<P>
I have uninstalled the openmpi installed through synaptic package manager on my Ubuntu desktop and installed a fresh copy of openmpi in my home directory. I have appened the PATH to /home/raashid/openmpi_install/bin and LD_LIBRARY_PATH to /home/raashid/openmpi_install/lib<BR>
<BR>
I tried to compile ParaView3 again and set the <BR>
MPI_INCLUDE_PATH:PATH=/home/raashid/openmpi_install/include<BR>
MPI_LIBRARY:FILEPATH=/home/raashid/openmpi_install/lib/libmpi.so<BR>
<BR>
I am getting a new error this time as :<BR>
