thanks
I need to compile a boot mpi program.
mpic++ -o tp2p -I/home/mypath/boost_2010_6_8/boost_1_43_0 test_p2p.cpp
But I got error:
input in flex scanner failed
It seems that mpic++ cannot accept the compiling command.
I cannot find man page or help document for mpic++.
Any help is appreciated.
thanks
