parallel simulation. Well, I'm not sure
what to do next, I try to install Open MPI directly.

[kamuro]

Alright I got it. Go to http://www.open-mpi.org/software/ompi/v1.4/

Download openmpi-1.4.3.tar.gz

In your Terminal go to your Download folder, do
shell$ gunzip -c openmpi-1.4.3.tar.gz | tar xf -
shell$ cd openmpi-1.4.3
shell$ ./configure --prefix=/usr/local
<...lots of output...>
shell$ make all install

Go to your omnetpp-4.1 (or your version) folder
open the configure.user file

after the lines
WITH_PARSIM=yes
SHARED_LIBS=yes

add
MPI_CFLAGS=“-I /usr/local/include -L /usr/local/lib”
MPI_LIBS=“-lmpi_cxx -lmpi -lopen-rte -lopen-pal -lutil”

then
./configure

make cleanall

make dep

make

Then it works again in the Terminal, have to test the IDE though.

In case another problem appears at the end, look if you have the same
problem this guy had

So, see you soon.
