[molpro-user] Parallel 2009.1 compilation on AIX5.3

[Reuti]

Hi,

what is the preferred way to compile a parallel Molpro 2009.1 patch  
21 on an AIX5.3 operating system using xlf/xlc?

- Open MPI is currently unsupported on AIX

- Using "-mppbase /usr/lpp/ppe.poe/include" compiles up to (i.e. a  
plain MPI compilation w/o GA):

Then I tried to add -DMPIO_USES_MPI_REQUEST in CONFIG to CFLAGS and  
got some steps further - ppidd_eaf_c.c compiles fine. Now many  
symbols are missing, obviously from the MPI library as all begin  
with .MPI_... (note the dot at the beginning).

So I added to the LIBS entry in the CONFIG file ==> -L/usr/lpp/ 
ppe.poe/lib -lmpi

But it looks, like the default MPI library uses an underscore at the  
end instead of the dot at the beginning. So I added to FCFLAGS ==> - 
qextname

I removed all compiled objects, recompiled and now I'm stuck at this  
error:

Is this the correct way to do it or am I doing something terribly  
wrong? How to continue?
