Hi,
I'm a newbie on MPI & Eclipse.
Here're my problems. First of all I installed the openmpi-1.4.1 to the default location, ( urs/local/)
then when I tried to make a test from the command line
mpicc -o testMPI testMPI.c
mpirun -np 4 testMPI
it gave errors such as
"libopen-pal.so.0: cannot open shared object file: No such file or directory"
then I uninstalled, and installed another directory:
./configure --prefix=/usr/local/openmpi-1.4.1
export PATH=/usr/local/openmpi-1.4.1/bin:/usr/local/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/openmpi-1.4.1/lib:/usr/local/lib
sudo make all install
it installed without any problem. This time I was able to make it work from the command line, the testMPI code worked well locally.
And then I made the necessary installations to Eclipse (Parallel Tools Platform, CDT, Remote something etc) by following the instructions
http://wiki.eclipse.org/PTP/release_notes/3.0
nothing to worry about. I added a resource manager on parallel runtime perspective.
it gave this error :
***************************
mpirun was unable to launch the specified application as it could not access
or execute an executable:
Executable: /home/sertan/workspace/MPI_HelloWorld/src/MPI_HelloWorld.c
Node: sertan-desktop
while attempting to start process rank 0.
***************************
Then I re-opened C++ perspective, tried to "Build". It said cannot open "/bin/sh mpicc". But it is inside the directory path I assigned. usr/local/openmpi-1.4.1/bin
Then just to give it a try, I copied mpicc to usr/local/bin
it passed that error when I tried to build from eclipse but gave another missing lib. this time.
Then I decided to install openmpi-1.4.1 on both locations. Now again it works well on command line, but not on eclipse (when I pressed build)
**** Build of configuration Debug for project MPI_HelloWorld ****
make all
Building target: MPI_HelloWorld
Invoking: GCC C Linker
mpicc -L/usr/local/openmpi-1.4.1/lib -o"MPI_HelloWorld" ./src/MPI_HelloWorld.o -lopenmpi
mpicc: error while loading shared libraries: libopen-pal.so.0: cannot open shared object file: No such file or directory
make: *** [MPI_HelloWorld] Error 127
and without build, I can't run as "Parallel Application".
I changed the library path of the project, I changed the lib path of the project, checked the builder (GCC C Compiler)
I need some help because for 2 full days I've tried to make just a simple "Hello World." and not even on cluster, on my poor local computer...
