So the problem appears to be that the aio library is either not being
found or is not linked in properly when you attempt to build MPI
executables that use MPI-2 IO function calls, which then results in
undefined symbols.
There's two common causes for this that I can think of off the top of
my head:
1. The "mpicc" that you're using is not adding "-laio" properly. Can
you check the output of "mpicc -showme" and confirm that it's adding
"-laio"?
2. Solaris has a nasty habit of displaying misleading error messages
when you inadvertantly mix 32 and 64 bit entities when linking. For
example, if you're creating a 64 bit executable and you -lsomething,
where libsomething.a is a 32 bit library, the Solaris linker won't tell
you that you linked a 32 bit library and it ignored it -- it'll just
silently ignore libsomething.a and then complain about missing symbols.
So I'm wondering if you're seeing something like this here.
Keep in mind that you'll need two separate installations of LAM -- one
for 32 bit applications and one for 64 bit applications (and therefore
you'll have two different sets of wrapper compilers [mpicc and
friends]). So before you compile the lamtests, the easiest thing to do
is to set your $PATH to point to the LAM installation that you want
(and therefore the mpicc that you want) -- ensuring that you compile
lamtests in 32 bit mode with the 32 bit installation of LAM, and
compile lamtests in 64 bit mode with the 64 bit installation of LAM.
Can you double check that you did this properly?
