LAM/MPI 7.0b13 fails to configure and build on RS6000 AIX 4.3.3.
Thanks to Francoise Roch <Francoise.Roch_at_[hidden]>, I present
a solution for both problems.
1) The native AIX xlC compiler is not smart enough to accomodate the
configure requirements (fails on boolean stuff).
A simple fix is to install gcc/g++ version 3.2.3 (binaries available from
the IBM repository).
2) Routines ssi_rpi_sysv.c and ssi_rpi_usysv.c fail to compile because
several structures in netinet remain undefined under AIX 4.3.3.
To fix the problem, add
#include <netinet/in.h>
in lam-7.0b13/share/ssi/rpi/sysv/src/ssi_rpi_sysv.c
and lam-7.0b13/share/ssi/rpi/usysv/src/ssi_rpi_usysv.c
Then (assuming ksh syntax) a typical LAM configuration in 32-bit
addressing mode is:
export OBJECT_MODE=32
export CC=xlc_r
export FC=xlf_r
./configure --without-romio --prefix=/xxxxx/lam-7.0b13-32
The corresponding configuration in 64-bit adressing mode is:
export OBJECT_MODE=64
export CC=xlc_r
export FC=xlf_r
export CXXFLAGS='-maix64' # g++ is not aware of OBJECT_MODE setting
./configure --without-romio --prefix=/xxxxx/lam-7.0b13-64
The resulting 64-bit lam-7.0b13 libraries runs nicely on my application
and are also fully interoperable with 32-bit lam-7.0b13 tasks running
under Linux.
Enjoy.
Pierre Valiron and Francoise Roch.
