I apologize if this question is stupid. I really 
need help with linking a code with MPI library in IBM SP2 machine running AIX 
4.2.
 
The source code is compiled with egcs 1.0.2 ( which will soon 
be upgraded to 1.0.3 ). The MPI library needs to be linked dynamically at run 
time. I would like to do it with the native compiler mpCC ( xlC with proper 
parameters) :
[
 prompt> g++ -c -o mpi_mm.g++.o 
mpi_mm.cpp
 prompt> mpCC -g -o matmulC.g++ 
mpi_mm.g++.o  ld: 0711-317 ERROR: Undefined symbol: .__main  ld: 
0711-345 Use the -bloadmap or -bnoquiet option to obtain more 
information.  make: 1254-004 The error code from the last command is 
8. ]
 
Also, I read some information about collect2. 
Does this kind of combination g++ plus mpCC( xlC ) properly initialize the 
static object ?
 
Any reply is VERY appreciated. Thank you in 
advance.
 
Sincerely, Wei Ku

	Programs compiled with GCC need to be linked with GCC or you need
to manually play many additional games.  Is there a reason that you are
not using the GCC "-mpe" option to work with IBM SP2 PE/MPI?
