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,
